What program do you use to create Voice announcement files

We were using a free site to create voice announcements for MOTOTRBO 2.0 radios (CP200d, XPR3500e) but that site has some security issues.

What do you guys use to create voice files that aren't huge (CP200's don't have a lot of memory).

Thanks in advance.

No.

You have a choice of high power and low power. You can set each personality to either high power or low power.

Unless these are the only frequencies in a certain frequency segment in which case you "might" be able to play with the tuner for that frequency segment.

Re: LTR no handshake

LTR data levels are fairly critical. Are you running wideband or narrowband? Narrowbabnd LTR levels ate 700 to 800 Hz deviation. The LTR data from the controller to the repeater needs to go into a flat audio input, typically DC coupled.
