Looks pretty interesting…a Raspberry Pi “hat” that turns it into a full SDR (transmit and receive) for about $150 + cost of the Pi. Anyone out there have

Holy smokes...what a mess! It's hard to figure out what Bylaw 46 means, much less what it refers to. Seems like the ARRL has way too many attorneys and has lost its way from a moral perspective. That

I just posted my first design at Thingiverse. End wire insulator ( https://www.thingiverse.com/thing:6335858 ) It seems to be public, though I had some issues with Thingiverse telling me it hadn't

Thanks Jed, yeah I'm pretty sure my approach is not part of the NEC, nor is it to code, although that being said, it's working really well, particularly since I'm using a circuit that isn't used for

Jed, you raised some good points. For my 240 V outlet I removed the thermostat used by my baseboard heater and simply replaced it with a 240V receptacle. I never used that heater anyway and it is easy

That's cool. Although the std. adage among hams is that a better antenna is worth more than wattage, more wattage doesn't hurt either. Kudos for diving into new territory as well. Don't quote me, but

Hi all, I just posted a lengthy blog about my experiences with operating QRO (high power) using linear amps. Over the past three months I've had the pleasure of playing with three different amps: an

All you QRP guys should enjoy this. https://www.youtube.com/watch?v=_-smYG_iQ40 K8MRD teams up with a couple hams and BioEnno to do 1000W on POTA. "You're 20 over in Illinois."

My mantra for years regarding HF ham communications-, If you have a radio with 100w ouput and you cannot get satisifed? - you need a better antenna. bud -- bud N0IA

Sounds like you've got that antenna pretty well dialed in. That is a lot of linear space. Reminds me of a SOTA activation I did a couple of years ago up on Mt Evans, which is naturally a busy place,
