Tim, You probably moved the wire that was shorting the mic element. Regardless, your are welcome and glad it is working. Now have some more fun operating! 73 Evan AC9TU

Well...you know how sometimes in the course of troubleshooting a problem either you inadvertently fix it, or realize that somehow it wasn't broken to begin with? I'm now getting TX audio as expected.

#ssb #v5 #tx

Tim, I got down to my shack, opened a v4 that I have (the v5 is in a more difficult case to fiddle with), and took some measurements. 1 - The resistance from the Audio connector side of R60 to the ele

#ssb #v5 #tx

Reed, The v5 does not come with a Baofeng mic, It is up to the builder to supply housing for the provided element and switch. The LED, and resistor are not included, so there is not a voltage divider

You might also try touching the "hot" microphone lead while listening on the TS-590 while transmitting. Itt will introduce transmit noise heard on the 590 and prove that the mic audio circuit is funct

#ssb #v5 #tx

Oh, looks like I left out C60 in my drawing (between MIC and the 1.93V measurement), but I don't think that changes any of the results. Reed

#ssb #v5 #tx

Attached is the voltage measurements I get when transmitting on my v6. I think this circuit is the same as on v5, but some label numbers might be different. Reed

#ssb #v5 #tx

Tim, I am guessing that since you say you get 12V means that the mic element is not connected. The voltage should drop a bit when the mic is connected on TX. If what I am saying is correct then open a

#ssb #v5 #tx

Thanks, Evan, I'm getting closer. I did in fact verify that I have +12v (or so) into the mic element when PTT is held. I thought that bias was there all the time, but your explanation covers that. (I'

#ssb #v5 #tx

Tim, It comes from the TX voltage (only there when transmitting) through R66 (220 ohms) and R60 (4.7 K ohms) to the "audio" connector on the mainboard and then is wired to the tip connection of the 3.

#ssb #v5 #tx

Thanks gents SSB receive is good. Seems to be very well on frequency, received audio is good, sensitivity seems pretty decent. I did the BFO alignment using the tool, and it came out about as expected

#ssb #v5 #tx

Tim, First off is the answer to Reed's question. That will tell us if the SSB filter and the rest of the rig is aligned, as it is common for both transmit and receive. Another test would be to verify

#ssb #v5 #tx

Does RX of SSB come in well, too? Or just CW? Reed

#ssb #v5 #tx

I'm ironing out the kinks and my v5 is coming together. If I can knock this one out then I'll be ready to go out and do some operating! My TX is good and strong on CW. Waveform seems nicely shaped (to

Dave, AD0B, Actually I only heard you calling ko4bsw, I threw out a couple of CQ’s but didn’t get any replies. Id be happy to try another uBitx net 73 Mick VA3EPM

Mick VA3EPM I never heard any call signs. Personally I would like to have a uBITX net again.

#calibration #v6 #ssb

I found that I did need to go with an amplified mic for my ubitx. I bought : https://www.amazon.com/Amplified-Loud-Power-Microphone-Radios/dp/B0077PS0UI. I adjusted the volume on the mic to around 4 o

Thank you everyone for reaching out and calling me this morning—I heard many of you. I think my feedline and or antenna are currently the issue. I’m going to keep working at this and will reach out ag

John, Sent you a PM with contact info. Happy to work with you live - I think we are near enough that we should be able to work each other. 73, Dean KK4DAS

You can check dc crrent while shouting ìnto MIC. Once ptt is pressed current would increase by another 200mA. As you shout into mic currentvwould go up to 2amps or little higher. This gives a clue , w
