The SPE 1.5 uses a single LDMOS device. While it can produce 1500W with sufficient drive, it starts to compress well before the 1000 W level. SPE's own test data supplied to the FCC showed very poor IMD characteristics - what one would call a distortion generator - at "full" power. 73, ...

The one piece 10kg lightweight design and a multi-voltage power supply make the SPE 1.5k-fa very nice for travel. I do not recall reading what transistor(s) it uses or know how loud it is or what the IMD is. The Elecraft KPA-1500 is pretty heavy-duty and of course well supported in the U.S. John KK9A Dave n8ag at comcast.net I'm trying to decide on a SS amp. I already have the KPA500 and love it but the price for the KPA1500 is a bit above my budget. I am looking at the SPE 1.5K-FA which is about $1000 less. I like the fact that it has inputs for two radios and 4 antenna connections. Plus the power supply is built into the same box. I know the response from this list will be pro Elecraft but any constructive or informative comments would be appreciated. Tnx es 73, Dave N8AG Sent from Mail for Windows 10
