Has anyone here built their own shortwave receiver? Something comparable

low-end commercial receiver, (perhaps no FM though) no audio amplifier

either. (Just pre-amp) Something very modular so you could experiment with
filters and things along the stages.

I tried to reply off list- but looks like you have an anti-spam address.

Yea, I do. Anything to this address gets a higher "spam score".

Lots of people are building their own receivers- and many of them above
average designs.
I have posted this before, but here it is again for those that may have
missed it:

5/2.5/.5 KHz homebrew xtal filters; selectable and defeatable AGC; tone;
audio notch filter; preset BFO for USB/LSB/CW; AM detector; S meter

Loosely based on W7ZOI Progressive RX from the late 1980's.

Look also at Pete KE9OA's neat receiver on his site and many others.

I couldn't find Pete's web site? (I did a google for KE9OA)

Would you say it was rewarding to do something like that? What were the costs
and such?

Did you build the case yourself too?

Seems like it would be fun to do something like this, but whew! where to start?
