I do not think I saw these questions answered on the Elecraft site or KPA1500 FAQ.
The KPA1500 price at $5995 is "introductory" which implies a potential for a price increase. I suspect it will be based on supply/demand. Can you comment further?
I read there are plans to offer the KPA1500 in kit form. I suspect the price differential between factory-assembled and the kit will be ~$200+ (maybe more as the KPA1500 is more complex and has a higher overall selling price) which is the difference between the factory-assembled and kit versions of the KPA500. Can you comment on this as well?
Lastly, can you provide detail on the low-pass filtering design in the KPA1500. While I am sure the amp meets FCC specs, I am curious as to how Elecraft has elected to deal with the known large odd harmonic spurs from the LDMOS that would typically be reflected back into the device.
Thanks and 73--
