No. It is keyed, and can only go in one way. I tried reseating it, etc.

uBITX v6 kit makes tones

KENT HUFFORD <kq4kkham@...>
 

Just got a UBITX v6 kit pulled together. (no soldering)

 

Lights up main screen fine. Can change bands and modes by touch screen. Cannot change freqs by knob,

 

However, when I rotate the volume control it just changes a loud audio tone freq out the speaker.

 

When I rotate the freq knob, it sends a loud audio tone out the speaker about 20-30 times a turn.

 

Punch the tune knob, nothing changes.

 

I’ve built version 3, 4 and 5.1 kits. They all worked ok.

 

Ideas?

 

Thanks in advance

When you finally finish testing the code and release it, it is already 20% debugged.

Have a good holiday but I suspect you will be barraged with this on the group owing to all those who just received or will receive their V6's in the next few days (or maybe weeks if they ordered via India Post).

Peeps,
There is a bug in the ubitx_ui.cpp in line 246. It should read "17", instead it reads "18" in the code as shipped. This makes the button for 17 meters (18 Mhz) unusable, you have to use fast tune or direct frequency entry to get to 18 MHz. I have patched the source code on https://github.com/afarhan/ubitxv6
Remember, that the v6 source code compiles only when saved inside the sketches folder of the Arduino. This is an Arduino idiosyncracies.

Ted, I have one question about the V5 board:

 

I have here on stock the metal 2N2222A and also the 22 Ohm SMD . When I understand well you modified the V5 board with  ONLY  22 Ohm on top of the existing emitter bias resistor…

I've read some (bit not all 250+) of the posts in this thread, and I'd like to put in a plug for the 2N5109 as a viable upgrade for the pre-driver and driver stages.  The price is right for reputable sources, not so different from the more oft-recommended 2N2222's considering one only needs one of the former for each pair of the latter.

I swapped out my 3904's in the power chain on a V3 board some weeks ago and on a V5 board more recently adding a 22-ohm on top of the emitter bias resistor (because they were handy).  Power gains were impressive:  40 meter phone went from aroud 12W to 20W and 20 meter phone went from around 7W to around 25W or better  This is with a voice compression board installed, though that board went in first. If I over-drive it a little on digital such as JS8, it peaks around 30 but I don't see any point in compressing digital at all.  With a fan on the finals, digital outputs of around 15-20 watts keep the finals warm but not melting and there is plenty of spring left underneath the compression threshold [i.e. not compressing at all yet].  Output is far more stout than with the 3904's and VR1 is set lower than it was without the upgrade.

I'd recommend this as an easy course of action even if one intends to run low power levels, as it evens out the power for 30 & 20 meters & up.

Reg. R10 you are right, but my idea was to make minimum changes to the original schematic, BF998 I goes from 2.5mA(0V Gate-2) to 16mA(5.5V G-2).
Summering all:
1. I picked up 12 all crystals from the board and modeled the filter on small one, result-very very close to original. I made Chebushev 1 dB 8 crystal filter 
and got 2.7 kHz wide near 2 shape factor 6/60dB;
2. Changed 45 MHz fitler to 4-pole DSF 753SDF  type D450 15GQ 15 kHz/3 dB very good one;
3. Befor the last TIA amp I put another 12 MHz filer(original).
4. Changed the output transformer to BN-43-202 x2 one and one wire in chain and 3 wires out in parallel to rise the power on high bands.

I've used JumboMail to send you the documentation for the JackAl and, as you will read, there are some parts you still need to buy (e.g., the display). The hardest part is making the two cables to replace the uBITX cables. It's not hard, just takes a little time. If you still want to build a JackAl and report about it to us, send me a mailing address and I'll send you a JackAl board. The understanding for this is that you will write to us to tell how it works for you. We'd also appreciate it if you didn't sell the board to anyone. In the meantime, you could order your parts.

We don't have a V6 yet, but since we replace the entire radino board anyway, I would think it should.  Let's put it this way, I will give someone a JackAl board if they agree to test it on a V6 board and write up a timely short report on it for distribution here. If you want to test it, please tell me the kind of building/test equipment you have. (Al and I are starting the PCB's for the projects in the book and it's going to keep us busy for a while.)

Version 6 Received, and working. Comments, questions, and a couple of bugs

Neil Goldstein
 

My 6 arrived yesterday here in Upstate NY. A great Christmas/Hanukkah present!

I have it up and running.  No QSOs yet, but some observations and questions:

1: When you go into the setup menu, your current Freq and USB settings do not appear, but it resets everything as soon as you try to enter the field. This freaked me out at first because the defaults are way off, and it left me with an unusable radio.  I was able to figure out how to get it back though.  WWV is your friend!  It would be great if the current values displayed first though.
2: 17M preset not working. All other bands work fine. 
3: Entering a frequency lower that 1000 kHz displays wrong. Example: entering 950 kHz displays as 9500, but is actually tuning 950. Turning the knob leaves you in the same band-range, but still displays as freq X 10 until you pass 1000 kHz, then it displays as 1000 kHz.
4: Screw on feet would be better. Adhesive not so great.
5: How do I display firmware version?  Not a huge issue right now, but going forward it might be helpful
6: Why so many extra screws?

That's all for now.  More as I play with it.  I have it hooked up to the Alex Loop here in the dining room, and will need to take it down for Dinner.  I'm home from work until Monday so I have time to play.
