Does anyone have any info on this unit. I picked up a used one from a local
hamfest and wanted to give it a try for V/S mode, but I have no data on the
unit (it's a masthead mount).I looked on the SSB site but can't see
anything.
Any help much appreciated.
Regards
Robin W7YED

All:
N3SH will be operating all possible birds on Field Day from EN90.
Between passes, we'll be seeing what we can scare up on 2m 70cm, and
possibly 1296.
Question: Anybody else in vicinity of SW PA going to be up? If so, any
digital modes (wsjt, psk31) on tap?
(Trying to decide whether or not to make the effort to load them all on
the laptop.)
Good luck to all on Field day and have fun!
Thanks & 73,
Jim

The old UEK-2000 downconverter was a good 2.4 Gc unit. Did you get
the entire unit including the three turn helix and dish? They were
a single unit originally. The green box behind the helix reflector
contained the downconverter, 2400 to 144 MHz, thus 2401 to 145 MHz.
Power was 13.5 VDC fed from one of the two RG 141 coax cables and
terminated in CENTER panel connector which served as a mount for the
entire feed/converter. The other RG 141 coax was the 2 M IF down coax
and was the type N connector to the RIGHT of center when the mounting
bracket was toward the observer. A double male N adapter connected the
helix to the converter box to the left. Does that give you a start??

Robin,
From memory the UEK-2000 was the only mode-s converter that has a
sufficiently low enough NF and gain not to require a preamp for hearing
AO-40. That means is should work fantastically for AO-51. You should
mount it directly to the s-band antenna and not at the end of the coax feed
into your shack, as that will seriously degrade the noise figure and
performance of it.
Used with a small 3-turn helix, patch antenna, or small corner reflector
should suffice.
73's,
