I did a little Googlewhacking, and found that places like the UPS Store and Staples frequently have 3d printing services these days. But if you can't find one nearby, there are online services that wi

I have a similar vernier on the variable capacitor of my magnetic loop. Works like a champ. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P

I like the idea of the tube based xcvr. I've never built one, though I do have an FT-101 upstairs that I want to recap, retube, and neutralize. There's something wonky in the thing...when it has been

4SQRP does not control the structure of that menu, except by enabling or disabling features. A store link is not a feature they can enable, as they neither created nor control Groups.io. That is a thi

There's a guy I've bought from on Etsy (I got his SlinkTenna) who makes tiny keychain transmitters, complete with a little straight-key-esque button for tapping out code. It's basically an oscillator

Just my 2 cents' worth... The site is up. It's connecting. But there's nothing THERE. The homepage is blank, or some other failure is happening. I noticed that my own site updated PHP and Wordpress re

One thing that might be affecting regeneration is the "gimmick" capacitor C12. You might need more twists or fewer twists. I found it really changes the regeneration level a LOT. -=-=-=-=-=-=-=-=- 73,

There's also this one at Mike's: https://www.mikeselectronicparts.com/product/variable-capacitor-266pf/ It's used in this small transmitting loop: https://k1fm.us/2015/07/k1fm-mini-magnetic-loop-2-0/

I bought four from this source: https://www.ebay.com/itm/Dual-Gang-AM-FM-Variable-Capacitor-266pF-X-2-and-20pF-X-2-500pF-Total/113059337104 They're your typical AM/FM radio devices. I found a small tr

I could hear activity, but couldn't get enough past the noise to get even a single call sign. So I just listened for a while, trying to pick things out. -=-=-=-=-=-=-=-=- 73, Gwen, NG3P

Perhaps our British members might be able to verify if this is how the BBC's roving radio detection vans would locate people who hadn't paid their radio license fees? I've seen pictures of these vans,

Welcome, Pam! Hope to work you on the air someday! 73, Gwen, NG3P

From the consensus here, I think I'll make myself another full-sized W3EDP End-fed and try that next time I go operate at the park. It'll have to be when the parks are actually OPEN again, as the rece

It's interesting that you mention W3EDP antennas, Joshua. I have one as my main wire on my home station right now. I love the design, and it seems to work really well for me. I haven't used one portab

I made a simple linked dipole for 40/30/20 that deploys easily and mostly doesn't need any additional tuning. I have it set to the CW portion of the bands, so if I'm up on the top end of the phone por

Don, I haven't tried using my Ozark Patrol with a separate TX because a) I didn't think of that, and b) I don't have a separate TX that isn't also an RX! Maybe I'll try it if I build the Michigan Migh

I use the Talentcell 8300mAh 12/9/5v battery pack, Richard. I got it from Amazon here: https://www.amazon.com/gp/product/B01337QXMA There's also an 11000mAh pack available on that page that I've been

There's a lot of good books on electronics, many of which focus on RF circuits, but here's the list from my own library: The Art of Electronics, by Paul Horowitz. This one is very pricy, but very comp

I did try to check in on 40m, but could just BARELY hear someone. I think it was net control, so I sent my call a couple of times when things went quiet. I didn't hear my call coming back, then things

My experience is that the antenna tuning can affect the sidetone for some reason. Gwen, NG3P
