you can have a wire patch from relay pin to the PTH hole after seeing the Photos from RAJ. All the best sarma vu3zmv

I suppose, it is closely following blinks of red LED in arduino board.

BTW, what is the version please? Sarma vu3zmv

Please check relavent sch ,Chris. I suppose rhe relY pin is expected to go to a coil's pin. Of so botht relatag and coil pon are on same side. Perhaps you can have a simple short jumper, right !

With ANT connected and volume at nominal level you maynot feel the encoder clicks, I suppose. Sarma vu3zmv

Many a time it happens , a person who feeds lot if people himself not haing a loaf to eat, lol. A paradox situation.

By re adjusting tx bias, one could use upto 20v for highwr Tx power( beware the need for improved heatsinking), the remaining circuitry can be made to work on 12v by a suitable regulator. One could us

Better replace k1 relay

Did you wire up the 4k7 resistor from Vcc ro cw wire?

#ubitx

Yes. I get you. Thanks. Perhaps the new method i saw on the same site, but as I went thro' hf signals ubitx site to day, this is what I found. Perhaps Farhan may have to relocate the relevant section

#calibration #ubitx

Evan, I saw the details. Ashar Farhan says to tune to a Shortwave AM station and adjust "calibrate for soc alled zero beat, and later select an SSB signal for loudness (not clairy.) Then fine tune usi

#calibration #ubitx

Ravi jee, Just use kd8cec , select the lcd type in ubitx.h, select ver5 on main file, just compile. Later pwer on Nd while calibrating change bfo to 1105550 and click ptt and save. Also power cycle. L

Richard, Wish you a happy and healthy Century. It is proudto see you assuring fiing thngs at your age. Of course i am at 74. Still sble to manage. Regards Sarma vu3zmv

Straight indication of dry contacts of the relays. In telecom we usedto feed a 2mA wetting current theo contacts of relays. However tou may very carefyll replace the two relays that areresponsible for

Perhaps hf signals can send a raduino cheaper. Try once , before landing on an 30$ item.

Press ptt or encoder as per the message. Later switch off and re switch on after a 5 sec gap.

Incidentally, do you use stock firmwsre or kd8cec phd lee firmware? If LEE's firmware, i fear that the result is not gettong save or factory default mY not be possible. One of these things is happenin

As far S v5 is concerned, the IF is 11.0592 MHz. Hence during te alignment,it is suggested to pre park the BFO at 11.055.5 powersave. Later manage to tune wwwf like known standard frequency and get th
