TK-5720 $F7E Question

[devicelab]

Has anyone seen any issues with the TK-5720 decoding when using a mixed mode receive using NAC $F7E?

My VHF unit is set up to receive our state patrol which is on P25. Since all areas use the same "car to car" frequencies (with different NACs) I should be able to program them using the F7E NAC code. Also since analog hasn't completely disappeared I set the channels up in mixed mode with CSQ and NAC $F7E (and $293) for Rx and Tx.

However, on these channels I end up hearing the P25 hash and not the decoded P25 audio. No these are not encrypted signals.

Any ideas?

That is the latest.
You may have to strap 1 zone P25, and 1 zone analog. I have seen this on my 5700 where I run mixed
and it does not latch in on P25. I will look in my 5700 and see if I can duplicate it with my monitor.

Thanks for checking. I would do the same but I don't have a VHF P25 portable at the moment. I'm going to verify that analog works on the mixed mode setting but I'm pretty sure it will.

I can say that I don't have any problems with P25 channels working with analog channels and vice versa [in the same zone.] It's just when using the "mixed mode" channel setting.

PS. On a slightly different subject, is there a maximum number of channels in a single zone? I have over 100+ channels in my first zone and I often wonder if the radio is ever able to cycle through each channel. A lot of my channels can be encrypted so it's not as easy to tell. I can do a simple test for this though -- at least on the analog side.
