A spring or star washer should stop the screws from becoming loose

Hi Scott, I read your email thread and learned about the SWR/Pwr sensor installation process.? I am waiting for the parts to be delivered and working on other projects.? It is not a priority for me

Hi Nanak - I am having a very similar problem with the sBitx_v2. I can see some noise in the waterfall display if I raise the rf gain but no stations at all. Even very strong ones. The noise level

Hi Evan, I think you may be referring to my experience in adding the 60dnm.com 100W SWR bridge to my V1.? I would say 90% of my issues were self induced.? If you were to add the sensor to your V1

thanks!

Possibly different thermal expansion rates between the two metals and heat cycling in use or in transit is enough to take out the swaging or press-fit. I think I would consider a tiny drop of a

I agree, we need a program that will generate an adif file. Even better if it were generated automatically by the Sbitx software. -- Bob AA4FJ

Screws may loosen due to shipping. Although I have only experienced this with the FETs' fasteners. As a precaution, I also wrote and added longer fixing screws so that the screw is not only held by

But Gyula is definitely right that his loosen screws and nut procedure is a must specially for early s/n units. -P #5

Farhan, thanks for info. I know it but if remember well there was reported finals blown even after update and txcal. There are no more reports from users about reliability of finals after correct

Thanks

Evan, There is code to clamp the output down if the power levels get out of hand. It is in sbitx.c, read_power(). - f

This is a reboot of the original monoband bitx20 that I am presenting at FDIM today. - f

We are checking not just the screws but also extended keydown on each radio. See our test processes documented on sbitx.net. I suspect that the threads are failing an loosening up the inserts

Bob, 1.Is the 22 watts the reading on the sbitx meter or is it on an external power meter? If the sbitx meter is showing low, then you have to run the metercal once again. 2. As a part of our testing

I think they skipped checking the screws. If so, the FETs may not have been able to transfer the generated heat to the heatsink. -- Gyula HA3HZ

Many have requested an sd card image as an alternative to upgrading the sbitx software. Upgrading the software is the recommended way to go as it preserves the personal settings, logbook etc. Using a

Petr, Just the software update will not prevent a blow out, unless the txcal routine has been run on it after the update. I have detailed these in the write up on sbitx.net dated May 11th, 2023. - f
