• 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.

My Larsen has plastc base that whip goes into. My question, and a 144 2 meter antenna, or 150 band antenna, be shortened for use in 220 withoit issue, or is there a loading coil that would prevent this. These are single band antennas. Thanks.

This is the NMOQ base. The NMOQ is metal and the OP says he has a plastic base, so I don't think he has an NMOQ. There is also a black version:

This is the NMO150B base. There is also a version with the same base, but a chrome antenna whip.

There is also the NMOWBQB which has a plastic base:

People have done that but the matching coil for a 5/8 wave VHF is a bit too large for 220 and the whip would end up shorter than ideal.
Thx, was just trying to avoid new purchase as have several i could cut.

All of my NMO-Q antennas have a plastic base not a metal one:

My base looks like the NMO-150B base, guess I could cut one down and see, but once I do if it fails then Ive wasted the whip.
