I understand that but my point is that there simply is not anything out
there betwee 3.2 and 29 mhz portable for a kw+ for any price reasonale
to a volunteer and I think that includes both tube and SS.
Almost all are less than 800W. Tom's ALS600 is still that, NOT 800W+
This MARS amp to be really popular is goiong to have to be a 1kw to make
it interesting enough for the affiliate to be willing to buy it. He is
going to want to use it for MARS at a max of 500W but also to be able to
go to Ham bands and work Dx with at least 800W.
Really, this is so reminiscent of the discussions of the perfect
rifle... what it should be to be able hunt anything from prairie dogs to
Elk or moose. simply stated, there is no such thing as a single rifle
for all that different game anymore than I am going to find a single amp
for a reasonable price for continous tuning and 1kw.
$2/W is more reasonable a price but that is a lot of months of
discretionary money being saved and being hit here and there for
repairing the plumbing, or the car, etc. Also, it is one thing to save
a thousand dollars but a multiple starts getting into shoulder shrugging
and trying to find something barely fits any requirement.
We just may have to find some way to subsidize the purchase but first,
we are going to have to find what we want, being manufactured now.
Lets face it, we do not want to take a Quadra or an ICOM version of same
in the back of your mobile cross country while trying to operate it on
the road. And I doubt that any of those meet the band requirements
anyway. Have looked at so many specs in the last couple of months,
that they are confused in my mind. wish now that i had made up a
comparison chart before i started looking at models.
Still, I really do appreciate your reply and time, kind consideration as
well as that of Tom and others on this reflector. I am not giving up
yet hihi
