[Elecraft] kpa1500?

[Jack Brindle]

Hey Vic;

Hope you are enjoying life in Israel. Someday I'd love to visit the country. Strange not having you over here, though.

As for the original KPAs, I can assure you that at this time there are no functional units. There are a lot of wild rumors on the list in this topic, most very much untrue. But, I will also say that the KPA500 contains a close derivative of the firmware from the earlier effort.

And yes, the older units were beasts! Carrying them took a bit of effort!

73!

I was told later that there was no problem with performance or FCC specs. They simply wanted to concentrate their resources into the K3, which had just come out. The projected price, though, was WAY above $5000.

Still, when you're cranking out KX3s and K3s and P3s and KPA500s the way they are, does it make sense to build up production facilities for a couple of hundred amps a year?

It would seem that the now extablished 1000 w devices could form the basis for a commercially viable amplifier. Perhaps no one else is interested, but I wanted to ask if such a product is even on the "consideration" list?
