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

Wow that looks sooooo good. Great work Cheers Kevin VK2KTG

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

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.

Did you watch the video? rOn

absolutely Jim

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

Yeah but the point is it’s the receiver that should offset. Not the transmitter

Gotta offset, can't hear em on the carrier

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

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

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

Nice setup !! Gordon

I have ordered but not yet received a uBitX which I plan to use for 40 meters WSPR.? I have two questions: 1.? Is the simple crystal for the Si5351 sufficiently stable (at least after warm up) for

No sooner did I say that some folks will be challenged to correct the spur issues with surgery and internal boards… and low and behold !… KE4MIQ posts a very simple outboard filter board…

That’s why I mentioned it. And yes, most radios do have bandpass filters at intermediate stages for the very reason we are seeing a problem in the uBITx. Sent: Sunday, September 2, 2018 4:46 PM To:

MRModder it is not so much a a mess. If they realise they cannot safely add an amp and they spin the dice as far as a letter from the FCC/SMA then the sun rises each morning much the same.? The

I have a 3.5 and am patiently waiting on Alan Merrill to update the 3.5 lcd. You can load the released Hmi/tft but will only fill out 3/4 of the larger lcds

It has been released. Not sure lcd size you have as he only supports the small size. Lcd.
