TD, I bought a DIY 70Watt amp on eBay. I have had a number of issues, so do not recommend it. I have since gone into other things, so have not gone back to find a good amp. Sorry I can only provide th

The hfpacker amp is well regarded and well supported. https://groups.io/g/hfprojects/messages?expanded=1 It is also quite a bit more expensive than the ebay kits. Many people have trouble getting the

hello all, I have an uBITX v4, I didn't mount the microphone connector, and it's QRP. Interesting the option of installing a PA at the exit, as it is sometimes necessary to use it. Do not forget to us

Just snoop on Ebay. Granted you'll need to add filtering, be cautious setting bias voltages, and add a heat sink... but that's what makes it fun!

Anyone?

I have the uBitx v6 and would like to add a linear amplifier for voice/phone operation. Can you guys recommend either a kit or assembled amplifier? Thanks TD
