[amsat-bb] Recap on my radio tests with AO-85...

[Patrick STODDARD (WD9EWK/VA7EWK)]

Hi!

Since AO-85 was launched in October, I have been testing different HTs to
see which ones can work this satellite full-duplex and writing about those
tests here on the AMSAT-BB list. Other than the ISS U/V cross-band
repeater, it has been a long time since we have had a U/V FM satellite
(going back to SO-35 in 1999-2001). To make it easier to reference my
posts, I'm listing the links to them in the AMSAT-BB archive here...

For the Wouxun KG-UV9D, I posted my first comments about using that on
AO-85 early on the Saturday (10 October) following the launch:

After additional testing, I wrote more about this radio last week (Monday,
23 November):

I first wrote about the Wouxun KG-UV8D with AO-85 on the Sunday (11
October) following the launch:

and after additional tests, a post late last Saturday (28 November)
evening:

I briefly wrote about the AnyTone TERMN-8R just before the AMSAT
Symposium, on 12 October:

and wrote more about it after testing it last Thursday (26 November)
evening:

I tried a Puxing PX-UV973 last Friday (27 November), and wrote a report
about it that morning:

http://amsat.org/pipermail/amsat-bb/2015-November/056238.html

Not that it really needed to be tested against AO-85, I tried my Kenwood
TH-D72A HT the same Friday I had tried the PX-UV973. I posted a report
about it late that evening:

http://amsat.org/pipermail/amsat-bb/2015-November/056245.html

None of these reports include the occasions I varied the transmit power
from my Icom IC-2820H 2m/70cm FM mobile radio among its 3 levels (5, 15,
and 50W) when working AO-85. With all of these radios, my original comments
about the KG-UV9D and being able to work AO-85 when the satellite was above
20 degrees elevation appear to be true for all of these radios when used at
the 5-watt transmit power level.

I still plan on finding my IC-W32A and DJ-G7T to try with this satellite,
as well as trying two-radio combinations. As I try other radios, I'll post
my findings here. If anyone else is trying different radios with AO-85,
especially HTs (or other radios with low transmitter power levels), please
post your findings to this list. The AMSAT-BB archives are open to the
public, and searchable via search engines.

73!
