• 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.

Is anyone out there using NMO antennas for base use? I can't think of any issues that would arise with this but maybe there is. Any input?

No issues.

I've used these off and on for years:
LARSEN BSAKIT | Covert Your NMO or UHF Mobile Antenna to a Base Antenna - BSA KIT

There's also the cheaper "knock-off" I haven't tried:
http://www.amazon.com/TRAM-1465-Mobile-Ground-Plane/dp/B004PGMFGM/

-OR-

You can roll your own easily...
if you're a well stocked
electronics/radio parts hoarder like me.

Thought about using one of these and mounting to the outside of the house.

That bracket would certainly work but doesn't supply a ground plane. Fine with 1/2 wave, non-ground plane dependent antennas.

The base kit noted above would be a better choice.

Would it hurt anything having the antenna in the attic? As in hurt i mean would i lose any signal strength being in the attic?

It really depends.
Some home insulation uses a foil vapor barrier, this can block signals.
Some roofing materials may be metal, that can block signals.
Wiring and copper/metal plumbing in the attic can create issues.
Metal ventilation ducts can be a problem.

Really depends on the construction.

I've got a location at work where I needed to mount a GPS timing antenna. I didn't have any room on the existing masts, so I was able to mount it to some rafters. Since it was a composite roof with plywood sheathing, it wasn't an issue. The GPS signal is just fine under the roof.

For scanner listening/transmitting, you really want the antenna up high and in the clear if at all possible. I do understand that isn't always possible. If your home construction is right, mounting in the attic will work.
