I sugest that you might read the ALS-500 manual, it says in the first paragraph that it covers the full frequency range from 1.5 to 21.6 Mhz, and looking at the front cover, that does seem to be the case.  It's not too hard to get 500 watts out of an FET these days.  Tokyo hipower is producing a legal limit solid state amp, and I know for a fact that the design they use can operate on 5 Mhz.   As a second fyi, I have an old 3-500z amp from Amp Supply, and just playing around, I could tune it on 5 Mhz pertty easily by selecting the 80 meter band select, and I could get about 900 watts into the dummy load.

actually, I ran this thread idea past one of our state MARS nets Tues 
and got several people wanting to be kept abreast of what I found out, 
etc.   As I stated in the beginning message for this thread, I would 
like to ask the list membership here to understand what we are wanting 
which is a broad tuning amp, preferably solid state for its mobility for 
base to mobile to portable set up and back again, and capable of running 
legal limit since it would be used for 1.8 - 30mhz. Continuously.

Problem is, nearly all amps out there are HAM BAND tuned.  MARS as most 
or all MARS members here know, operates on a bandplan outside of the HAM 
bandplan. Including bands from which hams are excluded. Such as 
10-14mhz.  This amp would be capable again, of operating on all HF bands 
to help the member or affiliate to justify the expense of the amp - he 
would be able to use it on ham bandplan also.  So, a SSB, at least 1kw 
output, full HF bands and solid stste.  isfai am concerned, it would be 
a 110VAC so that it would run off an inverter in the field or, mains in 
base mode.

I would then like to ask the membership to design this and help me to 
find someone who would be willing to build as many as 5,000 of them or 
as few as a 100 or so.  price should be held to a $1 per watt or less if 
possible.

We have more than 5,000 volunteer affiliates now and I think that a lot 
of ARES/SHARES, etc would be very interested in such an amp.

I really believe that there is a market for this amp if we can get it 
into production.

I am not even about to try to build one from a kit even<G>  I know 
enough to electrocute myself trying to get it aligned or whatever that 
is called today.

thanks for your interest and reply
