FCC Menu & LPE200

[mitaux8030]

Hello all,
I'm trying to get the FCC menu working in my LPE200. Its been activated in the menu list, and diagnostic mode tick box checked under diagnostic options. Selecting FCC Menu results in nothing more than an error tone.
I'm using P1R17B03, and can see that FCC menu items are buried within that flash.
So what am I doing wrong?

Don't know a whole lot about the LPE, but from my experience with the M-RKs, the amount of RAM onboard has a lot to do with that kind of stuff. Similar to how 256K radios cannot decode the Features list into a 01 02 03 etc form on the radio. I am thinking this is the same kind of situation, the code is in the flash but the radio simply doesnt have the horsepower to run it.

I've seen this in operation on known 512k LPE200s (1997 vintage) before, so it shouldn't be a limiting factor.

Interestingly, ProGrammer mentions that the FRQ EDIT menu option is a feature encrypted option, meaning you'd need option 34 (direct frequency entry) presumably.

Now for FCC MENU, ProGrammer doesn't mention anything about it being a feature encrypted option, but I now wonder if FCC MENU needs option 18 - Test Unit operation - at least on an LPE200?

Thats a good question about the Feature 18. Both my radios have it, and they both function with the FCC Menu. I have an old UHF Orion laying around with the bare-bones features ill fire that up tonight see if it works or not!

The test radio feature has nothing to do with the FCC menu. An Orion or M7100 with that feature is designed to be connected to a GETC or SitePro controller at an EDACS or P25IP site to do periodic testing of each channel and its' high speed and low speed data. Obviously, the Orion can't be used as a P25IP test radio.

The FCC menu is not supported on the LPE-200 radio even though you can make it a menu item.

Thanks for clearing that up greenthumb... but I've personally seen a LPE200 with some sort of FCC menu functionality - a CC / working channel display and a level display in dBm. I just assumed that the FCC menu was what activated that functionality.
Perhaps it was activated via some other method, like a custom flash (a la T99 for the MRK or Orion) or a SC4 file.

depending on version programmed, try holding 2 top buttons when radio turned on (no ptt) unlike the programming mode.

Hmm OK, with P1R17B03, the screen flashes all dark but then goes through the normal PUST and a key held error. Invoking FCC menu still produces an invalid tone. But the fact that the screen flashed all dark briefly with this key combination possibly shows something different about the power up config. I'll have to experiment a bit more.
I note the emergency button and top side button held together, as well as M and a few other buttons do the same dark screen flash too... hmmm.

[mitaux8030]

Still no luck on this, though going through the flash code, I can see the embedded text for the FCC menu functionality in there... so I'm guessing it's all there just waiting for some trigger to activate it. Just a question of what, and how...
