One comment of interest to me was that the plug in display board may have issues with it not being fully plugged in. Maybe this can be verified, also. Simple problems often expand to fill unexpected concerns.

I had my eye on on the G90 and 5105 sold by MFJ since I had the XM1 and the predecessor to the G90 before. (My son has it now, he's a ham in Sacramento and loves to take it to the mountains, first contact was Japan)... The cost of the full V6 kit still saves you a bunch of money and can still supply bragging rights for putting it together.

When operating QRP, the rig is half of it and the other half is the antenna. Maybe more than half... For portable, I plan to use an endfed dipole with 9:1 unun since it's easy to put up and covers all bands. But that's another story.

Re: #v6 For sale, #v6

Bob Lunsford
 

Thanks, Dean. I feel much better now. {;->

I plan to use it mainly for mobile purposes. The home rig is an FT-890 and it also has no menus buried in other menus. I had an FT-450 previously and let it go because it was not that good on AM Broadcast — after getting the menus set up, I rarely went into them so that was not a complaint.

I had the V4 before and it was OK but sold it because it was marginal to not being accepted with FCC standards on 20M and up, even though I seldom went above 20M, mainly using 17M when the band was open. Seeing that the V6 passed all FCC standards was the clincher for buying it and the full kit with cabinet is nice to show off, too. I look forward to getting it later this week.

Thanks again, Dean.

Re: Bitx case design issues #ubitxv6 #parts #v6

Bob Lunsford
 

Doesn't putting a nut under the screw's head make it stick out from the cabinite? Wouldn't this cause even more interference with the back of the volume control knob? This might be a ramification of doing it this way.

When you use the Champ crimper's screw cutting feature, you screw the screw into the tool from the threaded side and the unwanted part is cut off and then the screw is backed out the threaded side. This cleans up the screw's thread. And I've never had a problem screwing a screw with part of it cut off. The threaded part it's screwed into takes care of it; it had a shaped area that accepts the shortened screw with no problem.

Those Champ crimpers were available at Sears and other "fine" stores but like I said, I get them at flea markets and they cost me somewhere between one and two dollars. I got one Saturday afternoon for one dollar from a guy who was cleaning out his garage. Now I have about four of them.

There are probably as many ways to shorten those screws as there are

one minute at most. Finer file then beveled the ragged edge. Removing
the nut cleaned up the ends of the threads on the way out. That beveled

Re: v6 with a 7" Nexion nx80 #ubitxv6 #nextion

There are some Nextion 7" screen software in the files section. Not sure if anybody has actually tried them out. Look under AJ6CU. But there may be others. Since the 7 is the same resolution as the 5", if 5" works on. v6, then the 7" should work too. (with the right firmware, the Nextion firmware is specific to the screen and enhanced/basic gpu),

Re: Volume Control Knob

I used a harbor freight belt sander and a grinding wheel to file the volume button down and consequently allow the set screw a much more secure position on the volume shaft.
It fits and works well now.

For those who are not able to easily find a knob for the volume control, her is a quick and dirty — and cheap — way to make do until one is found...

Use a screw on wire nut. I used a yellow one on a previous V4 that I had and have used this "quick fix" for knobs on other radios. Since the volume control is a type of nylon, screwing on on is ease but I suggest holding the shaft with needle nose pliars to avoid putting too much force on the internal mechanics of the volume control when putting on the wire nut. Also, a little care must be used when screwing it on to make sure the wire nut is lined up properly and not skewed.

Just an idea...

Re: BitX40 Dial Locked

Allard PE1NWL
 

Guy,
if it isn't really in transmit then perhaps there's something wrong with the PTTsense circuit.

see https://github.com/amunters/bitx40-raduino-v2/blob/master/PTT%20SENSE%20wiring.png

The PTTsense line is connected to pin A0 of the Arduino. Measure the voltage on A0 with a DVM.
In RX it should be LOW, it should only go HIGH  (+5V) when PTT is activated. 
If it is HIGH all the time (even when PTT is not activated), then perhaps the input pin A0 is blown.

What voltage do you have at A0 when PTT is activated (TX) and when it's NOT activated (RX)?

Anyone try this screen yet?  before you ask I bought this screen a while ago original for the bitx40 v4 had some issues on the upgrade to take the screen and eventually had a meltdown  with the board.  

So I have the screen ideas for anyone who has hacked around with this screen.  Otherwise I'll start at Nextion as a starter.

Maybe a moot point if I don't get my transmit issue resolved.


Re: ubitxv6 mic not working fine #ubitxv6

Okay I isolated out all the microphone components by removing the cable.  The issue still occurs as I plug in the plug to the radio with the wiring plugged into nothing ( I suppose there cold be a short in the pinched cable inside the plug.  But I also plugged a computer headset with isolated microphone TPS plug and it did the same thing.

  

The cable connects to the TRS jack with the following:

 

White on the microphone is connected to Sleeve at the plug

Green in on ground on microphone but not connected in plug

Red is on microphone in microphone and Tip in plug

Black is on PTT and ring in plug

 

Both Red and Black wires are mechanically crimped in the plug it’s possible the wire shielding was exposed I suppose.


I pulled the board completely out and looked at the solder looked fine.  I tried it out of the case with the plug in and it still did the same thing.  The plug itself seems like it's mechanically working fine.

Any other ideas?

Re: V6 Alignment

Evan Hand
 

I am not familiar with the TSW v6 Teensy upgrade, so I cannot be sure the steps listed are correct.  The main point is that it will not work with the stock v6 firmware.  You would need to upgrade to the TSW Teensy upgrade from the stock Nano. Fahran's video will work with WWV at 10 MHz.  The tricky part is the confusion that the added tones and clock ticks create.  It might take longer, however there are brief periods where the side tones are suppressed, and you can zero beat easier.

There are other benefits of the Teensy upgrade, especially if you plan to do mods to the program.  There is no room or processor speed left in the stock Nano.  

Above is my understanding of things that I do not have first-hand experience with.  Use accordingly
