Excuse me for wading into this
discussion. Especially since I have not been active for a couple years.
But I did do some operating with a THD-7A + Arrow
and with a FT-817 + Arrow and I can see no
problem with the use of a audio recorder being
used as a log (at least until one has time to

Well, I am cheering for all that endeavor for us!

LS (I bought one of the few DEMI 1268/144 Tx converters that were

To T/S the meter, swap the elevation wires with the azimuth wires and
see if the problem follows the swap. I hope you did not do what I did:
The contacts for the motor wires lay down onto the mete wires
applying 26v to the meter ckt. Taking the control unit apart doesn't
look fun.

I have been reading all the comments.
I really only QSL eme contacts. I will QSL meteor scatter once there
is some activity up here (nearest activity is 1300-miles away which
kind of tough to do. Also, I will reply to a QSL request on

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

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.
Single channel FM repeater satellites will always be s
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 that

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
