Tone tolerance should be around 1%; Exact is better, but anything from 1431 to 1435 should fit the tone mask. I see very few consoles (including my own aging Centracoms and Zetron 15's) that stay within a 1 Hz tolerance window. Record the audio off the air and use Audacity to see what it is really doing, including tone duration. You can also download page audio from Broadcastify if the feed is available. Program the decode to the real world, not what 'they' say the console specs are.
Scanning a page channel in 2Tone doesn't work even when the paging channel is priority. A priority scan tells the radio to break away and re-check the priority channel every X seconds. That can interfere with the unbroken tone period specified in 2Tone Code CH Notone timer. If the radio starts to decode on CH 2-1 "PAGE" then priority kicks in and it switches to CH 1-1 "EMR-1" even though the freq is the same the radio re-locks and the tiny drop will invalidate the decode.
The best most perfectly aligned F50 is still not the whippiest scanning radio. I see that the Scan Setting Timer Fast Scan and Slow Scan times are no longer default in either radio. A 0.025 Fast scan it way TOO fast to get a good lock unless the radio is perfectly aligned, the CTCSS/DCS decodes are disabled, and the planets are in optimum positions. Set Scan times back to the default 0.100 and 0.500. 0.070 is the fastest I have ever been able to use reliably.
I normally program a special channel called "QUIET" that is always muted until signaled. Set the radio on that one out of scan and let the radio alert. Night/Off-Duty/Wife approved, and good for pocket carry. I do not use any Rx CTCSS and inhibit Tx to prevent butt dialing. That is much more reliable; All the radio has to do is act like a pager and listen for audio tones on one channel.
Something you can try is to change the memory channel 1-1 line to remove the 114.8 Rx C.Tone. Leave it on Tx. I seem to remember something about 1433 not playing well with 114.8 CTCSS in some radios. It's a harmonic thing.
In the 2Tone Code CH you should change the 1st period to <0.6 and the 2nd to <1.5 seconds. The default seconds means that the radio must hear a full 1.000 seconds of the A tone and 2.000 seconds of the B, something that the console or base station may not be putting on the air. You should try extending the NoTone to 0.160; this is the space between the A and B tones. Again, the console may have issues.
A final trick: 50's with a broken 9-pin can sometimes be coaxed into cloning by flexing the connector forwards or backwards when reading/writing. If it starts cloning, don't breathe until it is done. It's a PITA, but works 90% of the time.
Hope this helps.
