programming cable for the EF Johnson 5100 ES portables

Charlie Porter All Messages By This Member #58 Hello All, Looking for a programming cable for the EF Johnson 5100 ES portables. RFGuys seems to be out of business even though their website is still running. BlueMax 49ers "temporally" out of stock. Can't find any on eBay. Anyone have a schematic? Any other sources? -- Charlie - N6JOA
Pete D All Messages By This Member #59 Charlie, I see the service manual is out on repeater builder web site. A quick look shows the RS-232 chip is built into the radio, so it shows that it's a straight through cable from the RS232 to the radio.? The hard part might be finding the connector on the radio side. Hope this helps. 73, Pete N2MCI toggle quoted message Show quoted text On Sat, May 21, 2022, 8:23 PM Charlie Porter <caribou42w@...> wrote: Hello All, Looking for a programming cable for the EF Johnson 5100 ES portables.

Charlie Porter All Messages By This Member #60 Hello Pete, I hope that you are well. Thank you for this reference, Yes, it will be finding the connector on the radio side. I looked at some of the mics available on ebay to see if it might work to use the connector on them, however they are missing some of the needed pins to make that cable. Thank you again - very much appreciated.
