among others, sells an amplifier tuner pulser designed specifically for that
purpose. The added feature to PowerSDR would be great, but the hardware
solution may save an amp or two while we are waiting.

The setup data file for my SDRDataTransfer utility has been updated for
PowerSDR v1.18.0, including the new tables added for the FLEX-3000.
Please update your setup data either by using the update facility built into
the program (preferred) or by downloading from my website:

Mike,
It was not really an official ruling, but rather a letter from Riley
Hollingsworth, the special counsel for amateur enforcement, expressing an
official opinion that ESSB was an inefficient use of bandwidth and therefore
"not in accordance with good engineering practice". This phrase is used
Eric,
Thank you for setting me straight.

Subject: Re: [Flexradio] FW: Flex3000 SSB TX bandwitdh ony 3.65K ?
Actually, there is a limit
Stig,
You may have misinterpreted the FLEX-3000 specifications. The spec says,
"Flat Response 10 Hz to 3.650 KHz (SSB)". This means that the audio
response is flat within that range and no guarantees are made outside of
that range. It does not mean that the TX audio is limited to 3.65 kHz.
