• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

I have tried to program the LPE200 to the 902-927 amateur band
and the radio is saying the sythesizer is not able to lock.
Anyone have any ideas to remedy this??

I investigated something along similar lines recently. I found the VCO was a limiting factor, only able to pull +/- 8 MHz from its designated bands. Since the VCO is a sealed surface mount device, it'll be very hard to modify. By all means, if you want to give it a go, let us know how you go about it.

This thread has a little more information, but its more about out of band RX only, where as you want to figure out TX side of things too: http://forums.radioreference.com/harris-ma-com-ge-ericsson-forum/195661-lpe200-out-band-rx.html

I think the TX side of things shouldn't be too hard, the RX front end would need some new ceramic bandpass filters though I would think - the existing ones are fixed & not adjustable. You might be able to modify the existing filters by adding in a little bit of ferrite in a weak glue solution (to go down in freq) or a little bit of brass (to go up in freq), I've done that to other such radios in the 450 MHz range before, but never tried it on a 900 MHz type.
