Helpful Tips for Programming HT/CDM series

Taken right off the M website. Many people know these things, but it can't hurt to try & spread the knowledge around.

In an effort to assist you in the optimal programming of your customer's HT750, HT1250, HT1250LS, CDM750, CDM1250, CDM1550 and CDM1550LS radios, we have listed a few programming tips. The following suggestions will assist you in improving the functionality of our customer's radios. Please note that these programming tips may not be applicable to your particular customer's requirements:

Applicable to Portables and Mobile radios

If you are using Post PTT ID, you may want to decrease the DOS Auto Mute Duration to 25 ms (found under MDC System, DOS section). Also, if you are using Post PTT ID, you may want to turn off Tx pre-time, and set it to zero (found under MDC System, Advanced Section). This will help to make sure that the initial transmit is not interrupted.
De-emphasis and Pre-emphasis should always be on except for unique special applications. (Found under Conventional Personality, Advanced section, Emphasis section).
Suggested mic gain settings (found under Radio Configuration, Microphone section) are: 25.5 dB for the microphone gain 16.5 dB for the microphone gain in noisy environments 28.5 dB for the accessory microphone gain 35.0 dB for the microphone gain in emergency applications (enables hot-mic feature)
Full Compression and Full Expansion should only be used when all radios in the system have full compression and full expansion enabled (called X-Pand on 1225 Series radios)
Don't forget to complete the personality assignment to a zone!
Only Applicable to Portable Radios

If you are working in a high noise environment, you may want to disable Low Level Expansion. It is found under Conventional Personality, Advanced Section, listed under Expansion Type.
Only Applicable to Mobile Radios

Backlight: It should be manually set via the programmable button. Once the backlight is adjusted to the desired level, it will automatically remain at that intensity upon power up.

yes, thank you very much. this takes away a lot of guesswork that I was wondering!

Man, I had forgotten I even posted that.

A good time saving tip is to go into the program's options. There you will see where you can set the software to do several different things such as always copy the same frequency you entered in the RX field to the TX field, or you can define an offset...handy if your channels are primarily repeaters. You can also set it to always copy PL/DPL. This can potentially save a lot of typing.

Another thing I do a lot is use the 'tab' key to move around within the conventional personality page. This is a lot quicker than using the mouse to click on every single programming field, and I can leave the mouse pointing to the 'next' arrow to quickly move to the next personality.

Combine these two things, and you'll really be able to fly through your programming.

yes, I do that a lot. Tab key helps in a lot of different programs. The offset is good for UHF but for VHF really the only thing that helps is the DPL/TPL unless you're doing a lot of simplex channels. Since the VHF Tx normally aren't 5hz off

I wish Moto would do something like I did in a program I wrote. I made a little database to keep track of radio programming, on the left there's a place to put in the RX freq and PL, the TX freq and PL are on the right. Between them is a little copy button, like the 1225 software has, except that when you click it a floating menu pops up that lets you pick an offset, either simplex, +5, -5, +3 or -3 KHz. Would be great for those 450-512 radios where you have a mix of 450, 500, repeater and simplex freqs instead of having one fixed offset.

You're all witnesses... I'm claiming this idea... if it suddenly appears in the next version of CPS I want some money from big M!

Well I'm sure that you're not the first person to use that idea but as long as it works for you and makes your life easier, keep using it. Yes, if the big /\/\ decides to use your idea, they better pay ya!
