Good to know.  I need more power when 6M propagation is light, not not mention lower freqs.  Mine is on the horizon.

Have a great day,

I managed 5 FT8 contacts. The longest one was with VE2XK FN07PJ
from CM97af.

As a side note, don't worry if you don't have the right antenna.
I'm using a K3 at 100W into a 160M dipole at about 35 feet. Not
ideal, but fun.

My signal reports vary all over the place, from -24 to +06. The
+06 was from VE2XK, so go figure.

I always have a blast working DX on 6M. Maybe I should get an
antenna. :-)

To say that 6 Meters is "some what open" is massive understatement.
Indeed, it was ROARING, and has been several days a week for the last
month!  I made 66 QSOs today, 10 of them in new grids from VE9, VE3, MI,
MN, New England, XE3, and 38 JA stations. JA stations were getting
worked from as far east as Texas, EU was getting worked from the eastern
half of the country, EA8DBM and HI3T were both copied here several
times, I called but failed to work VT and RI.  Those are two of the
three stations I still need. :)  My QTH is about 70 miles S of the
Golden Gate Bridge. A few stations 100 miles or so E of me worked BD4WN.

I'm running K3/KPA500/SteppIR.

Yep. And you beat me to at least one QSO today. :)  Before I had
aluminum in the air, I worked 6M with a pair of 80/40 fan dipoles. They
were up 100 ft and fed with very good RG11. Running 100W, I managed to
make several double-hop QSOs both to the east coast and to KH6.

When I lived in Chicago, my 6M antenna was a pair of stacked horizontal
loops up about 40 ft. I remember working a guy on Long Island with his
antenna in the basement!

I always am *somewhat amused* by the "6m Open" e-mail.

My question would be how any KL7's did you work?  99% of openings do
not happen "Up here".  I'll admit not listening, kinda busy preparing
for 9,000 mile road trip.  Maybe hear us with our 80w KX3+KXPA100
(1/4 wave vertical mobile whip or Moxon when stationary).

"My question would be how any KL7's did you work? 99% of openings do not happen "Up here"."


And that is my problem! Only Alaska left to work for 6 m WAS and it seems that even in the best openings there are very few Alaska stations even listening. Yesterday I did see that KL7KY and KL7HBK were shown as FT8 listeners by PSKReporter but I couldn't raise either. That was on a day that I worked Canary Islands in the afternoon and Japan in the evening.


So what is the the magic set of circumstances that opens a 6 m path between AK and AZ?

It's important to understand how E-skip works. It's called "sporadic E"
because it depends on sporadic activation of the layer for reasons that
are not understood by me. Propagation from E-skip is often "spotlight"
in nature, especially when more than one hop is involved. We can work
"single hop" when the ionized cloud is roughly midway between us and the
other station; for two or more hops, at least two ionized clouds must
line up -- that is, ground to cloud one to ground to cloud two to
ground. With double-hop Es, it's common to be able to work stations
within a radius as small as 50 miles. And then one or both of clouds
moves and a different radius is illuminated.

Yesterday, for example, from here near San Francisco, stations 50-100
miles E of me were working China, and stations in TX and OK were working
JA. I heard none of it. But at various times, a single skip cloud
provided a path down to San Diego and into XE, another into AZ, S NM,
and S TX. That was all before noon. Eventually I started seeing the SE
US -- AL, FL, SC, GA, NC. Toward evening, we started seeing (and working
New England and the upper Midwest (8-land). And so on. VT was there for
perhaps an hour, then gone. Same for RI. VE3 was there for about an hour.

After dinner, I returned to the shack to see a screen full of JA. It was
roaring for at least an hour -- but around 10:20 PM local, it quickly
faded.

A great place to see (and study) this is this map. It stays in my
browser during Es season (roughly May to July in NA). Once in a while,
click on the <MUF ES> all the way to the right above the map.

Hi Gregg,

 From where I sit, the advantage is that FT8 allows operators who don't
know CW to "light up" a grid with modest stations and make QSOs under
conditions that simply don't support a SSB QSO. Yes, CW is MUCH faster
-- IF there are good ops on both ends. But FT8 also goes at least 6 dB
deeper into the noise than CW, and CW is at least 10 dB better than SSB.

I worked 40 new grids last season, and 40 new ones this season. Last
season, all but three were worked with WSJT-X.  Eight were MSK144 to two
hams doing grid trips. The rest were evenly split between JT65 and FT8.
This year I've ONLY worked FT8. I estimate that at least half of those
80 grids have no hams who work CW and are active on 6M.

I built a K3S a few months ago and I've installed the K144XV 2 metre
transverter into it, along with the K144XV Ref lock option.

Although all of the main K3S calibration is OK, I find that the K144XV is
about 200Hz off nominal frequency, certainly in the 144-146 MHz segment.

The manuals mention calibration being automatic, so I can't find any
reference to adjustment where the frequency is incorrect.

Anyone any ideas how I can get the transverter on frequency across the band?

Answer:  Sunspots........

I have worked many Alaskan station when the sunspots accommodate,  from here
in Virginia.
We're talking F-2 NOT E layer.

One of my first was with a guy running ten watts to a Halo on his 2nd story
garden apartment.

It seems as the MUF goes higher, it takes less & less power to make the
contact.

73, Charlie k3ICH


WAC, DXCC @ 156 countries, and 1st Virginia to make WAS on 50 MHz However, I
do NOT chase grid squares.

Andy,

The problem is there are few stations in Alaska, whether they work 6m
or any other band.  About 2002 it was stated there were 3802 licenced
hams residing in AK.  Now you know half of them never get on at
all.  Out of the other half 50% do only HF: the other 49% do only
VHF-FM.  That leaves 1% maybe 38 hams spread over an area 2-1/2 times
the size of Texas.  In fact there are spread.  50% of the state's
population lives within 100-miles of Anchorage (pop 370K), then
Fairbanks (about 80K).  6m Es work into the Fairbanks area more often
than south of there.  KL7NO is well known 6m op up there.

I live 65-miles south of Anchorage (KL7KY and KL7HBK who are devout
sixers) often have Es and I don't or vice versa.

Then there are hundreds of square miles without anyone (let alone a
ham).  Who you gonna work out there on the Tundra?  A Cariboo or
Bear?  Es do no good it not landing in the very limited populated
locations.  Then Es are (evidentally) more common in lower latitudes.

The *real* answer is EME.  Prop is open for eme when the moon is up;
happens every day.  Yes, there are parameters that make eme better or
worse so maybe say is available half a month, every month.

And that is why I am building a two-antenna 6m eme array.  So all you
down there can achieve WAS.

I will not be QRV until September with new array.

We only have to wait maybe, 5 or 6 years.
I think we're at, or near,  the 11 year cycle minimum.

If you think E openings are great, as the old saying goes, "You ain't seen
nuthin' yet" when the F-2 thickens up.
 Unless the next peak is a wash-out for six meters, there'll be times when
you'll think your band scope is stuck on 20M.

JA stations so thick, they'll spread out as high as 51 MHZ and I mean from
the east coast !

Alan,

Did you check the Frequency Calibration section of the K144XV option manual?
Look on page 19.
You can adjust the offset with the K3 menu XV1 OFS.  The offsets for
each band segment should be indicated on the XV144 top cover.  If you
have accurate frequency beacons available, you can refine those offsets
as needed.

Hi Don.

I am aware of the manual method of configuring the offsets and I originally
used that before I installed the K144XV Ref lock option. The Ref lock option
manual infers that all offset calculation is automatic when the menu is set
to REFLOCK and user calibration can't be undertaken. Is this not the case?

I have not worked with the REFLOCK, but I believe the XV1 OFS parameter
must still be set in the menu.  The REFLOCK cannot read the labels on
the top of the K144XV.

 From the K144XV Reference Oscillator Phase Lock Option Installation Manual:

Recalibrating the K144XV

With the K144 XV Reference Oscillator Phase Lock option installed, you
no longer need to calibrate the two crystal local oscillators as
described under Frequency Calibration in the K144 XV Installation and
Operation manual. Once the proper settings are made in the CONFIG menu,
the calibration occurs automatically as both oscillators are phase
locked to the master K3REF oscillator in the K3.

Enable the calibration as follows:

Be sure you have K3 Firmware ver. 4.42 or later installed.

Tune the K3 to any frequency in the 2-meter band.
Hold CONFIG to access the CONFIG menu and select XVn OFS, where n is the
transverter number you assigned to the K144XV (see Enabling the K144XV
Module in the K144XV Installation and Operation manual).

Tap the 0 switch until you see REFLOCK on the K3’s LCD. The
automatically calculated offset will appear in upper half of the K3’s
LCD. This enables reflock for both the 144 and 146 MHz band segments.

You don’t have to repeat the procedure for each segment.

If the K3 EXREF option is also installed, the K3’s reference oscillator
itself will be automatically calibrated by the external 10 MHz
reference. In this case, enabling REFLOCK for the K144XV module will
allow the K144XV frequency to track the external reference. The accuracy
of the 2-meter frequency will be less than that on HF by a factor of
about two, due to the higher frequency of the K144XV local oscillators.

I have that installed in my K3 along with the EXTREF module driven by a
10MHz GPSDO. From a cold start the automatically calculated offset can
be seen to change +100Hz as the TCXO drifts with warm up.

Belief and reality ain't necessarily the same thing.

Regards,

Mike VP8NO

Hi Don.

I just got back from 'experimenting'!

I turned the Reflock off and manually set the offsets according to the
figures on the Xverter top.

With the Reflock still turned off, the discrepancy is several KHz (I did not
note the exact figures).

With the Reflock turned back on, the discrepancy is back to around 200 Hz
and there's no way to manually adjust that in software.

I wonder if the K144XV itself is a tad off? I bought it from another amateur
so I don't know its 'tweak' history, other than I have never adjusted any of
it internally.

Alan,

I have not worked with the REFLOCK, but I believe the XV1 OFS parameter
must still be set in the menu.  The REFLOCK cannot read the labels on
the top of the K144XV.

Hi Alan,

that's true. What I did (was off a few hundred Hertz, too) was to
calibrate the main reference oscillator with REFLOCK enabled from a
stable 2 m source. Worked well.
