Sbitx v3 headless case
Does anyone have a design for a sbitx case without a display? I have no
need or want a display, I will use a monitor and keyboard. Or I'll use
headless with my ipad.
Post any pics or designs you

Re: uBitX fading receive sensitivity

K3 switches the LPFs out of the receive path, so it is unlikely that any of the LPF circuits are the issue.
As Scotty R. suggested, I would look for a possible heat issue.? This could be in any

Re: uBitX fading receive sensitivity

First of all is this happening on all frequencies or on particular band or
bands?
If on a particulat band or bands using the same TX LPF then the respective

Re: uBitX fading receive sensitivity

I had a similar experience, but the problem was not with the radio. It was a poor solder joint at the antenna.
Once I would transmit the problem would go away then start to fade until I would key the

Re: uBitX fading receive sensitivity

Last night I was thinking about it and I believe the first thing I'll try is cold spray. A bad solder joint could be the problem and cold spray sometimes reveals those.
Possible bad relay noted...

Re: uBitX fading receive sensitivity

the traditional way to clean relay contacts depends on being able to
carefully pry the plastic case off. Usually this can be accomplished.
May require small "jeweler' " screwdrivers.
Then take a

Hello,
I will not write too much more than previous colleagues - I also would start checking relays. Yes, relays. RX path goes through TWO relays K3 and K1 (type HFD27/012-S relay).

A dirty relay was my first thought, but the fading doesn't seem consistent with that. I'm just getting started with the problem.
