Re: W8TEE vft/tft questions
I think there is a library that accounts for this, but I don't remember which on it is. A little Google time on the Arduino programming Forum might pay dividends. Jack, W8TEE

Re: RF power chain mods and improvements..
Alison, You have put in some remarkable efforts in gain equalisation and I fully realise it is not a trivial task. Over years I have seen many application's struggle with this. 2 methods that come to

CW Transmit Frequency VS Sidetone setting #radiuno #ubitx #ubitxcw #firmware
Hi, I was recently puzzled about why my transmit frequency seemed to be about 1khz low on 80M. I was doing what seemed natural, using the CW key to key up the transmitter into a dummy load and check

Thanks for the help, Nick.? I think I will wait until Allison works out the flat power output problem.? 15 meters is my favorite band. 73, WA9PWR

Re: ND6T AGC implementation for uBIT-X
I believe Kees is kitting these up for 0805 parts. The 0805 parts are included with his kit. An 0805 is 0.08 inches long, 0.05 inches wide. Rational countries use metric numbers to identify surface

Re: toggle for low output and max output? #ubitx
On a somewhat related note, that code of post 44278 conforms with the stock uBitx firmware in that it keeps the BFO on the low side of the 12mhz crystal filter. This was done to avoid having audio

Re: toggle for low output and max output? #ubitx
There are 2 pole and 4 pole variants of that 45mhz crystal filter. HFSignals is probably using the 2 pole. If this method of transmitter attenuation is to be used,? would be best to keep using the

Re: W8TEE vft/tft questions
There are some encoders that do put out 4 pulses (two sets of A & B pulses) per detent. This has been discussed before. The fix was to make the code swallow two pulses and use the other 2 pulses. Arv

Re: Raduino issue
Hihi Sam, ha the universal cure...cheers then. In between two glasses of the beverage you could try to load the test software if you feel so inclined and see if the other Raduino inputs are working.

Re: Raduino issue
I did that. It seems like it's taking and reboots at completion. Top line flashes ubitx .20 and disappears. Bottom line says c 1.061 and stays.

Re: Raduino issue
Pull the board and remove the display, then try reloading the software. If you are on a Mac you might want to try a PC or Linux. For me the new iMac USB 3.0 ports did not connect and the older MB Pro

Re: W8TEE vft/tft questions
It appears that your encoder sends out 4 pulses on each detent. I'm not where I can test the code, but try something like this: void SetEncoderDirection() {??? int count = 0; ? ? encoderDirection
