Can someone compare the above receivers or direct me to a site that does?
I am interested in buying one of these and need to make a decision of which one does what.
I did look up the reviews on eham. It was good but lacked a bit of comparitive info.
Thanks
A major difference is that the 170 and 180 have a third IF at 60 KHz.
This IF is tuned to 455 KHz, the second IF with a VFO. It has single
sideband with various bandwidths from .5Khz to 3 Khz. If I recall
it has a product detector.

The 170 is Ham Bands only, but it is prior to WARC.
The 180 is General Coverage.

The 145 is General Coverage. I remember its being a dual conversion
receiver with a crystal filter.
