Spectra C9 head "Mode 0"

[KD4GPI]

I was trying to figure out why my Spectra T37KGA5JC9AK was not transmitting pl by checking/changing some of the codeplug programming. The radio was working other than that. I wrote the codeplug back to the radio and now the display only shows Mode 0. The HCN1073A control head was working fine just before this write. I had pressed the "Reset defaults" in several of the screens hoping that would cure the pl issue. I show the control head as "standard" in the F4>F2>F9 Radio Options screen. All the other programming is there. I can't access the control head line when I tab through the page. I am using RSS 4.00.01. Did I torch the control head in the codeplug? How can I get it back? My lab version is something like version 1.00.01 and it won't read the radio. I don't (hold the flames) have a saved old codeplug to write back to the radio. Any help would be appreciated.
Thanks,

If you have a C9 head, the Control Head Type needs to be set to S9000e

Is that something I can only get to in LAB? When I try to tab to that field it skips it like it is a viewable only option.

The information stored in the MLM, "codeplug", does not tell the
RSS that the S9000 head is there. So when you wrote the information back into your Spectra the RSS ignores the C9 head.

You will need later software to CORRECTLY update the MLM.Too easy to 'Brick' your Spectra.

So what does tell the RSS the S9000 head is there?

I see where LAB bit banging is the way to "turn on" features but it was working fine (minus the pl) before the write and I have never bit banged this radio. I tried another code plug that was saved from a D37 with a C7 head and I was able to access and change the control head from standard to enhanced to rotary. I tried the T37 again and it skips over this option.

Seems, from what you say, that another 'code plug' was writen over the original. This will mess up the MLM. Then when you read the radio the code plug information does not have a setting for the C9 head. The RSS does not 'look for' the C9 head and it does not read or write to the C9 head. Then when the radio gets reset by the RSS at the end of the write, the radio does not see the C9 head as it is looking for a A7 head which speaks a different langauge. The C9 head then defaults to display MODE 0.

If you do not have the correct tools to resolve the problem, I would be glad to 'fix' it here.

The way it reads it looks like I tried to write another code plug to the radio. This is not the case though. I just read a saved code plug in the Archives. Then I checked to see how the Control Head field acted when I tabbed to it. It allowed me to scroll through Enhanced/Rotary/Standard for that field. It was a D37-C7 that I was testing. I never tried to write that to the C9. I did a read, then modify, then write back to the C9. I never modified the head type though. Do I need to bit bang it back to S9000E to get the head back?

If you can bitbang with your lab version, it's worth trying. Look at address 6060 and ensure it shows value CD.

I checked my lab and it's 4.04.04. I get a runtime error when I press F2 to enter the service menu. Not sure if it is the computer or what? I'll test it on the 486 laptop.

Your radio & RIB are all connected and powered up before entering the BitBanger, yes?
