[HBR] HBR 16

[David Newman]

Bill,


Thank you for response.  I very much would like the templates.  But I 
have done pretty good looking at pictures.  If you recall the one 
kilowatt one band amplifiers in the ARRL Handbook, during the 1960s, I 
liked their layout of front panel.  So I made my best estimate, and 
reproduced some of them, and made  modifications.  I always liked the 
single band kilowatt concept because it lent to ability to modify 
design.  I changed the PI network output to a PI-L network.  PI network 
gives about 35 dB attenuation on second harmonic, whereas PI-L gives 
about 52 dB.  I also built a four tube (813s) amp for 160 meters.  Some 
photographs are at:

It would be nice to see exactly how the receiver was laid out.  I plan 
incorporating some of the modifications that came out in the 1960s.  
Also, I want to have band switching built in for 6 meter converter, 2 
meter converter, and maybe 1 3/4 meter (222 Mc) and 432 Mc.  Thus, I 
want my "dial" calibrated for at least 6 and 2 meters.  I think it would 
be neat to do some 6 meter sporadic E, or 2 meter moon bounce, with HBR. 


By the way, I had the pleasure in high school to live near QTH of Sam 
Harris W1FZJ.  He then was editor for QST World above 50 Mc.  He was 
very friendly when I visited his QTH.  We did some interesting Saturday 
or Sunday afternoon projects.   For example, one visit we  made 
polarplexers for 10 GHz, using  reflex klystrons, a pipe for waveguide, 
and 1N23 diode.  A "flying saucer" kids used for sliding on snow made a 
good  parabolic reflector.  I learned a lot that day about microwave.   
Well, that was my first HBR for microwave. . . . .


I found my Eddystone dial.  It seems a lot easier to use a National 
Dial.  Is there any real advantage with the Eddystone dial?   I am 
debating which way to go.


I have enjoyed reading the many posts on this reflector.


73,
