[HBR] what is the BEST receiver

[DW Holtman]

This might seem like blasphemy on the HBR furum, but here goes. If you are 
looking for a fairly simple very high performance receiver that is optimized 
for one band. Take a look at Direct conversioon phasing receivers. There is 
a ton of info on the net. Google KKB7, Rick Cambell. His design, rivals the 
best Receivers available today, without all of the bells and whistles. I 
have built a couple of them a while back and they really do work. The 
opposite sideband supression is better than virtually all of the comercial 
receivers that you can buy
