Knocked this up a while ago in a quiet hour at work. Rebuilt today to reduce flex away from the contact points, as it felt far too floppy, and installed the front screw+nuts as a stop to further tighten up the general feel and behaviour. Much nicer already, feels crisp.
This was donated to me by a member of the radio club I attend, NZART Branch 02.
I was shown a single, token photo and told it was a cabinet with “transformers and stuff” inside and accepted it, figuring I could get some trafos and chokes (as though I need them -_-) and scrap the cab but it turned out to be a ‘working’, supposedly 400W linear amp. The ‘documentation’ suggests it can be used from 80 to 10 metres.
I’ve been advised to test thoroughly and clean it very well before attempting to power it up, but that it should be in mostly working condition. I don’t really know what I’m doing but it looks simple enough to tackle methodically and with care. 1500volt B+ probably isn’t ideal for a noob’s first foray into hollow-state, but I’ll get a better idea of the trouble I’m in over the next few days when I bring the individual racks into the house to photograph them. Should be fun.
I was looking around for QRP kits/designs and found this. It is a most excellent write-up… style+substance, 11/10. A guided journey through one dude’s experience makin little radios. WA0ITP @ QRPARCI.org
After owning this domain for around 8 years now, and making only a token effort to put content up on it, I’ve finally found the motivation to push that One-Click-Install button and get WordPress on here.
I’m some sort of amateur wanna-be engineer hobbyist type, so my hobbies involve planning cool stuff to build, buying parts, and then marathon-watching TV shows instead. This blog is to detail my thoughts regarding some stuff I like to consider doing in the hope that some other hobbyists somewhere find my perspectives on things valuable.
