Hello All,
I heard something interesting earlier today while monitoring an AO-7 pass
above my QTH at around 23:30Z. The mode B (U/V) transponder basically went
dead, and I heard a very odd buzzing sound in about the centre of the
passband, with no activity anywhere else in the passband. Not a typical
FMing sound, but something more akin to auroral buzzing, like on 6 metres.
We have had some great visible auroral shows at my latitude lately (57
degrees north), and I wonder if the solar wind causing the aurora may have
had an effect on old AO-7. Did anyone else hear this? Any thoughts on what
was happening? I see from the live Oscar update web page that Russian Hams
reported normal mode B operation subsequent to my observations.
As an aside, after repair of an intermittent in the UHF finals of my ICOM
820H and replacement of the N connector, I am fully QRV again on the birds,
and look forward to giving out grid DO16 when able.
73 to all,
Randy, VE6RGU

Good morning all and 73/
I know this is a bit off topic (maybe way off topic) but I'm sure that many
of you regularly use UHF. I have been looking for a source of a UHF LINEAR
amplifier but they seem to be extremely difficult to find. I can find
repeater amps and ATV amps (FM) but haven't been able to find any that
specify that they are linear. I'm not looking for legal limit just
100-200watts. Any help would be appreciated.

One source I am aware of is RM Italy. Here is a link to a unit that
might suit your needs:
