Jimmy, you might take a look at Digikey for parts.? I actually prefer Mouser myself but have been ordering from Digikey the last several orders simply because I can send them a check or money order

Last week I shipped a small I think 5 x 7 padded envelope to Las Vegas and if I remember correctly I paid $3.85 for the postage. Not bad. I like Chuck's idea of sharing parts. In my case it is very

Chuck, Let us know what they charge for shipping using that envelope. I took one to the post office a few months back to ship a couple of 3 pin Molex KK type flat connectors to someone. The connectors

Michael, Another option There are kits available for zero beat indicators. It just lights an LED when the signal has a certain pitch. I used WB3AAL's K6XX zero beat indicator kit in most of my QRP

Hi Jim, after I am back from vacation and the head is clear again, I followed first of all your hint. To my shame I have to admit that I made a mistake here. Sorry! I use a switchable probe 1x/10x on

Just to fill in some numbers from a different perspective. In Canada, I could order the envelopes Chuck posted a link to, shipping would be $14.00 USD to Canada - in CDN $15.69 for the envelopes and

No, I have not.? I have used the flat head screws that you countersink the hole and the head is flat with the surface, but I've gotten to the point that the bottom is out of view, so don't work on

Hi Chuck, Have you ever used press fit or other standoffs so that the ugly screws don't protrude through the bottom of the case? Such as these: https://www.pemnet.com/fastening-products/standoffs/

Excellent point! If they can hear me I don't want to keep jumping around. Funny thing, RIT was a difficult concept for me to grasp until I used it with my 40A. Granted the concept is simple, but for

And just remember, if he then comes back on a new freq, don’t retune, use your RIT. 73, Gary WB6OGD

Thanks Nick. This is pretty much what I have been doing, both tuning for max signal as well as trying to match the caller's pitch to something that is close to my sidetone. Even by keying on a clear

With rigs like the NC-40A which have "single-signal" CW reception due to a reasonably sharp IF filter, you can more or less tune for the strongest signal and you'll be close. If you know the amount of

All this talk of core memory almost makes me want to haul out the old Data General Nova that is tucked away in the basement and see if it still works. 73 Paul VA6PW

Hi Chuck, LTspice is something you can never fully learn, which I guess is good. Same goes for magnetics. The first unit of the nuclear power plant where I worked had core memory in its plant

I'm obviously showing how green I am, oh well. Many folks here have experience with the 40A but I'm just now starting to use mine. I don't know how to zero-beat without causing interference. There is

Nick, Thanks much, something I'm doing for the mental exercise. That did what's needed for the model to do something. I hadn't tried to do anything like that. The circuits supposed to amplify the

Hill, The same is available corewise on DIZ'site. Under toroids. However my experience is the AL value specified is not tallying with 10 uniform turns. What i do is derive Al from 10turn same, use it

I use the non-machinable forever "Butterfly" stamps all the time ($.70). A second oZ is an additional $.14. But beware with those and large envelopes ("flats"), it MUST be reasonably flat (SD card OK,

My local Dollar Store has them. 73! Mark KA6WKE Website: https://www.ka6wke.net Live Stream: https://www.ka6wke.net/live-stream YouTube Live!: https://bit.ly/bench-therapy-live Author: 4NEC2 The

I'm in a line of work where my time is easily my most precious resource (not to mention my kids are also young enough to need near-constant attention). So, for now it's not money or space (as long as
