If you have an old delta sx radio that you are using for 2 meter
operation (highband/wideband model) there is a new mod for these radios.
WA2VCS has written a new set of codes to allow the radios to permit
digital frequency readouts. yes frequency readouts!!! If you are
familiar with the SX models you know that they allow just a read out as
    Mode    Channel    Scan
       1             1             1
the new system is as follows
    Mode     Channel    Scan
      14            67           30   or    146.730
a big difference also allows frequency scans with display. Currently we
are running the beta 5.0 mode and have found no flaws in the coding ,
the rig works better than ever and it is as stable as it has always
been. Now for the bad news to do the upgrade you need to have a
highban/wideband Delta SX with an eprom of  19a704309 or equivalent,
have the radio currently working for 2 meters and the cost is minimal
the only part that is change is the processor the 80c31 needs to be
change to a 80c32-25 which is readily available from Pioneer Standard
for a cost of about $1.90. The only other thing that need to be
accomplished is you must remove the eprom and send it to us for
reburning with Bob's new code and there you have it reinstall the 28 pin
eprom and the new processor and the Delta become a formidable radio
again. For more info on this contact:
