Re: wrong frequency after software change.
#ubitx
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! Mike ZL1AXG On Sun, 11 Feb 2018 at 7:36 PM, at91r40008 <yvon@...> wrote: Did any one experienced this problem? |
wrong frequency after software change.
#ubitx
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, yvon NU6I -- 73, Yvon NU6I |

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? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?73 Mike KF6KXG |

I just measured a board. It's 4.9" x 4.7 x 1.1. You can shrink the 4.7 down to 4.5 with a different heat sink. It'll be a tight fit. Vince. On 02/10/2018 10:59 PM, VE7WQ wrote:

Hello,
I'm planning to re purpose my flaky Icom IC-25/AE (5"x5"x2") mobile rig, for the BITX40 with Raduino I ordered. I need to know, if it would fit in it's 2" deep box. Thanks. George, VE7WQ |
Re: Fast tuning buttons
Jack Purdum
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.

Hello all! I received my bitx40 last wednesday (total newcomer).
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! ? Thanks for the advice!? 73 de OA4CKN, at grid FH17lw. |

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. Raj At 11-02-2018, you wrote:
ok now that I slept for 12 hours doing better. ok square pad # 12v---pin #3 no volts---pin5 no volts---pin8--0 volts----pin#9--no volts---pin#12---12 volts---pin #14 12 volts---pin #16--12 volts. hop that is correct. with PCB & Radunio unplugged measured connunity, connunity ok. checked k3 no voltage on any pins on receive.
