Can you try the 2 tone mode and check the power output? Is it possible that there is a problem with the mic? The low level RF indicates that there is marginal output from the digital parts. I would

I Just upgraded the software to the latest on github. ?Then I Tried transmitting into a 10 watt dummy load and measuring power out on a qrp meter with various modes on 20m. With the drive set at 39 I

Hi Aaron, From what you are describing, I would guess that the Nano on the Raduino has stopped communicating with the display.? I would check the wiring to verify that nothing has come loose.? You

Dave, Ton and Toff do not apply in analog use.? Those are saturated switch numbers. Unlike bipolar MOSFETs do not exhibit FT (Frequency where gain goes to 1).. They sorta do but the mechanism is

Thank you...I was hoping that would be the answer!

My uBITX had been working just ok for it and I went to turn it on this morning and I'm stuck on 20 Meters. I'm using a 2.8" Nextion display. I try to use the band up and band down buttons and the do

Thanks for the invite guys. My sBitx v2 came on Wednesday, and superb at the moment. Just a problem with Morse decoding, it worked great at first, now I can't seem to see any at all??? [image: Error

When I look at the data sheet for the IRFZ24, the typical Ton/Toff delay times add up to about 40 nsec, which I think translates roughly to about 25 MHz.? That seems to me to be a bit marginal.? I

Works great now. Thanks. -- Bob AA4FJ

The IRFZ24 transistors are spares for the final output stage, just in case you damage them. Unless something goes wrong you won't need them. wrote:

I just received my sBitx-v2 ! There is a bag of parts, power cord, 3.5mm jack and two transistors...I think? They are listed in the parts list as IRFZ24N What are they for? Be nice I'm new.

Okay, I did it! It turned out great, about 30 watts at 100% drive for most bands except 12 and 10 meters are about 20 but that’s perfect for me. Thanks for these cool radios. Joel N6ALT

I don't know what the original connectors are or if these will be "more reliable" but the price is right and they are sold as sets : [

Hi Farhan, Okay I'll bite the bullet and give it a try. Thanks again. Joel N6ALT

Joel, The way to do that is to just edit the text file hw_settings.ini. You don't need to know programming. In this file, there is one section for each band and for each band, there is an entry called

I am no longer having this problem on my DE after Farhan's latest update, 6/14/23, now power output seems very stable. I would still prefer a easier way to calibrate the power output for the DE

The power connector has proven to be unreliable. Readily available 5.5mm x 2.5mm connectors have too large a center pin and although the power works, it is unreliable and intermittent if unless you

Hi all, After resolving my update woes (thanks Art N2AJO !!) I feel things are pretty stable. I know that the rig should be capable of upwards of 40 Watts on the lower bands. I'm not seeing that at
