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.

30amp would be comfortable for me personally.

i ran a vhf 110 watt astro here in the house (i set up the h/l button for high/low power,dont know if a spectra can do that)
and ran it off one of those 30amp switchers they use for led lighting
worked fine
but i now float the ps across a lawn tractor battery
it lets me draw heavy loads with out heating up the ps and having the fan run all the time
im thinking about getting another supply to parallel the first as there are plenty of other radios and things on that system as well

Spectras, Astro Spectras, draw roughly 23 amps for 110w units. Lowband X9000s are capable of drawing even more. A 30-35 amp power supply would provide sufficient overhead, however, the suggestion of floating a battery or 2 (preferred AGM non-venting types) is the best solution.
You can find plenty of things in the shack to run directly off of 12 volts, and adding a solar panel or 2 would give you a very nice emergency station also.

Mine would blow 25 amp fuses, so I needed to use a 30 amp fuse. So it seems these radios draw more than 25 amps. A 35 amp Astron linear supply only delivers 25 amps continuously, so make sure whatever supply you use can deliver at least 30 amps all day long. Most supplies are rated in peak power, not continuous power. I figure the 50 amp Astron linear supply which delivers 35 amps continuously should work.
Good recommendations thanks everyone,
