Subject: [VHFcontesting] Tohtsu CZX3500 Relays F.S.
Hi all, I sent the message below to the reflector but the images made it too
big. I can send pics if you want.

Hi all, I have 2 brand new Tohtsu CZX3500 type N relays with 12 volt coils.
These are useable to 4gHz and the manufacturer says they will handle nearly a
kilowatt at 432MHz with great isolation and low VSWR and insertion loss. These
relays were used in the original Lunar-Link VHF amplifiers. Those amps ran the
legal limit, so the numbers on the data sheet below are conservative!
Here's a link to the full Tohtsu datasheet:

RF Parts and Henry radio get $180 for these. I'd like $120 each, plus shipping.
Preferred pay by PP friends and family.
