The easy way of tinning self fluxing enamel is to apply iron tip and fresh cored solder to the cut end of the wire. The solder reacts with the exposed copper, the coating then melts back and the

I hope that later that Han's gives an idea of the case dimensions and what volume is taken up with the internal circuitry in the full all band version. Why? just to get an idea if there is enough

Personally, I would be a fan of keeping it simple.? I'm no RF engineer, but it seems that more complexity will add more cost and more things to break. I am REALLY excited about this radio.? I think

Hi Alison, You are quite correct, *I omitted to name every radio that had this feature*. ?I'll throw in another there was a sota / mountain top 'lite' design that announced frequency via a Morse

Simon, I suspect John needs to tell us whether he obeyed "2) Program only the provided .hex file (see above); do not change the Fuse settings, or other memories (e.g. EEPROM)" 73 Alan G4ZFQ

Hans, Please let me know if the instructions need updating. 73 Simon VK3ELH

A new chat has been created: I attempted to upgrade the firmware on my QCX 20m from 1.00e to 1.00f.? I am using the instructions from "How to update the firmware on the QCX using an arduino uno and

Hi, Does anyone know of a source for a cable to use as an extender for the LCD.? I am having problems with my kit and want to be able to probe underneath the LCD but it's in the way. Thanks 73

Hi all,?I was bored this afternoon…one of the few days since retiring last December.?So I played with the U3S and set up a message on the U3S that looks like a sine wave on page 38 of the

Alan, You must have missed the work KB1OIQ did to take Raduino/uBitx and add voice out plus low vision or no vision aids to that. Allison

Is there a proven way to implement a 4-line LCD display on the U3s? Thanks, Tom? KJ6MKI

Paul, I have more ways to do it if that were an interest now. I have two up converters and plenty of ways to generat RF power down that low. Just the usual problem of 24 hour days and other things I

Figured it out, first time kit builder excitement ... triple checked part placements and had L1 in L3 ... bingo .... working now? Thanks

Hi Allison, If you just want to run a beacon then a U3S will be fine and there is no need for a SSB transceiver. But if you want to make two way QSOs the situation is different. Digital modes allow
