In all this discussion about matching, just remember that there are two
issues with antennas.
1. You have to get the power into the antenna by matching
2. The antenna has to radiate the power in a direction that will reach
the intended receiver.
You can learn a lot about your antenna by

I've not been happy with the audio since acquiring my Flex 5K. I've had
reports of distortion, noise and serious echo. I'm using Yaesu's MD-1 mic.
I've played with the settings and spoken to another user trying to model his

Check the mic cabling.
The cable shield needs to connect to the shield and pin 5 of the 8-pin foster
connector.
The mic (-) wire needs to be on pin 7 of the 8-pin foster connector and NOT

Obviously the mic (+) needs to be on pin 8 and PTT on pin 6.

I have not used a Yaesu mic, but in my experience if you are getting echo
there is too much mic drive in the line. You didn't say if you were using

I am seeking a used SDR-1000 QRP or maybe a 1500 if someone is upgrading to

This would be for secondary / transverter use, hence the QRP.
Early versions or more recent... either OK.
Please reply off-list with pricing, any particulars.
Thanks,

I speculate that the differences between spectral display methods are due to
design convenience and the parts cost of making it happen in each case.
Swept spectrum analyzer add-ons require the same sort of building bits
(transistor oscillators, mixers, cheap ceramic filters, etc.) from which
Spectrum analyzers display signals in the frequency domain. There are 2
basic methods of doing this: hardware software.
Traditional swept-frequency spectrum analyzers take a brute-force hardware

Assuming you've decided on Win7 (with which I agree wholeheartedly, but that

Nice explanation... but these other high-end radios all sport DSP's
too. So I suspect the answer has more to do with the memory required
to hold N-samples for an N-point FFT. All DSP's are quite capable of
doing FFT's, so there seems no other excuse.

I always assumed they were internally using FFT but the 'peripheral'
interface was a sweep because of the speed of the transport between the
radio and the display. Or the power of the dsp chip itself.

Hi Neal,
You might be correct - at least for some of the radios. But my Icom

I have found that the 8 pin connector even when wired per the manual is
more susceptible to RFI than the 1/4 rear connection for whatever reason.
Even though this is a balanced input it will work just fine with and
unbalanced microphone provided that the mike boost is checked in the menu.
