I just grabbed that 70 watt kit. Waiting for a heat sync and would need to get some multi band filtering. I think I saw something on eBay I¡¯ll get. What are you using for filtering ?Curt?

I built the 70w version of that amplifier.? The instructions are pretty much just a schematic with a few mistakes on it but it's not very hard to figure out what goes where.? I made some initial contacts with it connected to my FT-817 and a 40m filter on the output.? A few people said that my audio was a little distorted.? After doing some searching online it's been suggested to increase the bias by 1v.? I have not tried that yet but the guy's reasoning sounded logical.? It's a fun little kit to build.

With the Bitx radios you would have to get just a little creative to trigger the TX/RX relay but that shouldn't be very difficult.
