Hi Lee Thats why FT2000's, Icom 7800s, 7700's and most of the 200 watt radios are selling so well to contesters and Dx'ers, even with a much poorer receiver than the K3. The importance of a 200 watt radio for many who run older style high drive amps is a deal breaker. Who is going to rebuild

Re: [Elecraft] K3: DRM listening?

2009-12-11 Thread Paul Christensen
Some DRM modes are narrower and can be accommodated if the FM roofing filter (nominal 13 kHz) is installed. But getting the IF output to the DRM decoder still requires modifications to the K3. DRM decoding with the K3 is easy with the SDR-IQ together with SpectraVue, VAC and DReaM software.

Since the K3 (like virtually all current rigs) has fixed-tuned output filters, the match to the finals (and so the efficiency) will degrade as you go beyond the output power (and so impedance) for which they were designed. That means more current demand, more heating and perhaps new final

2SC2782 is rated at 80W min each at 175 MHz so getting 150W from two on 1.8 MHz should be peanuts; the main reason why they are restricted to 110W in K3 is linearity (across bands) + component ratings. At higher power, the efficiency can be higher and thus K3 may actually run cooler!

Just for the record, 150 watts is actually closer to 1.8 dB over 100 watts. But regardless, it is interesting to consider what it would take to realize this increase on 160 meters. The movers and shakers on this reflector have eloquently made the case that 1.8 dB really does make a difference
