Radioddity has a built, ready to plug-n-chug LPF available for their 100W amp that is a fraction of the size of the full kit V6. Costs about $100 if memory serves me correctly. However, if you wanted

Ken, Any chance you might make the design files available (or even just the gerbers) for that LPF? Looks pretty nice! 73 Mark AJ6CU

Hi Ken, I like your filter board! I've had the "it would be cool if the µBITX could change bands on the amp" thought in my head for a while but haven't gotten farther than that. Nice work! Leonard - y

Hi, It does look nice for single band use as it looks like Sunil has added a spot for a single LPF on the amp board. Probably it's set up for 10m now, but you could choose a lower band as desired. 73,

The bare board should be available on www.amateurradiokits.in in a few days. A kit with most of the components will be available later. 50V is too high - 28V is the absolute max. It requires at least

Leonard - your manual was among the best guides that I found while researching and eventually building the amp. I think I've still got a browser tab opened to it on my shack computer. Kudos & 73, Ken

Hi Jim, Gotcha - that makes a lot of sense. Or if I only want 100-150 watts out I could just use the 2 pill - and leave the Collins for my benchtop station. Thank you, Dean KK4DAS

Dean, your 30L-1 likes to see 50 watts or more to start to make good power. While it should amplify the output from a ubitx, it's a kilowatt-class amp with only 10 or 12 dB gain. So with the nominal 1

That's great, that it worked so well. I know I need to put a beefier relay in to switch the amp to TX. I know I need to put a diode across the relay coil to protect the uBITx I'm looking fir advice /

Last year I fed my BitX40 into a homebrew grounded grid sweep tube amp.(which I think is more boat-anchorish than Collins, no offence.) This amp has spent nearly 20 years sitting in a shed in Hawaii,
