K3 with the w2ihy audio gear

[Arthur Nienhouse]

Scott
I have been using Julius 8 band box since he first came out with it and
still have it driving K3.
The main reason is the noise gate is better than the gate in the K3, the
gate in the K3 needs to have more
canceling on the back ground noise I can literally watch tv with the
volume low four foot from the mic and talk on the radio with out the tv
audio coming in over my voice, and its easier / faster to turn off the
audio effects or change the gate as well.
It will surly killed the amplifier fan noise as well used to chase grids
on 144 mHz the Command II fan was very noisy
the Julius box gate fixed that problem.

I use the ATR 30 which I bought for $22  a few years ago and it came
with a 16 ft cable XLR to 1/4 in plug , I have a GOLDLINE PRO as well
the only difference is the PRICE.

What is the recommended solution to the requirement of a 5w dummy load
during assembly of the K3?

Any 50-ohm non-inductive load will do, as long as it will handle the
power.  You can use any one of a number of commercial products, or
Elecraft has the DL-1 kit that will do.  Just make sure the load is of
good quality.  A light bulb does not meet this requirement.  It is very
possible to make a suitable load using one of the Caddock 50-watt 50-ohm
"chip" resistors and a heat-sink.

Hi James,

                 Very good quality used ones, and pretty cheap too, here:

https://www.ridgeequipment.com/store/dummyloads.html

Nice additions to the tool box for the future for $12 (75W)  or $7.5 (15w).  
Pick up any adapters you may need too.

NFI but a satisfied customer.

73,
Bob

Good afternoon James,

You are not restricted to a 5w dummy load, you can use any dummy load of 5w or
greater.

If you don't have a dummy load, Elecraft has a 20w dummy load kit:
DL1 Wideband 20W Dummy Load

You can find it at: http://www.elecraft.com/mini_module_kits/mini_modules.htm

Enjoy your K3!

James, there are many possibilities, but if you want a quality dummy
load at a reasonable price that is also flat (is a constant 50 ohms
non-reactive) to above 500 MHz, take a look at the 75 watt dummy load
offered by Ridge Equipment
https://www.ridgeequipment.com/store/index.html.  It is $12, but you
will likely want to buy an adapter to the N connector if you don't have
one already.

Caution, this dummy load is rated at 75 watts, but I would not try to
push it to 100, even for a short time - those elements are "touchy".

Hi,

I highly recommend this dummy load. I have 3 of them and I routinely expose them to 100+ watts for short periods. My IC-7200 typically puts out 120W on a 14V supply. I do not think these dummy loads are "touchy" at all. They are probably mostly thermally limited although it's likely that something will fuse if really high power is applied. 100+ watts, no problem IMHO.

PS: NFI here, too, but a very satisfied customer.

I built my own using 3 150 ohm 2 watt resistors from Fry's
Electronics. I put them in parallel with the wires on one side
soldered to the center connector of a coax connector. I bent the
other wires back over the resistors and soldered them, along
with some coax braid to the connector shell. Testing the result
with a MFJ antenna analyzer showed 1.0:1 through the HF bands
and about 1.3:1 on 2 meters. Result: a 6 watt dummy load.

For more power, I probably would by a commercial dummy load, but
this solution involved the least travel and elapsed time.

Regarding the Gate on K3... This is no longer the case.  And
the issue that KA9ZAP describes is a mic pattern issue, not
a gate issue.  

The gate now has great hysterisis on release and is
extremely smooth ramping the audio.  It has none of the
nervous hunting it used to have. And the issues with
autonotch and distortion have been fixed, as far as I know.
I have a very noisy shack, with hard reflecting walls (Im in
the garage) and using TXGATE with my amp on, at 18, it is as
good as any RDL, Aphex or dBX professional audio gating
product I have ever used.

As far as the Equalizer, I like Julius' products, they work
well for the average ham.  But this rig doesnt need the
help. I tweak the W2IHY gear at NQ4I for phone contests
(Rick's 20, 40 and 10m run stations using Orions are all
W2IHY processed).  At home, I previously had a rack full of
Behringer and dBX gear.  It now sits idle. I dont need it
anymore.

With the Yamaha CM500 boomset, gate, "CMP" and EQ in the
rig, I find that K3 audio is 99.5% perfect for my needs. Be
advised that mic placement and mic technique goes a long way
to maximizing the audio within this rig. It likes consistent
input levels for good modulation depth.  Dont be afraid to
light up all the lights on the CMP meter so that the last
one only flickers.  I keep CMP below 25 and with my CM500
and voice, Mic Gain at no more than 30...YMMV.

The rig can make most any mic and voice sound great all by
itself.

And Im rather picky...
