Hi Dick,
I haven't seen anyone mention which devices they're using. According to
Wayne, there are two LDMOS devices "very conservatively" rated at 1500
watts output each.

I don't have those answers, nor am I a salesperson for the brand. But the
great thing about Elecraft is that you can ask the owners of the company
those questions directly and they'll answer. Perhaps you'll post their
answers.

## No mention of TX IMD..nor eff, or whether it can be run at reduced
power levels.
Does it use a slew of DIPLEXER’s, like the new flex SS amp does ??
Or just a slew of LP filters ?
## No mention of duty cycle. Will it run RTTY..or key down cxr at 1.5
kw ? How loud are those
3 x small diam fans ?
## at least it does have a sampled output for folks that have an ADAT
xcvr. They used sma
connectors for their main input for the pre-distortion scheme. The
adat wants to see no more that
0 dbm max....and -24 dbm min..... for the sample.
## the idea here is that The new KPA-1500 can be used with other brand
xcvrs, that do have a
distortion cancelled input. On paper, the TX imd of the KPA-1500 would
be improved by another
10-15 db.
