[HBR] questions about HBR-11

[Joe LeKostaj]

Howdy. I've got a few questions about the HBR-11 that I hope you 
who've already been down this path can answer.

1) Can I use the relatively large IF transformers (85 kc) from a 
BC453-type receiver in the HBR-11 rather than the smaller 3/4 inch 
transformers originally specified? In other words, was size the main 
reason for using small 3/4 inch transformers in the original 
HBR-8/11/13 article?

2) The HBR-11 uses three transformers in the 100 kc IF. Can the one 
BC453 I've got provide all three transformers or do I need a second 
BC453 to have enough of the right type?

3) Has anyone made a 30 meter coil set? Are there any birdies or 
nasty image responses when using an HBR-11 on this band?

4) Pictures of the underside of the HBR-11 show that L4A and L4B (the 
1610 kc IF transformers) do not have shield cans. Is that really how 
they're supposed to be?

5) Has anyone experienced direct IF pickup of the AM broadcast 
stations that are now found between 1600-1700 kc? (I suppose one's 
proximity to such a station would be the main culprit.)

6) It seems the original article did not call for a chassis bottom 
cover, is that correct?

Hoping to build an HBR-11 one of these years.....  ;-)
