Re: #radiuno External VFO? #radiuno
Yes you could but make sure you get the levels going to the TT right. There are other arduino based VFOs that could do the same work. Either way your rewriting the code as the raduino does things that

Re: RF power chain mods and improvements..
Above 22.5 MHz, a HPF cuts in with a threshold just below 22.5MHz, again killing off all the unwanted mixer products.<<< Sounds plausable but then try a typical 7 pole HPF or LPF and see what it looks

Re: UBITX. FT8 heat sink requirements #ft8 #ubitx
Barry, just out of curiosity, what current and voltage do you run when doing WSPR? I sit at around 36 volts at 1.4 amps, and the heatsink I use gets a bit too warm to touch unless I run the fan which

Re: RF power chain mods and improvements..
No.? The filter in use for 18mhz is the one used for 14mhz and has a lower cutoff around 20-21mhz and the firmware selects the 35mhz cutoff filter for 21mhz or higher. They have no impact on low

Re: UBITX. FT8 heat sink requirements #ft8 #ubitx
FT8 does not have a heavy duty cycle. The other modes DO. I have a small 5v fan with a dropping resistor to quieten it, and the long duty cycle WSPR works fine.

uBITX case and heatsink
I found an old BUD box about 10x6x3 1/2 inches. The uBITX fit in just fine when I cut a hole for the display and out the back for the heat sinks. I later found a large heat sink so fastened it to the

Re: #radiuno External VFO? #radiuno
That makes me think of the Purdum/Zia DDS VFO I just finished making work in the 40m rig I built from their kit/instructions. I pretty much rebuilt my dining room into a workshop just so I'd have a

Thanks, Allison. I'm actually going to stay out of trouble for the moment and wait until these mods are "final"-ized (pardon the pun. You know far more what you are doing than I can understand -

Re: Can't get my uBitX to transmit CW on the Dial frequency
Ok, so this issue is of great interest to me. So far, CW is the only mode I've been working...and unsuccessfully at that. My uBITX is still using the factory installed firmware - I haven't changed
