No luck unfortunately. Too many power supplies and cable runs next to each other; I will need more extreme measures. @hamchallenge #HamChallenge HC10
March 02, 2026 18:35 UTCclaycoug@mastodon.hams.social3Success!The relay hat on my pi4 was causing interference with TM-v71a making 2M almost unusable. I repurposed the pi4 to replace the wyse pc on my allstar node fixed the issues. When i rebuild the old pi4 system with 12V relays I will put the system in medal box under my astron 75.

March 10, 2026 21:46 UTCDF1CN@social.darc.de4Success!@hamchallenge I accidentally found a source of interference. I was scrolling over the bands when I noticed that that 80m was full of QRM that wasn't there a gew days ago. I was looking up 80m foxhunt equipment when I heard the tv turning of and suddenly the QRM was gone. So I grabbed an AC filter and plugged the TV into it. It seems to help a bit (but not much). Still I count that as a success. HC10S #hamchallenge
