I believe people don't homebrew their radios for the same reason they don't build their own cars: While it can be done, and some people do, it is not cost-effective. Many decades ago you could homebr

-- ORIGINAL MESSAGE --(may be snipped) REPLY: The most cost effective approach to ham radio is to buy quality used equipment. If one buys the really good stuff, one can almost always resell it later
-- ORIGINAL MESSAGE --(may be snipped) REPLY: That capability is already here. Check out the FlexRadio 6000 series. I bought a 6300 (the low end model) about a year ago mostly out of curiosity. I wil
It occurs to me that one could have some fun and make a few bucks homebrewing coax cable assemblies. I would suggest using crimp style PL-259 connectors and making up a variety of lengths. You cold s
-- ORIGINAL MESSAGE --(may be snipped) REPLY: Same with the marine environment. For some reason, hams seem to prefer soldered over crimped, but if properly done, you can try to pull apart a crimped c

I'm glad your meter is reading correctly now, but one question remains: Why did it read wrong in the first place? From your description it seems like the meter circuit was designed wrong by Alpha in
That still doesn't explain the original error. I see two possibilities: 1. Alpha designed it wrong in the first place. or 2/ Some component changed value. So, which was it? Or was it something else?
I don't have the 70x schematic before me, but if it is like most modern amps, ground is not B-. HV should be measured from B+ to B-. not from, B+ to ground. Check your schematic. The difference is no
