Hi everyone,
Firstly, thank you to the many people who have helped me over the last few days with getting started on the sats, you have all been very helpful.
I have now worked all the current satellites, including AO-07 and managed to get the doppler shift sorted out with Satpc32.
However, today I had a problem hearing both FO-29 and AO-52 - both were good passes. We had some very bad weather here in the UK so I was
wondering if the cloud cover can affect the up/downlink.

Hi Peter,
Congrats on working all the satellites - a very dedicated effort!
Weather shouldn't be much of a factor for VHF and UHF communication; it's not until you get into the microwaves that I have had trouble, and even with the AO-40 (RIP) 2.4 ghz downlink it wasn't too noticeable. Foliage is also a factor there, and somewhat for UHF; were you aiming through any big trees?
Most of the variation from one pass to another comes from the somewhat random orientation of the satellite's antennas compared to where the planet is, and the polarization of both station's antennas. Do you have linear or circularly polarized antennas?
