Thank you for your response. I do not have a second receiver?to check it with. The relays do click when the PTT is pushed. -William

Thanks much Vic, That makes sense....I saw it went to 10mhz and that the receiver went dead, now I know why....Should be able to get it on the money now....Mike

Hello Peter, I would appreciate some pictures please. I am interested. Thankyou 73 Ian M0IDR Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows

After serious deliberation, I have decided to sell my ubitx transceiver. I have done Raj's mods - the 45 Mhz filter inductors replaced by smd's, the new filter in front of the second mixer and the 2

I am afraid it is correct, although bothering. On 'USB bands' is the other way around, it shows 700hz above. So be careful especially during contests not to transmit outside the ham bands otherwise

Hi Sascha, Sorry to hear about the dead Teensies...ouch. Fascinating problem. After reading you email a few times and to make sure I didn't jump to conclusions: 1. your "spy" connection towards the

Mark, The 0.1 uF capacitor goes on the tuning pot between wiper and GND. you can add a 100 pF capacitor in parallel with L7 to reduce the second harmonic. -- Ion VA3NOI

Thanks I am replacing the v4 today with my v5 and will start with the cw test into the dummy load on all bands. My v4 on cw 20m band still has the issue with spurs which may be the relays I have not

You will have to remove R60 then you don't need another blocking cap. If you don't remove R60 then you need another cap. Raj

Jim and all, I found this board as it came from hfsignals not passing my tests. Even at lowered power out. Howerver when I reduced the drive by RV1 and increased the modulation level (mic) the Po

I know the calibration method changed from what is posted on the HFSignals website for the v.4 boards, so perhaps the new method applies to the v.5 boards. In the version 4 when you select calibration

I should have mentioned, do not put anything in the "CW Freq Adjust Value" box. That will add to the offset you have already selected when you set the CW Side Tone elsewhere. =Vic=

This bothered me as well, as the TX is offset by the amount that you have set your CW tone for. I think it might have been better to offset the receive in CW mode, and Dr. Lee has provided that option

There is a dc blocking cap in the ubitx circut, c60, you don't need another. I used a pair of audio transformers to isolate the radio signals, one on the mic side and one on the input side to the

In Linux, cwdaemon and XLOG.

Thanks k5ess Frequency rolloff can be calculated using standard formulas for an RC network. Good practice for the radio amateur. Depends on the resistance of the input circuit you were driving

FWIW here's my version of the Easy Digi.? I use it with a USB sound card dongle and a serial port for TX control. Mike K5ESS

So I swapped out my lm386 thinking that I might have blown it. Now I get ALL the am frequencies. Any ideas on what to fix next? ?Video included.

I am still fighting to get this working. While installing the first level converter I somehow managed to burn the Teensy controller- so I had to wait for the new one. In fact this project uses the

Dr. Ian Lee, Your firmware for the 7" Nextion displays is missing MANY of the configuration options available in the other display sizes. Please see photos for example. Forgive me if I am making a
