I forgot to mention that it worked before the upgrade and is wired according to the hfsignals instructions/schematic. Thanks again. Marco - KG5PRT

Hello Ian, I have just upgraded to v.30 and all the settings and fixes are much appreciated. I have a problem, though. I am unable to use the keyer. It does nothing. Is there a hardware mod that

Two problems that may affect use of a Pi-ZERO inside the uBITX. First it will have to be shielded to minimize radiation of spurious signals that might detract from typical BITX quiet background and

I need yet another project like I need a hole in my head! :) The my top mod PCB is something I should get working first, but I may later try doing a simple rpizerow to teensy3.2 adapter or something.

Tim AB0WR No modulation involved. The operation is as a switch between ON and almost OFF. Gain of the two BJTs makes it operate quickly and drop the output voltage to the point where the current

Surfboards (digikey) are your friends. I use them all the time. Pretty expensive but for single applications nothing beats them for using all kinds of smt parts. tim ab0wr "Ken KM4NFQ"

JUST SAY NOOOOOO!!!!!!!!!!!!! Rather than modulating your signal, why not just use a noise bridge to tune up your antenna WITH OUT TRANSMITTING!!!! Check this out....

It would seem to me that this type of operation is actually AM modulation of final. When you limit the current flow in an FET that is very similar to plate modulation in a vacuum tube. It certainly

I'm a bit busy right now. Can I ignore it later? :)

I haven’t measured it ... but machine pin headers may work? They are pretty low profile. M

True. Raj. But it is easy enough to cable the display. This has been discussed before on the forum. It means a little bit different way of mounting the rig. And the benefit of a removable nano

I had trouble with k3 relay not switching back to receive. Couldn’t find a replacement Luckily re-solder seemed to solve the problem. I would like to find a replacement just in case. Bob W5rkm

Gordon & Cesar, The display will not fit into socket if the Nano is mounted on sockets! Raj

50K audio taper will work and you might fine CW side tone loud. Raj

Cesar: It is likely that you blew out the nano. The most sensitive part of the nano (and most of the arduino clones) is the USB interface (CH340 or CP2102 or ATMega32U). IF that goes, even though

Check out these on eBay cost me a just under ?2 each I got 3 of them just not tested yet chris
