[Elecraft] Sudden KPA1500 power reduction

[rocketnj at gmail.com]

1. Depends. My KPA1500 has same NXP 1K50H devices as my PG-XL. (yes, I have
both). I heard some KPA1500s had different devices than the NXP but cannot
confirm that

2. Yes. Shipping for a while now.

Here's my comparison of the two since I own both. The KPA1500 fan noise is
better to my ears sitting on the desk 4 feet from my operating position that
the PG-XL. I use the 1500 at home while the PG-XL due to its LAN integration
to the Flex radio is at the remote site 20 miles away.

Both are great amps and with the last updates done to my KPA1500 a little
over a year ago it has been trouble free.

Just curious, does the big FLEX amp use the same two LDMOS devices?
2nd question, have they shipped any yet? (probably not the right place to
ask)
