To do what? Your board was awesome, it has what I needed on it including the RF gain. I could just go the easy digi route but that kit you made was the coolest. You should consider running more.

Re: bitx v6 is here

Looks like I'm going to have to wait a bit longer to get a V6.  DHL claims they delivered on 12/26 (ordered 12/15), but no package to be found.  Neighbors don't have it.  I don't live in an area with "porch pirates" (or .  Security camera never shows a DHL van/truck even came to my house.  POD says it was signed for by "Delivered".  Message in to DHL for an explanation, but I'm not optimistic.   :-(

Re: V5 arrived in time for Christmas - wish I had known about v6 #v5

Hi Alex,  Good luck with the build, I have a version 3 and a version 3 with a nextion screen.Both are good but do need properly setting up.As to the mic it is electret,which is what the rig was designed to use.Dynamic won't work as the output is insufficient and won't match the mic circuit as designed.On the electret capsule,the terminal with the three connections going to the case is ground,the other is the audio feed.In conjunction with Arv's response hopefully you will achieve a result.Like yourself I am a tube ,(valve) man and I still enjoy constructing with tag strips,valve holders and components you can see.  Best 73 Ian M0IDR from the UK.

At 78 years old I share some of your concerns.  The earlier BITX and now the uBITX

units include working with smaller components, different components, and different

techniques than what we did in older times. 

 

(1)  Do a Google search for images of component names that you do not recognize.

That is the electret microphone that you ask about.  You will need to solder leads to the

two solder pads shown.  One of those solder pads is connected to the shell (use a

magnifying glass).  Brace your hands on the work surface to steady yourself and

maybe clamp the device to keep it from moving. 

 

(2)  Electret microphones contain an internal FET amplifier that needs power to function.

Checking the schematic for your uBITX you will see a resistor and capacitor that make

up the power-T for powering the electret mike.  Electret microphones normally put out

up to 45 millivolts of signal voltage.  Older crystal microphones might provide similar

outputs but a dynamic microphone probably will not.  If using a dynamic microphone

you will probably need a DC blocking capacitor to keep the electret voltage from

damaging your dynamic microphone.  Since the electret microphone pulls down on

the voltage supply resistor you may need to add a resistor across the microphone that

helps to center this voltage in order to preserve full waveform audio at the mike input.

 

(3)  Antenna matching is more critical with MOS-FET finals than it was with tubes.

Your antenna should be pre-tuned so that it provides close to a 50 ohm impedance at

your operating frequency (all your operating frequencies).

 

Hope some of this has been helpful.  Us old timers have to stick together if we are to

survive in the new electronics environment.

are you using a mobile phone?
is the mike of the phone near to the speaker?
you should see audio signals from the speaker as a green image.
then follow instructions.
if you have already set up the BFO, you can check how close you are to optimum.
I originally set mine up with a strong ssb contact to get best sounding audio.
checking with this utility showed mine to be set in the middle of the two vertical red lines.

The V6 is confirmed working with the AGC. Install is the same as other versions. The only change is just like the V4's you must tap the back of R70 as pictured,10ohm resistors are available upon request in the order comments for this tap.

Take your time to enjoy the build. V4 here about to get an integral audio filter.

V5 is plenty fine, and I don't mind using LCD.

Likely your radio shack mic will work. I am using an old kenwood speaker mic. Try that RS mic first. Some report low audio drive, but mine is fine.

That little mic was supplied for folk without radio stuff collected. Let's put it aside,  along with its tiny ptt switch.

I was running a skcc cw pileup with my ubitx last evening, yes I do occasionally call folk, even dx, on ssb with it.

Not sure what mic connector you have for ubitx? I cut end off my mic cord and installed 4 pin connector that came with my case.

Re: V5 Vs V6

Ken Hansen
 

I sold an unbuilt V5 kit to partially fund a complete with case V6 purchase.

As I understand, the V6 board is essentially the V5 board, but where you used to have solder pads, you now have all connectors attached, and only two items need to be plugged in, the encoder and the speaker.

The case is nice, the build is simple, but the economics of selling the unbuilt V5 board are a bit abusive. The current market price is $95, shipped. Shipping in US will be about $10-15, so you'll have $80 after sale, meaning you'll have to pay an additional $130 to get a complete V6 kit.

The V6 kit is a simple build, less than an hour by most reports, and aside from a few software oddities, a nice radio.

I have no regrets, very happy with my decision to get the V6 kit.
