SG Labs 3400MHz Txvtr

Post by VK3APW » Tue Aug 13, 2019 7:17 pm

Hi All,
just received a SG Labs 3400MHz txvtr. From the factory, it will work 3398, with a 430MHz IF.
It seems possible to reprogram the LO, to work with a 435MHz, which I will attempt in the next few days.
Published Specs, are pretty much as per the 2400 txvtr; from my limited testing so far, on the bench, it appears to exceed expectations. Power out, ( on my unit ) with 2W of IF drive, gives slightly over 4W @ 3398, and dead on 4W @ 3400MHz.
Rx, out of the box, conversion gain was set at 8dB ( is adjustable ) and the difference in performance between 3398 & 3400 is too close to call.
The lead time at the moment for these, is about 6 weeks, so if you order one, be patient, it will arrive :D
Should be good for a portable or home station.

Regards

Peter vk3apw
