Hi,
Yesterday evening I get hands on the tools and eyes on the gear, and
manage to deduce a procedure to adjust the sensitivity of my RX rig...
This was great, just with a Digital Multimeter measuring the noise level
at the RSSI on the FI IC of the radio I squeezed the sensitivity of the

Good Day all,
After a few years hiatis, I am contemplating getting back on the
birds. Because I currently live in an apartment, I plan on starting
the easy route using an arrow antenna. My question is, since I sold
my last HT about a decade ago, what is recommended for the current
models of HTs
There is only one currently operable FM satellite, and many of the sats due to
be launched this year are transponders or FM/DSB repeaters.
My suggestion would be to find a Yaesu 817 to get a toe into transponders, and
add -any- UHF receiver for full duplex FM. The little Baofeng UV3s are like

Is Full Duplex really required or just nice to have? Currently my setup
(which doesn't include an antenna at the moment due to storms) is a Yaesu
FT-790(uhf) and FT-290(vhf). Both do FM and SSB at about 25 watts. I've
used to use my 290 for the old RS-12/13 and RS-15 birds along with my

Someone on the moonbounce reflector crunched the numbers and came up
with a path loss figure something like 51dB worse than EME, if I
recall. The small cross section area was the killer.
Still, nothing ventured,

Well from the original post:
The Goldstone 70M dish will be running MAX QRO with 435 kW.
That ought to be enough for EAE. H. CQ asteroid, CQ asteroid!
There's your 51+ dB! :D Slightly outside amateur power levels or the
antennas

I wonder if they considered that it may be significantly more reflective?
I can't see it being more than 15-20db to get from the moon's
reflectivity to a perfect reflector. Still, every bit helps. :)

What frequency do they use to ping space rocks? Do they use different
frequencies when they are pretty certain if it is rock, metal or ice and
dirt?

Hi!
I will have an AMSAT table at the Superstition Amateur Radio
Club's annual hamfest in Mesa, Arizona, on Saturday (9
February 2013) morning. This hamfest was supposed to take
place in early December, but was postponed due to scheduling
conflicts. The hamfest will be at the usual location,
It's not mandatory, but it's good practice, especially on FM where things get
crowded and only one gets through. On transponders it is good to gauge your
signal strength (especially on fragile sats like AO7), and to be able to match
uplink and downlink for Doppler. However, with caveats and a

Short notice but I will try to be on the next FO29 pass over Hawaii
