Re: CW OPERATION
Perfectly correct. On receive it is the BFO which must be offset and NOT the transmit frequency. When we had separate Tx and RX and the RX had a variable BFO (CR100/B28, CR300, Atalanta and their

Re: CW OPERATION
Thank Jerry, but in all of the software put out by the Triumviratw Skonk Works from our first public release for the original NANO and ever since, CW has not only worked properly but the Keyer has

Re: Sustained Transmit Power #firmware
I ran a WSPR beacon with my uBITX for several weeks. I found that it was rare for the TX frequency to drift during a transmit cycle. And only a HZ if it did. I ran a fan on the heatsinks and the

Re: CW OPERATION
This issue come up over and over. The factory software has (or at least originally had) the same issue. A comprise would be for the display to switch to the TX frequency when you key the transmitter

Re: VK4PP uBitx LPF BANK add-on Board
The ideas is to use exiting LPFs as is, with the option to add a fifth if you so chose, 160m... or better 10m.... But mainly better lay out and separate relays... I will provide a code snip-it for

Re: CW OPERATION
Ian's software is the most popular update available for the uBitx. He has added a lot of functionality to the rig and that is to be applauded. It's taken months of free time for him to bring it to

Re: VK4PP uBitx LPF BANK add-on Board
Ok, just adding a bit in here from my side: Relay 1-3 are triggered using the existing 3904s onboard. Relay 4 is a drived via a new 3904 and an extra digital I/O. Firmware changes will be needed

Re: CW OPERATION
I don't like to be overly critical, but I've been hinting for months now. I am now openly stating that KD8CEC's software has it wrong and it's been wrong from the beginning. I call on Ian Lee to clean

Re: VK4PP uBitx LPF BANK add-on Board
Kees - With 6 filters is the plan as follows? LPF1 = 80M LPF2 = 40M and 30M LPF3 = 20M and 17M LPF4 = 15M LPF5 = 12M LPF6 = 10M

Yes and it was reasonably well done but oversimplified a bit.

Re: CW OPERATION
You can do it the other way around, with the transmitter upset, but then you have to be absolutely certain that the user knows that their transmissions are offset from the dial number. That¡¯s not

Re: CW OPERATION
Yeah but the point is it¡¯s the receiver that should offset. Not the transmitter

Re: CW OPERATION
The explanation is absolutely correct. To all programmers of CW for the uBITX. You do NOT offset the transmitter by the sidetone frequency! When you press the key, the uBITX must transmit exactly on

Re: uBitx Unfiltered
So trying this from another path. Did some poking and looking at the Q90-Q97 path today ..Noticed that Q911 thru Q98 all have 100 ohms from the base of the transistor to ground (biasing network) The

CW OPERATION
Found this video explaining CW Zero-beating. So based on this explanation the following is illustrated for 7.040.000: Dial displays 07.040.000, you transmit on 07.040.000, and the receive is offset by
