That gives me some idea.? Your response is greatly?appreciated.

I don¡¯t know if all will go this way, but I ordered a uBIX v6 from Ashhar (HF Signals) on 22 Feb 2021, received notice of shipping via DHL on 23 Feb 2021 and had it in hand on 25 Feb 2021.? Way faster than I was expecting.? Just my experience.

They use excellent shipping resources. Its a long way from there to your qth. Also the pandemic is hitting them much much harder than many of us. I suggest trusting it will arrive, this ain't like in shipment within US or EU. If they have a tracking number
it would pretty much say it was shipped, and next thing we see is delivery. Oh to ND, wow probably a few days faster than getting to me in Central MD (-:

You might want to look at the data sheet for? the Texas Instrument LM567 IC.? This is actually primarily designed as a DTMF tone decoder, but seems to have a lot of other uses.? The web address is:
This will save the trouble of searching for it.? It's a .PDF file, and the IC is available in a standard DIP package.

Hi, All,
Just wondering...From the time you ordered the uBITX, how much time elapsed until you received the package?? Were you sent tracking information?
I didn't find a place on the website to add the funding for faster shipping, so I figured I could wait.? I certainly and not lacking things to do!? Hi.
If anyone could enlighten me, I would appreciate it.

Talk: Does price buy Performance or Satisfaction in an HF Transceiver?
Frank Howell K4FMH presents a fascinating insight into our modern HF rigs looking at their price, their performance as measured by Rob Sherwood and reviews on eham.net.
Do you get what you pay for??Are expensive transceivers really worth it?

Gerard, I put back-to-back diodes between pins 12 and 16 of the schematic (be careful as I have been told that does not agree with common pin numbering for the relay).? This is to protect Q90 from external RF sources while in receive mode.? Here is the K1 portion of the v6 schematic (all of the versions are the same in this area).  Unless you are asking about the kickback diode protection for the relay coil.? That is D7 above. 73 Evan AC9TU

Re: Best wishes to our friends in India
My wife and I have lost six people we knew and used to see regularly - directly due to COVID-19.? Students in my department lost parents and family members... unexpectedly because they were in good health and "not that old".? If I remember right, one (maybe more) lost both parents in a very short time due to COVID-19.
I'm glad that the vaccines are out and effective (especially for preventing deaths and serious cases).? I do wish that the vaccines and materials used to make them were more available to other countries, like India.? This is a global issue and we need to think globally in fighting it.? We can't think just about ourselves anymore (individually and as a community/state/nation)!? The ban on exporting the raw materials used to create the vaccine needs to stop!? (Likewise the destruction of materials and equipment meant to help fight it - as seen in news reports lately.)
IMO, Amateur Radio could help... keeping the spirits up of those trapped at home and helping to get information in and out of areas that have limited communications.? We should work to this end - focus on that idea.
I have been aware of the case loads and death tolls around the world.? We also should model good practices - wearing masks properly when in public.? (I rarely see people wearing them properly when going to the store - and many people refusing to wear them for political or religious reasons.)? If we can help keep people from spreading the disease, we will have done a good thing!

Re: radio will transmit CW but not voice
First, you have the wrong microphone.? The rig is designed for an electret type mike.
Second, connection to the mike is wrong.? Use the schematic to show how the mike should be connected.? If your transceiver is a uBITX,then use the uBITX schematic.
Being off-frequency indicates that alignment is needed.
Audio output level could have been damaged by a short in the output connection, but it might be worthwhile to try a different speaker first.? If the alignment is way off it can affect audio output because it places the signal outside the crystal filter..passband.
Probably more to be fixed, but woking on one thing at a time should help minimize confusion.??
Several thousand uBITX transceivers have been assembled by others with no problems, so it unlikley that there is any problem with the instructions or the schematic.? As a licenced ham radio operator it is expected that you can read a schematic and folow the wiring diagram.??
Being in Brazil should not be a big problem.? Communication delay is minimal.? If we concentrate on one problem at a time we can fix one thing at a time, and then move on to the next problem.??
I will follow this thread and try to help, but others can jump in at any time.??
Arv. K7HKL _-_
I bought a cheap baofeng microphone thinking that the pinout for it was correct to accommodate the wiring on the radio.? Now I have no idea if that is the case or not.? I bought a 4 pin microphone and hooked it up to a stereo microphone plug but that doesn¡¯t work either.? I tried to the calibration, but the instructions in the youtube video are terrible.? Now the volume from the speaker, at 100%, is barely audible.? I wanted to go back and recalibrate, but I can¡¯t because the speaker volume is too low.? There is so much documentation on line but it is all confused between the various versions of the ubitx.? I cannot tell what the connection for the microphone should be.? It appears that from the ubitx40 to the ubitx v6 the pinout changed. ? The microphone I bought was an astatic 4 pin model D104M6b.? The pinout is below. 1 = shield 2=audio 3 =ptt 4=receive ? I connected it up as 2 tip of 3.5mm jack, 3 at center of jack and 1 as end of jack.? I left off the 4th connection.? I think the microphone works.? I still get no sound out.? When I push the button on CW I do get a tone and it broadcasts. ? I still think the unit does not transmit on voice.? I can receive signals now but again the volume is so incredibly low I cannot hear it with the speaker.? There is now an offset in the tuning frequency to the true frequency of about 4,000 Hz. ? I did a hard reset on the stupid thing by holding in the knob and turning it on.? That didn¡¯t help the volume problem.? It is still barely audible.? So it doesn¡¯t help with the calibration.? Now the menu says I should hear a tone of 10,000 kHz and adjust the signal to zero beat.? I really can¡¯t hear anything so I have no idea what to do. ? ? There are several on this group that might be interested in helping to get your uBITX V-6 work on SSB as well as CW.? Given the thousands of uBITX that are in regular use, it cannot be all that difficult.? Circuit design in the uBITX is not all that complex.? The voice part just amplifies the microphone and uses that voltage to unbalance one of the mixers to produce DSB, which is then filtered to change that to SSB. ? Does anyone want my ubitxv6?? I am done.
