Hello, i orderd my v6 complete pakkage last week. I payed by paypal but i didn't received any trackking code or anouncement that you received the mony and that you wil send it to my house in the Netherlands?????

TFT Raduino upgrade for V3 uBiTx ?
I have an early V3 that I have managed to kill the Si5351 so was wondering if it is possible to upgrade the raduino to the new V6 type. My eyes are not good enough to replace the si5351. I have sent an email to hfsignals about 2 weeks ago, but have not received a reply.
Failing that are there any other raduino replacements out there that are worth considering?

Re: V5 arrived in time for Christmas - wish I had known about v6
#v5
You have a excellent photo of the supplied microphone posted here. Out of the two terminals of the microphone if you observe one of it has 3 connections going to the aluminium body of? the microphone (In the photo the upper connection) That is the ground connection and without anything ( The bottom connection) is its live witch should goto the pull up resistorI suggest that if you have a shielded cable at hand then the outer beading should go the terminal going to?? the ground and the center conductor to the non connecting terminal. You can verify the grounding terminal of the microphone by continuity test by multi meter
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.
Excellent post, Arv!

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.

by this kit.
I do like it, but it is slow going. A few questions, which I am sure have been answered ad nauseum, but I cannot find the answers.
First, the microphone. I have what I think is the mic in the kit, but it has no leads.?
There it is, on the solder roll.?It has no leads! I do not know if, with my eyes and hands (they shake a little) if I can get leads on it. Anyone have any experience?
Next, must the mic be electret, or is the radio compatible with dynamic mics? Thinking a big old D-104 "Chicken Choker" (no not really), but no, I do have an old Radio Shack mic that went to one of their Ham rigs of the 1980's, which I think to be electret,
but not sure. It has the Icom/Kenwood/BaoFeng type plugs.
I look forward to getting it on the air, and as soon as I can, I am buying the V6 already assembled!
TIA for any and all input, and please be gentle with this "Old Timer" - the last kit I worked on had large "transistors" made of glass, and the connector strips were big enough to wrap a 14 ga wire around before soldering!

Thanks Bill,
I saw these before but I decided to buy one just now. ?I have some of the parts needed, I’ll just need to make an order for the rest.?

I bought this to test the AGC it works so its time to pass it on.
Basic (no case) V6 with AGC mod installed: 160$ shipped Con US
I will ship over seas but ask for shipping costs.

Re: uBitx Digi-Interface Module (Add-on Board)
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: Latest Build, Mods and results.
Can you send me a picture of the connections made to the KT1 KT2 and KT3 relays?? I have the board built and ready to connect.? I'm unclear about the connections.

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".?
