Re: KX3 Amp

Yes, but.....

The original poster is going to be 200 miles from town. He may or may
not be in VHF range of something when he needs help. I'm pretty sure
he's out of range or he'd just get a couple of handhelds and call it done.

The Personal Locator Beacon frequency is monitored by two sets of
satellites -- a constellation of low-earth-orbit satellites that can
determine location, and a few geostationary satellites that see a wide
area of the planet, looking straight down at the surface of the earth.
The latter can read the GPS on the PLB.

The signal goes straight to search and rescue folks, and the beacons are
registered so they know exactly who they're going to be looking for.

Which would you prefer: push a button and it's done, or calling on
several bands and hoping one is open?

Again, I love amateur radio, and I would consider it part of my
emergency toolkit, but I'd trigger my PLB first in a real emergency.

Well, in that framework - I would have to agree that the PLB is better .....
How do I get one .... :-)

Re: KX3 Amp

I like Walter's paper and risk management approach and also with the philosophy of needing 2 way communication to manage logistics. Personally, IMHO, the Satelite phone rental is probably the most effective way. I personally don't travel more than 10 miles from the trail head so I have gotten by with HT/GPS/APRS and a small HF rig. I also carry a standalone GPS for trail maneuvering. A coiled up twin lead J-pole is quite effective and can be configured for 2m or 11 meters. When I was on Pisgah Mt in NC, I had no problem hitting the repeater on Caesars Head in SC, which gave me an effective range of 100 mile radius with that J pole strung up on a tree and the TX on the HT at 5w. Preparation and redundancy is key - even backups for backups. "He who does not have a backup plan better be really lucky". Waiting patiently for the Elecraft 2m module.....

Re: KX3 Amp

In reply to this post by ny4g

PLBs actually aren't legal for sinking ships (or crashing airplanes),
there is a different category of device for that.

Personal Locator Beacons are meant to do one simple task: summon help in
an emergency.

Calling someone to tell them you're at a different trailhead is not an
emergency.

If I'm off in the backcountry, I'd suggest that a medical emergency and
risk of being overrun by a wildfire aren't that different.

If you want to report a wildfire that isn't threatening you, that isn't
an emergency, and if it takes you a bit to get an antenna up, and find
someone to relay a message, then by all means pull out your KX3 and a
random bit of wire and tell someone.

A satphone (according to your post) is about $120 for a given outing. A
PLB is about $250 for five to seven years.

It's good to have more than one tool in your toolbox.

Re: KX3 Amp

In reply to this post by Lynn W. Taylor, WB6UUT

I read the blog post. That's where I found (your) satphone pricing, and
your comment about calling to be picked up at a different trailhead.

Your blog post does not address the original post -- he wants a 100 watt
amp for reliable emergency communications from his home located 200
miles from "civilization."

Different requirements, different answers. Often, more than one correct
answer.

RE: Re: KX3 Amp

I have a Delorme GPS and SPOT PLB but....limited to text messaging IF it can connect. I'd rather avoid emergencies too and good comm's are a huge help, "..cross river here not there" , "..unfriendles spotted near x" , " Erdu at point Y" ,"meet Joe at point x..." , then able to talk with Joe as we approach , etc.. Nothing lke real time phone to keep a trip safe and productive. 2M would be nice but we have seceral small HT's for that.

So , rather than discuss why I could use anything else..does anyone know of a good portable amp for the KX3 ?

Amplifier advice greatly appreciated.

Thanks

Bill

RE: Re: KX3 Amp

In reply to this post by ny4g

While all these posts have good advice for a bc trip , I really just want the KX3 amplifier. I have the other items already ( Delorme GPS plus SPOT with rescue insurance paid up, sat. phone rented , several 2M HT's ( APRS godd idea , I'll add that ) and the usual flares , panels , noisemakers and things that go bang ) .

But...I need an amplifier and the right antennas to add to this.

We will be doing the check in via SPOT , sat. AND am. band.

SPOT loses lock in jungle and mountain ,vso do sat. phones and GPS.

Certain unfriendlies like to jam their freq's as well.

In addition to that any or all that gear can be broken , lost or confiscated by certain sticky fingered locals ( it.s happened ).

Hard to jam 6M-160M all the time though.

I am not "shouting in the dark" for rescue. We have several pre-planned operators standing by with preplanned times and frequencies and backup frequencies.

But, they are also mobile or may have interference so I want the best chance at a clear signal both ways.

There are no repeaters out there.

This is in Africa.

Please , any KX3 amplifier advice ?

Ten-Tec , Hardrock , etc. , which specific models with setup/operating tips ?

Greatly appreciated !

Bill

RE: Re: KX3 Amp

In reply to this post by Jim Brown-10

I appreciate the low power is better for longer advice but..this is for that crucial 5 min. of comm. when low power just doesn't work.

We have several 13500 MaH/5A power packs that combine for 20 plus amps and weigh about 1lb. each. We also have the vehicle batteries , aircraft batteries and 2 field solar 1KW ( I think, not mine ) chargers with built in Li,ion batteries.

I hope it's just 5 min. at 5W 3 times a day for 4 weeks but...JIC , the 10db could be a real life saver.

So , I have the PLB , the sat. phone and the GPS.

Does anyone have KX3 amp. advice m

Greatly appreciated.

Hands down the KXPA100. It isn't out yet - shipping in August but offers the greatest flexibility with a tuner and portability. The Hardrock is ~$260. It is only available to members of the Yahoo group right now. It is 160-6m and generates a solid 50w from 160-10, less on 6m. I own a Hardrock and it was a difficult build but Jim Veatch helped me out a lot - WA2EUJ. No tuner though so you will have to invest in a ZL100 or equivalent. The Elecraft tuner is faster and tunes a wider range. Size wise is only slightly smaller than the Elecraft 4 1/8 wide and tall by 7 deep. The TenTec is a larger amp - $800 plus a 100w tuner. The THP HL45B is a solid performer at about $450 from HRO. Again you need an outboard tuner. You have to manually switch bands. If you don't it will go on standby - a self protective feature. I played with a THP for a while and it works well. You can get one used - not easy - for about $250-$300. There are the RM Italy variants - beware do no
t overdrive - IMD artifacts - HL300B is the model - only drive to 100W - I have no experience with this amp. These are not certified by the FCC. Some people have had great luck with the Juma 100w amp and some on the reflector may have owned one or built one. The Jumas can be programmed to band switch with the rig. Again - it needs an external 100w tuner.

So here are your choices:

Juma 100w - no tuner - band switches with rig automatic - FCC certified
Hardrock 50w - no tuner - manual switching - not FCC certified
TenTec - 100w - no tuner - band switching with rig automatic
HFPacker - 50w - manual swiching
KXPA100 - 100w - tuner - automatic band switching - FCC certified
THP HL45B - 45w - no tuner - manual switching (except for FT817) - FCC certified
THP HL100B - 10w - no tuner - manual switching - not FCC certified
RM Italy HL150 - 150w - no tuner - manual switching? not FCC certified
RM Italy HL300B = 300w - no tuner - manual switching? not FCC cerified

Antennas
Too many to list
Personal favorites - G0GSF- multiband dipole - 4 bands are OK w/o a tuner, EFHW - cut to 45 ft with EARCI matchbox KX3 tuner will match 80-10m

Re: KX3 Amp

One other choice and this is probably not widely known but the THP HL450B will put out about 200W driven at 12W from the KX3. I ran one with my KX3 before I sold the KX3. It is a pricey amp. I think someone quoted it as the highest $ per watt but it does work real nicely. Needs large 13.8 VDC source rated at 60 amps at full 400W output.

Good luck!

Re: KX3 Amp

In reply to this post by Giff Hammar

Hmm, reading all this and wondering (wanting) more clarification of
what is meant by "We are going out over 200 mi. from
the nearest real town...".

That would describe 75% or maybe 90% of Alaska. If this is a
short-term camping trip or vacation it will be a bit different from
living full-time (Off the grid). I know a little bit about both
situations (serious backpacker in the Sierras in the 1970's; lived
totally off the grid for ten years in "near" bush Alaska. I did have
a dirt road but no electricity, phone, running water, etc. Three
years of that I lived in a 8x10 foot wall tent. But I had a 1700w
gas generator, 100AH marine battery, HF and 2m radios, battery TV and
car stereo. I was 25 air miles (and 90 road miles) from a large city.

I used my 2m radio to access a repeater with a phone patch or walked
to a neighbor that had telephone. Nearest ambulance service was 50
two-lane mountain road miles away (took 1-hour response time after
contact). Fire dept was also that far away. GPS had not been
invented, yet. Marine rescue was via VHF channel-21. Loran-C was
the standard navigation tool.

Today, I would probably consider having both ham radio and an
alternative (just in case). What I got would depend if this is a
short trip or living full-time. People in bush AK often have
satellite internet and TV, and/or sat-phone. The "old days" in AK HF
ham radio was a major communication link (for everything).

When living out in the bush one develops good neighbors and a lot of
self-sufficiency (and being very careful). I lived alone so no one
would likely come looking for a couple weeks or more. This is more
so if a backcountry traveler.

Re: KX3 Amp

In reply to this post by ny4g

One correction. The HF Packer is not a 50w amp. It's about 45w at 160m,
and then steadily less as you go up in frequency (40w for 80m, 35w for
40-20m, 30w for 17/15m, 25w for 12m and about 20w for 10m). It doesn't
support 6m. These numbers come directly from a graph in the HF Packer
manual.

I played with a THP for a while and it works well. You can get one used - not easy - for about $250-$300. There are the RM Italy variants - beware do
no

> t overdrive - IMD artifacts - HL300B is the model - only drive to 100W - I have no experience with this amp. These are not certified by the FCC. Some people have had great luck with the Juma 100w amp and some on the reflector may have owned one or built one. The Jumas can be programmed to band switch with the rig. Again - it needs an external 100w tuner.

Re: KX3 Amp

In reply to this post by Giff Hammar

With all the banter about KX3's and amp's, on batteries for "Emergency"
use.

Please remember, that battery makers specify the AH figure, for a typical
C/20 rate, (1/20th the nominal AH current value.) Some may quote it at
C/10, check the data sheets for the battery of interest, they will often
have example of typical discharge voltage curves, for various discharge
rates too. That can be *Very* enlightening!

Without going into specifics, 20A from a 7AH battery may on the face of
it give you some 20 minutes operating (7 / 20 * 60) but in practice you'd
be lucky to get even near half that of actual "Practical Use" of your
amp'. Probably no more than 5 mins TX time at most before it all starts
to collapse.

The charge/discharge efficiency of SLA (and most other batteries) falls
like a stone with high discharge currents, also, also the voltage is
lower at high currents as the battery nears "empty", but many high
current loads (Amp's etc) don't work well (if at all) at those lower
voltages, so in practice you get even less usable run time..

Try your intended battery with something else that is a similar load,
while monitoring the voltage...

For Lithium family cell's, they (should) have a monitor circuit that will
simply cut off the load to prevent over discharge (and resulting thermal
"instability") leaving you totally dead in the water as it were.

As others have said, if you don't already have the needed techniques, opt
for some narrow band mode (the built in PSK31 if your CW is not good
enough?) to get a message out if needed via as resonant as you can get it
antenna.. Even 3W of that can be reliably decoded many 100's of miles
away, on the right frequencies. Don't forget the counterpoise if using
a wire. However, farmers fences can make good grounds, also antennas at
times! :) (Avoid "Electric" fences of course!!!)

A repeated short distress message (SOS or PanPan Medico?) including an
international grid reference, sent on one of the QRP frequencies, I
suspect would possibly result in some action, but I wouldnt garrantee it
on HAM bands sadly..

Remember too, what is said somewhere in all mobile phone handbooks that I
have ever seen (that no one ever reads) "this device uses radio signals,
that are by their nature unreliable, you should therefore not rely on
this or other radio service for emergency call's." But what do most
people cite for their ownership of a mobile 'phone? "Use in an
emergency"!

If you **NEED** such comm's, perhaps a satellite 'phone is more
appropriate, and even they are not without issues. Or carry an EPIRB
with you if you're hiking well away from anywhere. Activate one of
them, even on land, and all heck will come your way in very short order!.
Even a sat'phone and EPIRB are lighter and smaller to carry than a KX3,
amp and battery...

But best of all, tell people you trust more or less where you are going,
and your planned route + intended return date/time, and whatever late
tollerance figure you think, just in case of delays. Then, if you don't
appear, or contact them from elsewhere by any means, they can call the
cavelry out. Of course, if your plans change "on the fly" get a message
back to them, to that effect...

Enjoy the outdoors, but stay safe. If you have known medical issues
(type one Diabeties for example) talk to your doctor before planning any
extended trip out "into the sticks", just in case.

Given the choice, I'd prefer to ensure I can cary/find enough water &
food, also perhaps a simple bivoac shelter kit for any significant hike
out, also any needed indiginous venom antidotes etc, than carrying any
Ham Radio gear I think.

Regards.

Dave G0WBX.

Another correction. HLA 300 (and probably 150) have RF sensing PTT and
automatic band switching. They also have decent IMD is not driven to full
output power. HLA 300 is about 25-30 db IMD when driven to 150-200 watts
(5-7watt input) and cost under 500 USD. No antenna tuner though.

I get 44-45 watts out of mine (v3) on all bands with 5 watts input. I've seen 50 if I push it with 6+ watts input when I was testing it out, but that's in excess of recommended input limts and given the slim dB gain, not worth it.

RE: KX3 Amp

In reply to this post by Mel

Much appreciated.

This is what I found on these amps –

Yes, I bought the dang Italian Amp because that is the ONLY one I could actually get BUT if anyone has the TEnTec (418 I think, 100 amp, DC powered , portable , new model )and wants to sell it (working as new, no glitches , decent price ).. let me know.

TX - Tokyo HiPower HL45B – anything over 5 amps can blow the caps in this unit so some have put attenuators between the KX3 and amp

HFPacker – won’t be available in time

Hardrock50 – also not available immediately so I can test

Ten- Tec – found new 100W model, looks perfect – once again – VAPORWARE – just like the KPA100 – much hype, much talk about availability , much “we’re just trying to get it perfect” – Nothing available and no real idea when it will be

KPA100 – I think I’ve seen a unicorn but I’ve never seen a KPA100 that I can buy. Last December it was “ just a few more tweaks, parts in house, ready soon, blah, blah , blah “. OK, I want it perfect too but nobody can vouch for it , try it or buy it based on a promise. This is exactly what I want – in theory.

In “theory” by the time I get back from my trip I’ll have bagged a lion , a zebra , several large plains game species , a huge WoBo and a gorgeous , young South African gold mining heiress who wants me to handle all the profits from her multi-billion buck empire. But – should I start ordering the new trophy room yet and send out the wedding invitations (wife may object, should I ask her ? )? Maybe not.

This works very well for the week end warriors etc. Add a solar panel and the duration goes way up. Add a resonant antenna not needing a ground and you gain again. Add a small amp and suitable battery with upgraded solar panel and you go up again. Add an RV with internal batteries, and the night goes on. Anyone keeping score??

Pick you battle and you will always be ahead. If you try to win the war with entry level, you lose. I personally pick my battles carefully and watch my allotted budget, I win.

Jim is right in one sense that the 100w amp will consume battery life quickly. However, if what you want is the ability to get a signal out at marginal propagation conditions, then a 50 watt amp if used frugally can get a stronger signal out. Several amps fall into this category with about a 9 dB gain in signal strength from 5 watts - and pulling about 7-10 amps of drain on the battery on TX - Tokyo HiPower HL45B, HFPacker, and Hardrock50. The latter 2 you have to build yourself. The Hardrock is only available used if someone is willing to part with theirs. Only about 100 of the Hardrocks have been built. Sales are on hold pending FCC certification. The Elecraft amp can also be tuned down for less power out and can be tuned to 100w if needed. You do have to carry enough battery to sustain the anticipated TX time. You will be surprised at how effective 5 or 10 watts can be and effort is probably better directed at effective antenna
systems. 100w into a dummy load th
at radiates (my way of describing a poor antenna) is a poor substitute for 10 watts into a resonant wire. Up high and in the clear is always better. I have always had better luck with wire in the clear than verticals on a picnic table in terms of reach.

RE: KX3 Amp

In reply to this post by Igor Sokolov-2

Thanks.

Just to try it I bought an HLA on Amazon, with fans.

I have the built in optional Elecraft tuner, some other 100W autotuners and a few antennas that just might be resonant at the right freq:, 10M during the day, 40 and 80 later on. Hopefully we just chat on the 2M until over 20-30 miles out and base has a big antenna (beam they tell me) to pick us up when farther out (we hope).

I’ll add a fan switch and a temp. sensor from a PC unit I have.

Fans burn juice so I will keep them off unless needed.

I really want the Elecraft KPA100 but I also want a guaranteed trophy without doing a canned hunt…

Which is more likely to happen by end of July I wonder?

Bill

RE: KX3 Amp

In reply to this post by Igor Sokolov-2

Just FYI, I got the Elecraft 100W amp in two or three weeks ago. At over $ 1100 it better beat these other amps. It has a tuner but I also have the ATU in the KX3 and two more discrete ATU’s for higher power, balanced (PAL) , etc.

Have you tried the Elecraft amp yet ?
