Tonight I was setting up a Raspberry Pi2 with a simplex CDM750 and
converted usb fob getting all kinds of screwy problems. The Fob was
going in and out and failing. <br>
<br>
In my case, I was using a Astron SS-25 switching power supply to
power the radio and one of the 12 to 5 volt switching modules to
power the Pi. The radio was going crazy, the fob was going crazy,
the Pi was going crazy and the supply crow-barred. I grabbed another
supply, A Samlex SEC1223 switching supply and got the same issues.
We were having a similar issue with another node on Maui only he was
using a DMK-URI and a switching supply Powering a 12 to 5 volt
module and a simplex radio from the same supply. <br>
<br>
Turns out the guy on Maui solved the problem with a different power
supply for the Pi not hooked to the switching supply running his
radio. I'll be trying again tomorrow with a linear supply. I never
had a problem with a linear supply or a nice big battery bank. <br>

Well, how are you running them on a 12v battery or 13.8 power
supply with battery back up? <br>
Are they at home or at repeater site?<br>

Hi Eric,<br>
<br>
Interesting that you're having failures. I'd
like to hear more about the <br>
failed systems?<br>
<br>
I've been running -many- (more than a dozen
at this point) supplies of<br>
this style, on many projects, with no
failures.<br>

I have been using these on our system since
Doug put the RP2 build out and have not had
any problems with the over 1 dozen units out
there. Love them and the price. <br>
