Re: KitsAndParts uni-VFO kit
Your job does look great Chuck! I wonder if you could do this in the kitchen oven? I've checked the temp before, it is right on. 73, Gary WB6OGD

Re: ADC 40 (and ADC 20) crystal filter info
Steve, Yes, the output from the G3URR testor is related to the crystal's Q. In my G3URR/W7ZOI measurement setup, I use a diode doubler on the output (from a G3URR article in the ARCI *QQ*) to a pair

Re: KitsAndParts uni-VFO kit
It's a certain kind of ridiculous how small those have become! Considering my semi-senior eyesight, I have done well with hot air removal and replacement of tiny ICs, but I haven't yet tried the

Here is my second pass at the skillet method.? I am a fast learner, gotta give me that. I'll do a video of the patented paste applicator.? We don't need no stinking syringe. No solder bridges ever

Re: The qrptech Samuel L Jackson and Jennifer Garner Effect
Thanks Chuck, The Vevor is the one I looked at. I can't imagine cutting .250 aluminum with it but should be OK for 1/16 or maybe even 1/8. I'll watch the video and I think there would be many ithers

Re: The qrptech Samuel L Jackson and Jennifer Garner Effect
btw, if you really like to live dangerously, you can cut PCB with a micro table saw like this proxxon i bought for other projects: https://www.proxxon.com/us/micromot/37006.php easier to make square
