Description

The RT22 model works, but I cannot program the RT22S.

The only difference I see is that the S has a channel display screen.

History

RT22S actually quite different from RT22.
RT22S has 22 channels instead of RT22's 16, plus has compander and scrambler options for each channel location.

I am curious on the RT22 model that works. At one point in time it worked now I get the dredded "The radio did not accept program mode after five tries.
Check you interface cable and power cycle your radio." Tried different ports, tried different (Windows 10) desktops, and iMAC. Awaiting on another cable to see if that works. Any replies helpful.

Kenny,
I am of the impression that this radio's hardware/firmware has been updated between RT22 production runs. I have noticed that the radio's casing was updated from the rounded style identical to the WLN and similar versions to a slightly more angular styling, so perhaps there were internal changes made at that time or at some other point in its lifecycle.
From reading various sources, including this site, the firmware change (affecting Chirp) might be as simple as having added an exclamation point to the radio ID string. It'd be good if someone could test that theory (or show that it's been tested). Unfortunately it might mean having two options to choose from (within Chirp) if you are programming an RT22 - "old" vs "new" versions.

Thank You Art - Right now we need these but are sending them back for a different model.
