If using the mic input to do tune-up keying, keep in mind that is is not necessary to go full volume. 20-30% of full volume should be enough to at least give enough RF out to do an initial and probabl

okayJohn, i had the same problems. Mic wasn't working, and the freq was out totaly wrong. Get many tips from guys who are a lot better with elektronics then me. But, after calibrate serveral times....

Yes. Could be anywhere in the antenna system with a DC path to the rig.

Thomas, I am not sure that the impact would have translated to the circuit board if it was in the case with the top on. The board is mounted on the bottom of the case. It could have (maybe) caused an

Hi George, I would suggest looking at the S-meter while removing power to the PAM8610 amplifier module. I've also been playing with using a Class D audio amplifier in my V.4 uBitX, but so far I've not

Lou It's good to know that it is being used. As I indicated, my main concern is that some areas are not 100% accurate and up-to-date. M

thanks

They are to add another filter optimized for CW. The idea that I have seen was to use another crystal filter with a different frequency and narrow passband. You would then change the BFO to put the si

Litle measuring on a selfmade dummyload, 10mtr 18.4 volt, 15 mtr 22.0 volt, 17mtr 23 volt, 20mtr 23 volt, 30mtr 29volt, 40mtr 32volt, 80mtr 32.4 volt..... So is good i think... Regards Rene Netherland

Thank you Vic! I did not know that was there. I will need to give it a try. 73 Evan AC9TU

I might try to use the existing Keyer plug to see if this would work, but the RigPi is not CAT control setup for uBitX so can't CAT connect naticely to RigPi will try and emulate the Yaesu 817 CAT con

Hi Reed, Thanks for your answer. I will definitely evaluate that. Have a nice day.

Unlikely that it was static damage. The is a DC path from Antenna to Ground via L1/2/3/4 and T2. Raj

Hi Dave, I tapped that relay with the scriwdriver handle, but nothing happens. RX low sensitivity is real, I could hear strong signals on 40m at evening, but I have to keep the vol. control near its m

#v3 #ubitx #ubitx-help

I have seen the K3 relay, the single relay on the left side fail. While you are transmitting, tap that relay with a screwdriver handle. Measure the output and see if it pops up. If it does then replac

Oop, I missed how you connected the two radios to eachother and transmitted between them -- ouch! Remember, the receiver section is made to amplify microvolt level signals from the antenna, but the tr

They can be. The BFO is used for both receive and transmit signals. If the BFO is used to generate the sideband signal with the filter to remove the opposite sideband. If the BFO frequency is too clos
