Using Hotspots in close proximity to one another
Posted: Sun Feb 17, 2019 1:45 pm
I seem to be collecting Hotspots for some reason, you can never have too many I suppose!
There's a simple calculation: N + 1
N being the number of radios you already have plus another.
I have 3 ZUMspot hats in fairly close (6") proximity to one another, C4FM, D-Star & DMR, all on different
frequencies of course and about 4MHz apart. I'm wondering how susceptible they are to desense?
I've noted unexplained drop-outs from time to time, I don't suppose the RX 'front ends' are tuned that
much, or at all.
So I've cranked the 'RFLevel' down to 10 on them all and I'll see what happens. The original value is/was
100. I'm unsure how this value, and changing it, adjusts O/P power?
Anyone else experienced problems with close by devices?
