I just got on at 7:00 Central. Lots of noise - maybe Christmas Lights. ?Not hearing anyone but will hang out for a while.

Called CQ until about 7:20. Heard one very weak signal about 7:10, but not strong enough to copy anything.?

Only worked N6ORS Keith in WI 4x4 and 5x5 so far at 2045Z. Can hear NX2U calling CQ but he isn't hearing anybody answering. Still listening to 277 unless i hear otherwise.

Re: ubitx circuit, wiring, source code on github
Just for giggles, I downloaded the recent 1.8.5 release and downloaded the github source. After selecting the "ubitx_20.ino" sketch, all the rest of the sketches loaded up in the IDE.

Hello Jack,
It would be great if the first comments were a list that indicates which version of the compiler and libraries were used. This along with where each may be obtained would make life

Re: W8TEE B40 real time clock connections

Thanks for that Michael, do you know if the QRP Labs DDS is AD8950 - or are they using the Si5351? According to some, the issue is with the AD8950 and its handling of data on the bus. I'll take a

Re: ubitx is available for $109, there are a3 catches
Hi Jerry,
I do not agree with you in that I had an experience with an FT290R whose
polarity was reversed.
The diode, a high current one installed by Yaesu shorted and a 20A PSU fuse
blown.
It has to

Re: ubitx is available for $109, there are a3 catches
Hi Gordon,
The reverse polarity relay is very simple and works fine.
Basically the supply to you equipment goes to the normally closed contact.
You put a diode in series with the relay coil in

Rob,
?Take a look at the QRP Labs QLG1 kit.? They use it in their DDS VFO kit to maintain accuracy in frequency.? But they also use it in their Clock kit to get date/time information from GPS

Re: ubitx is available for $109, there are a3 catches
Yeah BIG warning on this scheme. Elecraft uses this in the K3… for the “ON” switch by controlling the gate. I had mine SHORT in the CLOSED/ON position. Doesn’t do much good when the diode

Lucky for those of us that do not have access above 7.200, 7.277 is wiped
out by a broadcast station.
Back to 7.177, just monitoring as the rest here have had an early night.
