Shortly Elecraft will be offering a 2m module for its popular new SDR

bottom of the page the direct signal was 60-dB S+N/N and Moon echo
was 20-dB S+N/N. Received on a 40m inverted-V with a FT-847 2.2 KHz
bw in USB. Absolute signal level was affected by AGC.

Hi Zack!
I don't mean to be the odd guy on the block, but I do not like the 8800 for
satellite work. I enjoy the full duplex function, and it is very easy to
maneuver through the frequencies/bands using the mic, but I do not
Zack,
Do you have any way to measure RF output power from the radio? A
power meter (or SWR meter) that indicates forward power. If you do,
measure power with Arrow connected to output of the meter. Measure
reflected power (or SWR). If you have a dummy load connect it to the
meter and test
In the process of re-building my wind-damaged satellite antenna array
and got thinking about the mode-S sats.
I will be installing a 8dBic (RHCP) patch antenna (bought from L-Com)
and have two different Drake downconverters to chose from depending
on what the uplink band is. I am guessing
A satellite with 25 channels would probably help. LOL This is why
a lot of the old guard satellite ops wish for the translator days
with 100-KHz of bandwidth and CW/SSB. But I do NOT want to start up
a RANT on this -everyone knows this.

Pretty good guess, David. These days newer HT come with
Nickel-Metal-Hydride which do not need the kind of maintenance that
NiCD do. Typically they hold charge much longer and do not develop a
memory condition.
At my former employment (now retired) we maintained over 200 HT

Timely info, as I am going to rebuild my directional satellite array
this week using:
144: M2 2M7 12.4-dBi (vert-pol)
432: M2 436CP24 14-dBic (est.) RHCP (rear half of 436CP42)
2401: L-com Patch 8-dBic RHCP
No L-band

I may add pol switch to the 432 x-yagi later
Nothing heard during the 0145z pass (#65.199). Did it not switch?

I was scanning the DEMI catalog when I noticed that DEMI is offering
a xtal for their 1296 transverter which put it on 1268-MHz.
The transverter is offered in 25w or 50w:
25w: assembled $590
50w: assembled-only $800
1.5w: kit for $395 (might be adequate for satellite if mounted right

Few more comments:
Running 50w into the Lindy works the middle of the pass, OK on
