I've got one of those Uni-VFOs (and another one still in the paper bag, waiting to be soldered). I think it's a clever project and the small size, use of a pot for tuning, and configuration set by

Hello Albert, I built something like you're describing a number of years ago. I had some hamfest flea market crystals, 3rd OT, for 50.245 that I wanted to do something with. The receiver section was

Hey, Allison! That was a supremely minimalist self introduction! It's nice to have super-experienced folks lurking in the group. Welcome, Kirk, NT0ZRochester, MN My book, "Stealth Amateur Radio," is

This is my storage for leaded components. Trays are 30 x 42cm, 2.2 or 5cm inner depth. In the case of resistors, the classification is not comfortable, 6 values (e.g. 10 12 15 18 22 27) in the same

Configured for 40 meters as shown. Schematic attached. Features: 1. Triple tuned bandpass filter before mixer 2. 2SC3357 post mixer amp biased to 40mA 3. 6 pole crystal filter @ 12.288 MHz 4. Carrier

Albert, I used these modules for my aprs mobile trx and they are making life easier. You don’t have to deal with RF build and concrentrate only on firmware. The module is for VHF band called Dorji

I actually have a Greek transistorized PRC-6 and I will most likely be looking at that board for some ideas. I have never designed a PA section and will need to study up on that. Thanks for the idea.

A few years back, a company was selling PRC-6Ts. These were refurbished PRC6 WTs, that had a solid state module dropped in to replace the tubes. Far-fetched, but maybe you can find some PRC6 (or 6T)

Good afternoon gents. I have a project that I would like to work on and would appreciate some input. Most of the QRP stuff I see is HF related, and I was looking for ideas and resources for a VHF

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

Thanks for the info on the labels Chuck. -Albert KI4ORI

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

Looks great, Chuck! Does it work??? 73 Mike M. KU4QO [email protected]> wrote:

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
