As a "casual" operator, I probably will not use it much because the bandpass filters already implemented in PowerSDR are so good. I have yet to experiment with the revised ESC as I really do not have a good second antenna to use with RX2 in the 5K.

Very distracting. Not that I use FM often but when using the Flex remote with my iPad, it's sometimes nice to get into the local repeater when I'm on the road.

Perhaps 12 dB is not enough attenuation or perhaps the equalizer does not work when you are in the FM mode. This is not a "show-stopper" as I am rarely on 6 meter FM, but it is a bit distracting. This would probably be an issue with the 2 meter and 70 cm transverters (VU5K) as well, but I cannot test that setup (at the moment, at least...still thinking about adding this capability to the 5000 some day). > > > Ed, K0KC > > > > ________________________________ > From: Ross Stenberg <ross.stenb...@charter.net> > To: flexradio@flex-radio.biz > Sent: Sunday, August 21, 2011 9:14 AM > Subject: Re: [Flexradio] CTCSS > > Most FM ham transceivers don't have the audio and especially speaker systems to reproduce PL tone frequencies. The Motorola speakers used commercially were designed to pass mainly the most intelligible frequencies of the human voice. Flex users typically have more full range speaker-audio systems attached and are capable of reproducing the PL tones. Try enabling the receive equalizer and cut out the low end. > > 73 Ross K9COX > On 8/21/2011 6:31 AM, Ed Wilson wrote: >> Colleagues, >> >> I finally got around to playing around with the FM mode using my Flex-5000 >> on six meters yesterday.
