Ht1250 cut off transmission

[Cmalan1213]

Hi guys,

Sorry if this is a repeat, however I have multiple ht1250s and whenever a unit attempts to talk it takes a while for the frequency to open and transmissions are heard. All radios are programmed with the side tone so I know its not a user issue. When im in the same room as my scanner the scanner not scanning a Pl catches the whole start of the transmission. The issue is when people are having short transmissions some times all you will receive is a click. Is there any way this can be changed? frequency is in the 450s with a DPL tone.

Hi - A few random thoughts...

Any difference when scanning is toggled on versus toggled off?
Any difference on direct simplex comms versus repeated channels?
Any difference in monitor/CSQ mode versus DPL mode?
Any difference on a channel where no MDC signaling is used?

No real difference when scanning, simplex channels with MDC on are fine. The receive radios use MDC but the other company on our frequency does not use MDC and they are who we have a hard time hearing.

Is the DOS Squelch timer on? I turn it off and you will hear the MDC chirp before the incoming message.

Bingo on the DOS timer. I ALWAYS keep them set to zero. They cause more problems when a non MDC radio is used than you can imagine. So what if they hear a little bit of the chirp.

Thanks guys, DOS was set at the default of 500ms. I have shut it off hoping it will help.
