Subject: [Amps] Old Moto RF Decks
I have some of the old Motorola (Micor?) RF decks. I have both the VHF & UHF
types. The 2 meter is running a pair of the 8560A tubes. I can't recall the
single tube in the UHF decks.
The question being is there any market for these things now-a-days? I had
intended to build up a PS for them eventually. But, got hooked on playing with
SSHPAs.

Hi Paul and the group,
I have several of the single tube (high 2m band), dual tube (high 2m band),
dual tube (6m band) RF decks. I created a PS to power the RF decks and
converted a couple of the single tube and dual tube units to 2 meters. The
dual tube units put out about 750 Watts with about 5 watts drive. The single
tube units will get you about 400 Watts with 3 Watts drive. I had a UHF unit
(single tube), but used it for spare parts to fix others.
I liked the fact that I could run 700+ watts on 2m SSB with no fan noise. Just
built it into a rack with the heat sinks sticking out the back...
Tubes are by far the hardest to get a hold of now, for me at least. Maybe I'm
too cheap......
