Default Challenger Programming

Challengers don't take a PROM. The cables are available on Ebay and a search of the internet will turn up the software. BTW, the software is DOS...you will need a slow PC.

Default Oops!

I'm sorry...apparently I was thinking of the majority of the Challenger radios.

The 7154 was an "oddball" that wasn't even actually a Johnson radio, and it did, in fact, use an EPROM. If I recall, it was a low band radio (30-50 MHz). It was not a very popular radio due to the fact that you had to have a dedicated EPROM programmer for this one radio Many years ago, I worked for a Johnson dealer and even we didn't have a programmer for them!

Here is a link to the Yahoo radio programming group where you can find more information:

Sorry for the error.

Default Challenger 7154 Programming

Actually the Challenger 7154 is the same as a Shinwa SC-350X. It uses a 2404 (or 2402) EEPROM for programming.

There is S/W to program them, but I have never used it. I had a EEPROM reader and use it to change the frequencies, as the 2404 is in a socket. It's a 16 channel rig, with 50 watts. There are 3 versions of them:

A = 29.7 36MHz
B = 36 43MHz
C = 43 50MHz (useable on 6M)

As Kieth said, they are re-labeled Shinwa radios and they take a 2402 or 2404 EEprom.. The
programer can built with several "Off the Web" EEprom programmers.. Pony-Prg is the most popular one.

I've written a prg. to read the binary image file from the EEprom programmer.. My Prog., SHINSCXP, takes
takes that image file and creates a Ascii / Txt file that is comma delimited and can be edited with any
Txt Editor or spreadsheet program.. Process the ascii/txt file back in to the new Binary image file.. The
program only allows Ham Freq's..

Here's the link to SHINSCXP prg. : http://home.roadrunner.com/~n2mci/exe/SHINSCXP.EXE
