Re: TX Debug Steps?
Buy a few pieces of cheap test equipment. A dummy load. Cheapo watt meter/vswr meter and RF probe. If you can¡¯t afford this get someone to fix it for you, before you do need a new board, Alight bulb

Absolutely right about using a new plan and your¡¯s and other¡¯s suggestions! Have to think through the new heat sink . . Maybe leave wspr to qrp labs qcx for now; purposely built for that. I have a

Re: VOM Advice? Simpson 260
The simpson requires a 30 volt battery that is generally not available, expensive when found. I have 10 3 volt cells in mine, so consider that expense. The voltage and current work fine without it but

Re: VOM Advice? Simpson 260
A great multimeter designed by Simpson in 1960s. I had a chance to buy two of them for telecom training center's needs in India.

Re: How hot is too hot? #ubitx
I would prefer to use unregulated 12 or 13.5V for back lit by cutting it from 5V regulated and manage to change the series resistor to maintain needed current. Regards MVS Sarma

Re: TX Debug Steps?
If it is putting out and you are not getting contacts, you may be over driving the audio going from the computer to the ubitx.. You may not be set up correctly in the software. Make sure your computer

If you are using WSJT-X for WSPR there is a tx% setting.? At 100% it sends every time cycle, lower less.? I still wouldn't tx WSPR without a plan to remove the heat but a lower tx% will also give

Typo: you have to solder a 4.7K without the resistor it will start keying the transmitter as you described.

Re: uBitx start problem #ubitx-help
I used a Sunil case with a separate board where all the jacks and the 4.7k resistor are. So I will apply your advice. Thank you again for this valuable info. 73 QRO from Gilles F1BFU 2018-06-16 13:09
