I sent something from Kentucky to Michigan by USPS on a Thursday/Friday and was promised it would arrive the following Tuesday. Then the USPS tracking tool advised that because of the Corinavirus confusion, it would be delayed. It arrived the following Friday/Saturday. All things considered, delivery times may be bad but not unreasonable.
My uncle was a USPS mail sorter on a train between Knoxville and Cincinnati for many years. He once commented: "I don't know why people complain about the mail, where else in the world can you get a letter delivered for a penny a day?" Then he laughed.

Re: Last effort before it is scrapped.....
Changing antennas making it perform OK may indicate that you had high SWR on the other antenna/s. The RF could have caused feedback and received distortion. You may want to recheck the SWR on the other antenna/s.

Hi, Peter.
I'm sorry for the delayed response. Please don't take it as a lack of interest in helping.?
I added a 22-ohm resistor to the bias resistors recommended in the case of other transistor swaps, i.e. R87 in the pre-driver, etc. Without the schematic handy, I'm hesitant to name all three instances where this is done but it's essentially the same bias change as if 2N2222's had been swapped for the 3904's.?
Another user a while back suggested simply going parallel with the similar, now disused resistor next to it i.e.R88 for the same objective.? That is, shunting across the non-grounded side of R87 & R88 is the same as nailing a second resistor on top of R87 - and it's easier.? So, that's one way you can do the bias adjustment when replacing two 3904's with one 5109.
About those finals: Note that the motherboard has been Dremmeled out a little behind the finals, to make room for a heat sink arrangement inside a steel hard drive case. I messed up and also let out the magic smoke from the original finals besides. My de-soldering skills are terrible and I also have nerve damage affecting my hands, and so you're looking at a poor repair, there. It is not pretty.... the radio works, though. ?
Best of luck, Peter, and do feel free to write again if I can help.

Re: UBITX use with 144 MHz transverter
No problem... and I'm going to (when I get the chance) convert an
old BitX20 I built to 10m for use with one of those transverters.
I might mention that I've got one of those 144 boards and a 440
(pre-assembled) unit.? I found that the Transverter conversion was
slightly off - I'd suggest using a frequency counter and put a known
frequency CW signal into the transverter - and measure the output
frequency.? That way you know what the offset really is.? Then
whatever you get on the dial, will be what you transmit on 2.? If
you learn how to mod the programming - you can always go back and
make the display accurate to what is transmitted!
28.1 = 50.1, 144.1, and 432.1 on the transverters, plus or minus a
tiny bit.? The big thing is not to overpower the front end - if you
get a transverter with the power divider board (reduces the signal
to an appropriate level for the actual transverter board), make sure
you NEVER go more than 10w PEP, and if you run 5 (even 1), that's
great.? IMO, a BitX would be the ideal radio for one of those
(Ukrainian) transverters!
(You don't need or even want to get every milliwatt out of the
finals anyway.)

Hello, is it possible when I use the uBITX with a 28/144 Mhz
transverter to display instead of 28.300 the frequency of 144.300
for example. Thank you for my question which may be impossible.
Thank you so much.

Re: UBITX use with 144 MHz transverter
Michel
Changing the frequency display to accommodate?a transverter should? be rather easy.? Frequency display is already a calculated offset to? accommodate the IF frequency.? You would need another?calculation? to multiple the HF frequency display according to the transverter offset. Probably just one line of code.

Re: Last effort before it is scrapped.....
McRuss,
Is the audio problem on receive or transmit?
If on transmit, then the suggestions by Gordon are the first step.? Then go to the final BFO calibration in the 3 step process of Ashhar Farhan's video (see link below)
If on Recieve, then be sure to follow all three steps in the video.
Note: The reason for the three steps in the calibration process is that the first BFO setting is being set to allow for optimum zero beating.? You need the low-frequency response to hear the zero beat as you get closer to the correct frequency.? You then need to change that setting to optimize for normal audio.
Good luck!

Don¡¯t give up! It¡¯s a hobby! Intended for learning. ? Plenty of books and monographs out there to teach. ?The development environment is free

Re: #v6 mike jack replacement
#v6
Ralph,
What you describe to me seems more like a mike issue than the jack on the rig.? Regardless, the jack on the uBITX is a TRS (Tip Ring Sleeve) 3.5 mm jack.? The other term is a 3.5 mm stero jack.? this is not the same as the jack used on laptops and smartphones.? Those are TRRS, in other words, there are two rings.??The one other type of 3.5 mm jack is a mono jack with only tip and sleeve connections.
Here is a mouser part number that should fit the board.? Please verify, as I do not have a v6 to check if it is correct.
If you have an old TRS 3.5 mm plug, try plugging it into the jack and then short the sleeve (ground) and the ring connection.? If the transmitter keys, then the problem is in the mic or the mic plug.? Could be a broken wire in the mic cord.? If you have an ohmmeter, verify that the sleeve and ring have continuity when the PTT switch on the mic is pressed.? If not, then that is your problem.
Hope this helps,
