> Why not allocate digital mode above 1900 KHz?
Because 1900 and up is not available in many areas of the world.
Although I'm not happy with TJ65 at 1838 - it's far better than
the over driven SSB, ESSB and AM that was the norm between 1830
and 1850 a few years ago (and still exists in some area
Happy New Year to all
Jim, I'd love to have you as a neighbor. You know how to set up a station
for best performance. I had experience with some stations in my area that
wants to get long DX increasing power without knowing how to do it. I was
able to hear the guy on several different frequencies

If you only want to work W6 to W1, or even W6 to JA, yes. But if you

A couple of thoughts...
When transmitting, is the RCS-10 antenna switch inadvertantly changing
(switching) antennas (ports) during the transition from receive to transmit,
possibly RF getting into the switching circuit causing this ? Do you lose the
12VDC to the switch when changing from r
Ok...
I went and added 9 more radials the SWR is now at 1.2:1 after some adjusting of
the air variable
well , i decided to see how the amp (Alpha 374A) loaded into the antenna , I
keyed down with maybe 500 watts and everything went dead again in less that 1
second. So it now appears that I
Would that FCP work with my 43' vertical, three 25' top loading wires that drop
at a 45 degree angle (patterned after the NORD antenna model) and have a 160
meter loading coil that I put in series with an auto tuner at the base???
Using a less than complete counterpoise "field" - about 40 radia
well about a month ago i put up my Inv-L , it is now ~165ft , I have an air
variable in series , and 12 radials anywhere from 150-250ft long ( going out to
add more as soon as i am done typing this). my SWR wasn't too bad maybe 1.7:1
at the best. Two nights ago I added an amplifier to the mix ~7
You certainly don't need an amplifier for JT65 and most are not using
them. I worked half a dozen stations last night on 160 - mostly new
states from here in Florida - using nothing more than my 80/40 trap
inverted V and 100 Watts. Worked KH6SAT on 80 with the same antenna
and power level ... ex
I was under the impression that JT65 was a weak signal mode. 600 watts seems
a lot for that. Is that a normal power level for that? I was hoping to work
it without an amplifier.

I fired up on 1838 last night running 600W to my usual Tee vertical. In
about two hours, I worked about 15 guys in 10 states, including XE1, VT
and NC, all of
Phase noise is generated by the rig's LO and exists as a more broad band low
level signal. Issue is more significant with modern day DDS than with older
analog-type VFO sources. Guys who operate field day can relate...

Don't you mean IMD from the radio/amp driven past ALC?
