1. I had fun.
2. I read the Guide before, during, and after the test.
3. I started to 20m and was confused. Partly because I was not
hearing the FOX and was seeing stations below 1K with "R-12" reports.
4. On 20m, it did not help that XE1GK was calling CQ on top of W1/KH7Z
+/- 1HZ (I did see KH7Z a few times with reports). Being in W3 I
would not "expect" to hear a W1, but the XE1 was -1 to -15 didn't help.
5. I saw CQ on 30m. Since I could see both sides of the QSO, I was
"starting" to figure out the change in freq to below 1K.
6. On 30m, now that I was calling, I figured out the Split Operation
Rig/Fake It set-up. I changed to "Rig".
7. On 30m, I realized, now that I could "see" the FOX that my RX
bandpass did not cover 300Hz.
8. My KX3 with "Data A" has a wide bandpass of 400Hz to 3500Hz and
shifting the RX down was not going to work with the software shift
for the report, I "guess"...
9. I changed my KX3 to USB, removed CMP and RX/TX audio EQ. The
lower RX cut-off would receive the FOX on the assigned freq.
10. I looked at the KX3 manual C5 for a way to set the passband low
end cutoff while in Data A mode. Nothing found. Does the K3s have
the same problem?
11. On 40m, I now knew what was going on... I heard the CQ, The FOX
answered my GRID and the software moved me between 300Hz and 900HZ
(the manual does say that) but until it happens, I was not sure what
it meant. The FOX never "RR73" 'd me. I was running 10 watts.
12. On 80m it was the same as 40m. I was running 15w (with a fan
blowing on the heatsink). I never finished a QSO.
13. I had fun and thank you for the DXpedition effort.
14. I need to see what Elecraft has to say about the "Data A" low freq
cut-off setting...
