Are there any working satellites with down links in the HF band of frequencies? I have looked on the amsat site and others and they all seemed to be "none Operational" at the moment.
Thanks in advance for any replies.
Regards.

Trev,

Not at this time.  There have been some in the past, particularly the old Russian RS-birds, but nothing up now, and so far as I know, nothing is planned.  However, given the constant interest, we may yet have another in the future.

Alan,
Many thanks for taking the time to reply. A bit disappointing but I have just acquired my first vhf/uhf handy after being a ham for over 25 years so I am looking forward to listening and maybe working through some of the LEO sats. That is after I have read the mind boggling instruction manual. Getting a bit long in the tooth. HI
Again many thanks.

Actually, doesn't AO-7 have a mode with downlink in the 29 MHz range?  Mode A

Alternates every other day between Mode A and Mode B

Hi Mark,
Thanks for the info, nice of you to take the time.
Yes, you are right about OA-7 heard it this morning about 1050am but it sounds like it is in the last throws.
Signal report was 559, if indeed if it was OA-7 I was listening to. It was just a broken carrier, could have been sending e m t t.  I think that was a stretch of my imagination but it did appear on 295020 at the right time build in strength then fade away. So I thank you for helping me hear my first sat with your info.
