Re: wrong frequency after software change. #ubitx

Mike Woods
 

Sounds like the settings in EEPROM are scrambled.  Have you used uBITx Manager to check?  If they are scrambled you can use uBITx manager to fix them too!

Did any one experienced this problem?
After uploading the software from Ian Lee I was really happy how it behaved but that didn't last.
I uploaded another version (unfortunately I don't remember which one) I couldn't hear anything
except background noise and in transmit my SWR was over 8:1. I checked all my coax and
switches but still the same. So I connected another radio at my desk and it worked fine.
Finally I connected my scope and found out that the output frequency was way off.
On 7058 the output frequency is 4032
On 10101 the output frequency is 5770
On 21000 the output frequency is 12000
On 28000 the output frequency is 16050.

The frequencies are approximate as hey were measured with the scope (a TDS2024B).

Loading any other version of the software, even the original one, doesn't restore the rig
to the correct frequency. I know, I should have noted which firmware I was using but I
didn't.

Any suggestions or clues?

Thanks and 73,

Re: Box size #bitx40help

Thank you again. 


My main concern was the height. 1.1 inch will clear the top for sure.

Maybe I can use it's mike, built in speaker and optical encoder tuning too.

After doing some tests with the rig, I made the mistake of transmitting near the Bitx40 with an ICOM 725 with a badly isolated tuner,

A quick flash, smoke, and the bitx40 that was only on, no antenna connected, died. No more tranmission or power output.

What components should I start checking or replacing?

Saw the pic of the IC25 at your link. A cool project would be to utilize the rest of the stuff on the front panel for your B40.

Tinny sounding electric miss on uBitx

Mike Lichtman
 

I was trying various electret mics with my uBitx today. Most of them sound very tinny lacking midrange and bass. 
This raises several questions: 1. is it me or do others find the transmitted sound is tinny when monitoring in another rcvr?
                                                 2. Short of an equalizer on the mic input what can be done? A cap, if so what value  .05 ? and where?

Fast Tune works by observing the rate at which the user is turning the encoder. The timing and tuning rates are set with #define starting around line 64 of the attached files. For me, if the encoding is pulsing faster than once per 100ms, I'm doing a Fast Tune. Slower than that and I'm just tuning around. Read the code in loop() to figure out how to use it. You will need to put both files in your project subdirectory.

Sounds like they have it in stock.


Do you know how deep a box I need for the BITX40 with Raduino?


I'm planning to repurpose my flaky IC-25/AE (5"x5"x2") for it.

Thanks Jerry! I had the issue of the broadcast station at los volume setting but after soldering a 10nF capacitor between cursor and ground of the volume potentiometer, the station dissapeared! 😁

Re: uBITX woes, feeling disheartened. #ubitx

 

Sorry all the voltages you mention are wrong!

Pin 5 & 8 MUST have 12v if your board is connected to power supply 12v. No 12v means RX will not work..

Pin no 1 (Square pad) can have 12v ONLY on TX.

I suspect that you are not measuring properly or counting the pins wrong... cant be this way off.
