etc. I bet there are way more kits today than there were during the
Eico Heath days. They just aren't for shortwave radios very much,
although the Elecraft radios are the best in the world and totally
suitable for serious SWL.

While the Elecraft radios can and do perform well on shortwave, the
widest crystal filter at 4.2 KHz (on the KX3) is still a bit narrow for
real hi-fi SWL. I say this as a very happy KX3 owner.

It gets the job done, but the Elecraft rigs are really meant for hams
and not SWLs.


I have a K3 and you can get any width filter you want, use an FM filter
for AM, etc. The K3 can be configured for space diversity. The K3 has
synchronous detection. You need to add a set of General Coverage
bandpass filters for listening outside the ham bands. Even with all the
necessary accessories it still costs less than a comparable Ten-Tec.

Just looked at the KX3 schematic. It is a direct conversion receiver. Where is the crystal filter located ?


There is an 8 Mhz i.f. in the K3. I don't have a KX3.
