Following up on my comment that
I have noticed that the Freq reported in MAP65 is 4 MHZ off. I have
Linrad set to 28.130 and Fadd to 116000.
Joe says" I don't understand what you mean. What reading is 4 MHz off?
I am running 2 set ups for testing and switching back and forth. A
TS-2000 running W6JT and a Dem 144/28 into the SDR-IQ/MAP65_IQ. Ans
using the MAP65_IQ simply as a bandscope at the time.
On the MAP65_IQ set up, the Freq reported by the Band Map and Message
Windows read 4 MHZ higher the then the read out on the TS-2000 for any
given decoded signal. Its is also 4 MHZ higher then the Frequency
reported for the caller on the logger.
Did I set up my Fadd wrong?
Joe, thanks agin for a wonderful program!

running on only a P3 1,GHZ with 512 MB. 512 MB may not be enough
memory. MAP65-IQ itself needs about 300 MB. > I have not been able to

limited processing power ? MAP65 has no adjustable settings that
affect decoding, other than QSO frequency and Tolerance. These afect
only the decoding that appears in the main text window. -- Joe, K1JT
