Gwen Nice to cross paths again. Be patient while you figure this rig out. The frequency display represents the missing carrier frequency on ssb. The frequency where transmit happens on cw will be

Roger, If you are in the U.S.A., I'll give you your money back, for the radio and the case. Donald, KB5PWL

As I mentioned in a previous email, there are issues with the documentation on hfsignals.com They do check the boards before shipping, but it is still possible to have trouble bringing them up. Most

Hi Gwen and all: Something about Americanisms (NZ English IS English, not quite so severely mangled): "started noodling about for signals": I take it "noodling" is investigating, i.e. using one's head

Thank you Jerry. I was very concerned about frying the Raduino because the board I received is quite different from the one on the site diagram. As I said, without the forum I would not have got that

I thought I blew out the PA 12v trace trying to tune it on 160m, but I guess I didn't. I think the 12v power connection was slightly intermittent on the board, possibly from a slightly loose

Hi ! My project is on the way and I should receive my ubitx maybe tomorrow. Anyway, I've built the battery pack : It's finally a 3S4P battery pack, from lithium 18650 cells. I didn't receive yet the

That video is dated Dec of 2016, right when they started shipping with the Raduino (and thus with L4 not installed). And at the very start of the video, Farhan states that the unit he is debugging has

Roger, have they supplied you the board with raduino? If so i humbly feel , no point in seekin alternate components. All the best Regards. Sarma vu3zmv

Jerry You are entitled to your opinion, I just don’t happen to agree with you. The video online reference that I was sent refers to those components being present. There are minimal connections to

Roger, L4 has not been stuffed on the Bitx40 since late 2016, when it first started shipping with the Raduino to replace the rather unstable analog VFO.? (If L4 were stuffed, the analog oscillator

As raduino has taken over vfo , perhaps they stopped mounting those 2 parts .

Hi Vic The video has helped a lot as I only needed the first minute to work out that the VFO is never going to oscillate as C93 and L4 are missing, per the picture below! I put the scope on Q7 and

+1 for Dean's (KK4DAS)? approach. (1) CAT control? USB cable drives both freq and TX/RX (PTT). (2) Audio patch cables drive the audio between laptop audio i/o and uBITX i/o. The simplicity and

As I recall, there have been reports of some of the small toroid leads being broken from rough shipping...seems like those reports were from the UK, too. These are great little radios and I have

Werner, I reread your post.? Since the RX audio is perfect, the hum could be coming from either the mic input or the power supply due to higher current draw on transmit. Do you get the hum with the

Hi Werner, It sounds to me like the problem could be the opposite, a ground loop where there shouldn't be one; maybe caused by the enclosure or standoffs touching something it shouldn't. Try to remove

Thanks Curt! -- 73! de KJ7EZN? ?Jim

Jim I had an old kenwood mic, using what I had. I cut the cord after I identified the stock wiring. Let's see you need 3 pins, audio, ptt and return. If you are doing homebrew case, consider what you

Thank you to all that have relied!Neil
