Great idea Jim as the Teensy 4 opens up so much opportunities. A great rejuvenation project for my V3 board, now sitting idle (a V5 board took it's place in the rig). Awaiting your international shipp

Hello Martin, Welcome to the world of conditional compile. Here are the lines in the ubitx.h file that you need for the stock standard V5 board (you can copy/paste to replace existing lines 25 to 35 w

No problems Razvan, glad the information may be useful. Ask if you need any clarifications. 73, John

Hello Razvan, I had the same objective of creating a portable rig. The easiest and cheapest option I found was to add a second Arduino (a Mini in my case but can be a Nano, the sketch is the same). Th

Hi Rob, No problems. Ok for the regulator, that should work just fine. Regarding the place to insert the Teensy, here are my thoughts: If you have an AGC then before the volume control as you mentione

Hello Rob, In my experience ground loops on transceiver to CPU based units are only an issue in TX when using "longer" wires. For reference I used a second Arduino Nano mounted inside the uBitx and al

#ubitx #teensy #filters

Hello Chris, Do you mean both crystals on the Raduino proper and on the Nano's board? For comparison I do have birdies (mine is a V3) here and there as I have on my FT-817, albeit not as significant a

Hi Jeff, Glad you resolved the issue. My V3 uBitx is as sensitive as my FT817 with the preamp off. Could this be a perceived effect of the relative lower audio chain gain of the V4 units, or is it tha

Hello Tom, Further read of the manual reveals that as you said the 256 registers are at one I2C address, and are divided between control registers and EEPROM addresses (two banks of 128 bytes). The cu

Hello Joe, Some of us did have that issue and here the link to one solution: https://groups.io/g/BITX20/message/57047 You can go back up to the thread level from the post, but be aware I made a mistak

Interesting devices. The boards also have 2 or 3 general I/O pins (depending on the usage of the LED), and 128 (256?) Bytes of EEPROM. From a quick read of the Arduino library (https://github.com/Fatt

Hi Jeff, Here is the link to the thread. https://groups.io/g/BITX20/topic/8872690#54576 In summary it was the nano's crystal frequency. I changed the nano and it solved the issue. To see if it's relat

Hi Brad, Thanks for the information. I should be able to give It a go in a week or so and I'll report on the results. Even at the high rate of compression/limiting where mine is at present I get repor

Hello Brad, Your tests results and analysis explain the results I observed with my SSM2167 module where I had no change when adjusting the noise gate (the Mic sound input was always on). I would prefe

Hello Adrien, Regarding the Mic preamp I would consider the SSM2167 based module rather than the MAX9814 as based on my usage of both the MAX is more of an ALC type rather than compressor type as is t

Hi Jeff, Not sure which version board you have, but could it be usb/lsb related (despite the 160m absence which I presume was in LSB)? If it is, I would look at the Arduino clock issue which I suspect

Hello Ted, Have you looked at JS8CALL? It works on minimal HW like a PI, reports positions to APRS, allows precise locations with a variable length maiden locator format, uses the FT8 modulation for v

Bob, The most effective squelch I know of for this purpose is a syllabic squelch which detects human voice and ignores static crashes and tones. They are built for example in the CODAN radios and in m

Hello Mike, In CEC firmware the CW BFO can be set differently to the SSB BFO. See the menu item "Set CW RX BFO" in the rig's settings. It may be way off. Cheers, John (VK2ETA)
