Don glad it was operator error - it happens. appreciate all your posts here. I have a U3S for WSPR - its 200-300 mW reach VK, ZL, ZS and Antarctica on 30-40m. I need to build a few watt PA for 80 and

Ben, it can’t be that hard. Just disconnect the connector and see what happens. If the radio still go into transmit it is something else. Did you build in the board? Maybe a shortcut under the main bo

I finally found it. What threw me was that you have to turn on Setup mode, then dial PAST "Exit Menu" to find the select for the key type. Got it working! Thanks, Curt! 73, Gwen, NG3P

Like Jerry said, it’s definitely a frees-up of the arduino. I have the same issue when connecting the arduino to my computer (for cat control) and doing things to fast. Easiest way for you is to swap

No, I bought a ts-430s cheap because it was broken on transmit and it turned out the finals were shot - one of the finals transistors was a dead short - and a resistor got 13.8V 20A through it. It did

Ian - This is perfect and exactly what I was asking for. I traced the pin connections and looked at the schematic and came to the same conclusion. I am not confident enough in my electronic build skil

Yes it is a log pot. The human ear hear in a log fashion. Using a linear pot one will notice that, on a dvm you wll notice there is a change in voltage as you turn it up and down in a linear way. Now

The calibration function adjusts the base frequency of the Si5351, so all clocks are adjusted, including the PFO and 2nd IF frequency. For me I have found that adjusting the BFO, to get best response,

Excellent info, Roman. Thanks very much! I’ve been trying to work out a way to get a more accurate BFO adjustment and without having test gear I’ve been stumped. Your procedure does the trick! 73 Mike

With my handheld on 464.550, I get interference when I tune my uBITX between 7.185.350 and 7.187.350. If I tune my handheld to 464.650, then I pick up interference when I tune the ubitx to 7.199.550.

Bill, I've finally had a chance to get on my laptop. For the 20x4 display, these are the relevant files from the CEC v1.2 binaries. UBITXV5_CEC_Vxxxxx_20P.hex : 20x04 Parallel LCD UBITXV5_CEC_Vxxxxx_2

My firmware won't run both the two line display and the nextion display. When I plug in the two line display I don't see proper characters. What this suggests to me is that if you can see the 2 line d

Just to let you know I have managed to change the CW Tone using the encoder push switch method. I started the memory manager and uploaded from the uBitX. The CW setup table in the KD8CEC firmware now

I would ask questions like: What is the DC applied voltage during TX? It sounds low for CW even. For CW I'd expect near 10-12W however if you Power supply is below 12V what you are getting is then goo

I was able to use finally the NJM without issues; audio is really strong with the v2 model.

For the clicking, check the wiring on your key and mic inputs. Also, did you install the 4.7k pull up resistor? Did you make any adjustments on the biasing pots on the main board (the blue pots)?

Ah...good info. Thanks! I also added a BEC for some the 5v needs (plus a usb charge port), and a big dc-Dc buck converter for the 12v board. Now I can power it up with anything (almost) and the finals
