Has anyone tried a H11F3M for the AGC on the newer uBITX ??It's a Photo FET Optocoupler made by ON Semi and actually shows an application note with AGC use. You could drive it with the existing

Jerry, I've looked at the hycas setup before. The AGC detector isn't a lot different than what Don has used. The only difference is the use of a differential amplifier and a PNP AGC driver. There

What is the link to the assembly instructions you are using? Leonard

I use ethernet wire for breadboarding.

some of those headphones use litz wire....

For some reason I have not been getting any message from the group in my email.? I just checked my settings and all seems to be correct.? What happened???

You mentioned Winlink, so I assume you are using CAT control. Every time I've experienced this when using CAT, it was caused by RF getting into something. With my setup, whenever I run more than 2W on

The PTT pin at A3 of the Nano should go from zero volts DC during transmit to up around 5v during receive. Does it? If it is around 5v and still transmitting, what firmware are you using??

I would look at the PTT signal. If it is stuck on then the problem is in either the PTT hardware or software. Clark Martin KK6ISP

My ubitx will frequently stay in transmit. The only way to get it out is to transmit another time and return it to normal. Sometimes it takes several transmissions to get it back to receive. In the

Most of us in the forum have the rigs from hfsignals.com Do you have one of these from Sunil? ? ??https://app.box.com/s/6g5rj15kgpft1mqxkg7h/file/16782106213 Most of us have no idea what transmit

Ethernet cable is also good. Unwind the bundle of wires in the cable and then roll each on a flat surface with a 2x4. It will "unkink" and leave you with nice small diameter wires. I think this was

I printed mine out on with an inkjet printer on regular photo paper and then put some clear tape over it to preserve it. Dan, W2DLC

Shytron In order to provide help we would need to know a bit more about your problem. - Which model BITX do you have? - What test equipment do you have available? - What are the symptoms

A google for "w7zoi hycas" will show a well regarded AGC system. It gives nearly 60dB of gain when there's no AGC action, about 40 dB more than the uBitx 12mhz IF has. Lots of parts, but most are

I get most of my small diam wire by stripping it out of old TV sets or radios. Plenty of good stuff if you take the time to look. 73 Jim N6OTQ
