I had the same reports until I did the BFO adjustment. Mine is set at 11.996.100 for the best 73 Bill

Tim, please have a look on my folder (DK5LV) subfolder "LTSPICE XVII" in the BITX 20 group. I have made simulations of the AF preamp, the gain ist 46 dB.? I can confirm that the LTSPICE simulations

Hello Masa son, Thanks for sharing your info. Link for version CEC 1.02 please? 73 de Konstantinos, SV1ONW -- 73 de SV1ONW

Hi Eduardo --- where on the board do you see BURN MARKS? That would be the best clue. I have had both bitX40 and uBitx operating 25-50 feet from 2 WINLINK gateway stations for quite a while now

I tried USB Audio integration to ubitx. Inbon,cheap USB Audio(about $1) and Arduino to USB Passpower HUB. It's very good work for WSJT-X and CEC Firmware 1.02 ONLY USB 1 connector. USB MIc connects

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

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

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. Saturday, February 10, 2018,

First hand experience with fireworks! Sorry to hear.. RX working ?

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. Vince. -- Michigan VHF Corp. http://www.nobucks.net/

Thanks Vince! Great news. It would look nice. http://wq.uio.pw/wq/hamgears.html Saturday, February 10, 2018, 7:51:04 PM, you wrote: VV> I just measured a board. It's 4.9" x 4.7 x 1.1. You can

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

I answered in your other post, but here it is again: 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

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

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

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.
