If you run the Flex 1500, 3000 or 5000 then take a serious look at what Darrin KE9NS has been doing. A few weeks ago I suggested a couple of changes that would improve serious DX chasing using PSDR...and here they are - suggestion to reality within a matter of 2-3 weeks....Darrin's SOFTWARE is DEFINING this RADIO !
"4/7/18 v188.8.131.52: New Quick "SPLT" button feature: Right click to automatically turns ON and toggles between a VFOB TX of +5khz or -5khz split from VFOA. AND: Setup->Display->Split TX Listen checkbox will automatically set the sub-receiver (MultiRX button) to the TX freq during the Split."
This feature adjunct with setting the VFO A/B audio balance/split allows you to listen to the DX in one ear, and the pileup TX-freq in the other! So, when you here the otherside of the QSO you know you are on the right QRG...time to call, and its also easy to track the next QSO/ split-movement etc.
This particular feature is a technique that some of us serious (aka obsessive) DX chasers use to catch a slippery DX fish where they are plagued with heavy pileups. When trying to use SmartSDR I had to set up macros in DDUTIIL and other workarounds. Now in PSDR its easy - one click is all it takes for me to be ready and on the DX.
I recently sold both my 2 x 6500 and reverted to using a trusty 3000 with PSDR - a decission that was to focus on what the radio actually does for me right here and now - to help catch DX.
