That last image shows my QSL card next to my Knight-Kit T-60 which was built on April 6, 7 1963 by American WW2 hero Jacob Beser, W3NOD and his son, Eric Beser, KN3UHF. You can read all about Lt Beser

Here is the power supply I ordered. Should be safe for most things! https://www.amazon.com/dp/B09LQGGGW7?psc=1&smid=A435SHMBG5KTO&ref_=chk_typ_imgToDp

Thank you John & John. Glad to see my efforts were not in vain. I have over a dozen groups.io accounts, and seem to get my messages repeated back to me only on some of them. For QRPLabs, I receive

Hi Evan, thank you so much for your reply. Am 15.01.24 um 00:56 schrieb Evan Hand: It's a REV 2 (without the suggest diode mod yet) and I measure 2.47 Volts powered up in "receive" mode on Pin 9 of

Bryan, The manual says a) A 220K resistor at R4 (this resistor is not supplied in the kit, OR b) A jumper wire in the position shown, and NO R4. The picture shows 4 holes. Looks like the jumper

I may have answered my own question. I'm wondering if the 220k resistor needs to bridge over two holes instead of one. I have one lead of the R4 the resistor in the top hole where the jumper was and

I replied to a couple of messages here, but did not see my post. Is there a place to enable self-posts by logging into groups.io, or is this set up as an individual group option? Given recent

There is a Adjustable voltage/current limit board on AliExpress for about $10 ( 0-30v 0-3A ) search for Nuitool Store or.. 0-30v 2mA-3A Cntinuously Adjustable Current Limiting Protection DC

Been away for a few days but having a look at the new heatsink, adding machine screws is easily accomplished. 1) A hole can be drilled into the heat sink's center to compress it with a thin layer of

I echo everthing Howard says in his mail. Although I run some bucks here for various bits of kit, for all building and testing I use a linear in exactly the way Howard describes. Cerianly not all, but

You mean QS SEX???

My 1300Z session: First on 30m (using my QCX Classic 20m) I worked the "regulars" PA0CMU, DK3UW and OK2BQN, then ... nothing. With some trouble I could get through the pile up of a SOTA station

I'm retired! Plenty of time! 72 / 73, Bill, N4QA/4

My current limited power supply is of little use.? When a short occurs there is a high current pulse before limiting kicks in.? I believe my supply, and maybe most, have a large filter capacitor

I was not opposed to the clocks brightness witj the jumper installed but decided to add the 220k resistor at R4. there are three holes at R4 reference designator. the jumper appears to be installed

John, When I was first starting up, I used a couple 1W resistors in parallel, and a variable power supply. I started at 7v and two 56ohm resistors (parallel=28ohm) for my 12v QMX build. Ohm's law

a current limiting PSU should be the second item in your toolbox after a multimeter. There are plenty of designs around and can be made quite cheaply. I would recommend a linear PSU (NOT DIGITAL) I

Thanks Donald & Steve. You've reminded me of my earlier message in this forum re:infrequent USB disconnection, which may have also been caused by stray RF, due to the close proximity between my EFHW
