    Chris. I did mention the German Kit amp you are involved with. You bias the BLF189s at 5 amps and it runs very clean, probably better than the PG XL which is a pair of NXP150H @ 4 amps. My observations with other LDMOS amps include the Elecraft KPa 1500 which I have seen theee on the air. While I do not know what bias they use of three people I know who have them one is clean running around 800 watts (his normal output) and two were not as clean with comparative signal strength (both driven by non-SDR radios). The single device LDMOS device amps appear to not be as clean at their rates power out. I can attest the SPE 1.3k/fa @ 1300 watts is not as clean as the PG XL @ 1500 watts. This is due to a number of factors. I have not lab measurements but just my observations. Again, your RF Kit 2k+ is very clean. Dave wo2x
