[Premium-Rx] 3030 keypads

Mon Jun 30 13:36:20 EDT 2003

The 3512 does not bounce same with the R2307. I suspect it is a software
sample issue
if I had to guess. I hope to get over to a friend's house and copy the Cubic
software.
He will be able to produce proms after that. I am using VER 4.7A in the
R2307 which
is a mil 3030. I have no BFO function so need to sort that out yet.
Summer not radio season for me and quite busy. Send me the part number of
the switches and I will see if I have any. I have run into some push button
switches that are PC mounted.
I don't know what they should look like.    fc

Hi Frank et al,

As far as I can determine, all the keypad switch assy's are the same...it's
the overlay and firmware that varies by model & options.  I know you have a
few other models...I can't speak for them, but do any of the keys on 3512,
etc bounce?

I still find it highly suspect that all 3030A's so far have baggy overlays
and bouncy switches....all 3030's have firm overlays and no bounce.  Before
everyone runs out and buys new switches, let's figure out if all the 3030A's
have bad keypads or if they're simply not debounced.  As a start, I will
pour through my manuals .. failing an answer there, I'll check panel
interfaces between 3030A and 3030, including PC board # and rev.  If
everything there is the same, I'll swap a known-good keypad, which is a ton
of work, and see if that makes a difference.
