    Well, double the power (100 watts to 200 watts) is a 3dB increase, only 1/2 S unit at 6dB per S unit. So from S7 to S7 and 1/2. Not really as much increase as it sounds like. From 100 watts to 1000 watts (10dB) is less than 2 S units increase.

    Based on that and Tim's presentation the cleanest and loudest gets noticed so 1/2 db may make a difference without the 1500 watt @7000.00 Thanks

    Doesn't Yaesu produce a 200W unit -- the FDX101-MP?

    And, as John pointed out, the extra power doesn't really translate to increased contacts/readability in tough conditions. I find the DX+ compressor cuts me through pileups quite well. (Plus a bit of patience and persistence :-))

    Don't forget about Flexs' inclusion of Controlled Envelope SSB! It is one of the lessor known and touted feature of Flex radios now.

    It is the CE-SSB speech processor feature that can produce nearly 3dB of effective gain. I think it is actually closer to 2.8. Check it out.

    If CESSB is something new to you, read this

    After reading the QEX CESSB piece, I would like to know if CESSB is always enabled or is it a selectable function on my Flex 6500. Any feedback on that question is welcomed. I could RTFM but I imagine it is buried in the details.

    Yes, it is in the manual. :) Would you like me to look it up?

    Mike, is this the 3 settings of compression, normal, DX and DX+ ? Or is there some other setting? If so, is it on by default or must this be selected? Many thanks, Jim

    Thanks, Mike. I understand perfectly now. My AM ragchew group reports it sounds best for that mode of operation with the compressor on but set to Normal. Makes sense. 73, Jim

    most every time anyone mentions 200W capable rig, the responses are "the extra power doesn't really translate to increased contacts/readability in tough conditions".

    while it is a true statement regarding ordinary operating modes like Phone, CW, and RTTY, it is not an entirely true statement regarding digital modes - especially those modulations with a high crest factor. ALE and other digital modes offer increased range with only a couple more dB S/N and transmitting key-down time can be increased.

    the Kenwood TS-480HX was the EMCOMM 'go to' rig because of the 200W capable PA: endurance, headroom.

    = 73 = KB3CS
