Hi Bob,
Whatever the satellite, if you're trying to stretch the footprint, your sked
is always going to be at the peak of elevation, for that fleeting moment when
the satellite is a few degrees above the horizon. That means that you're
always going to be at zero doppler

I'm looking for a winter project can any one point me in the direction of a 2
meter tube amp nothing crazy about 25-50 out, 1-10 in. I have never used or
played with a tube circuit so i thougt winter why not. Thanks 73

Hope everyone had a great holiday season and found some new radio gear
under the Christmas tree. It is time again for our net tonight at 8PM on
Echolink N2EYH-L or on the Mt Beacon repeater at 146.970 pl 100 on your dial.
We
hope to have one or two Amsat area coordinators joining the net to
Mineo, is there any update on the status of FO-29?
I think there was an expectation that FO-29 would emerge from eclipse
induced coma sometime this month. Is there still reason to be hopeful?

For the tube, I would recommend a QQV06-40 if you can find one.
Was used extensively in the VHF mobile radio market (both for mobiles in the
1960s and base stations)
Will need a 600V anode supply, 250V screen grid supply and 6.3 or 12.6V heaters.
Can't find a specific design, I would just put
I would try to locate old QSTs or Amateur Radio Handbooks that contained
such circuits. Tubes such as 6146, 829, etc. were good candidates. Also
the 4x/4CX150 would give up to 100+ out with just a few watts in. Newer
handbooks or magazines still provide you with he necessary theory to
build
Agree, and even old tubes like the 2E26, 832, etc are good tubes for this power
requirement, but the problem is that tubes from that vintage are usually sour
by now, if you can even find one. I'd suggest looking for an 'Oldtimer' whom
never threw anything away, like my dad (SK) and you might
Try to find an old 1950's ARRL Handbook, I am sure there are some projects like
that in there.

Things like 6146 struggle on 10M.
You're expecting a lot getting it to go on 145MHz.
QQV06-40 or 2C39 are better bets for VHF.

Not a problem when running them reduced power. 6146Bs worked well up to
50mhz and at half power ran them up to 2 meters. 2C39 will easily work
on 2 since I have used them to 1.2 and 2.3 ghz. However, they are harder
to socket them. All of the tubes mentioned (and others) are available as
I also uploaded a file with WiSP. Hope you can download it OK.
It would be nice if other voice users did not transmit until the
packet transmission has stopped though.

You didn't say what band or what mode but you could us a couple of FM Prog
Line dual 6146 strips to remove the few parts and have a tube that you can
beat on and still replace with inexpensive new tubes or NOS.
If you were just running FM, you could just whip up an input circuit and use
the strip
Ah...I now see that you wanted the amp for 2 meters...eyes are getting old
or I have been staring at RF tuning adjustments too long...
A GE Prog Line will drop right down for you.

Hi Drew,
SatPC32 is probably an excellent program (I'm on Linux here, so can't use it),
and if you've got the automation available, that's certainly the best way to
go. And, by definition, the lower the elevation, the farther away the
satellite is, so your DX contacts are going to be at the

I disagree that Doppler shift will be zero when your window to work
