[R-390] OT: ARRL 600M experimental work

[Cecil Acuff]

Greetings Group,

        This is off topic for this group but I know the depth of this group 
and felt this would be the best place to field this request.  A local ham is 
a part of the 600 meter experimental license that has been issued for 18 
months to explore the possibility of spectrum there having some viability 
for Amateur use.  All the equipment is homebrew in the same spirit of what 
many of us knew back in the 40's, 50's and 60's.  I find the work 
fascinating.

I have offered to Pat what little I have that will help him out but he is in 
need of parts to build a PA that will work down in that part of the 
spectrum.  Pat has requested a desire to limit the weight they have to work 
with due to his age so large steel 19" racks are a bit of a problem.

Pat is  looking for the following in any condition or whatever can be made 
available to support this effort:

*    A cabinet similar to what an old DX-100 would have been in.  A whole 
transmitter of that sort with parts missing would be even a bigger help for
      parts. As I understand it coils and such at that frequency are large 
and efficiency quite low so a spacious cabinet is needed.

*    Used but working transmitting tubes...triodes like a 811's or what have 
you that will work GG....(I have offered a pair of 3-500 pulls)

*    Sockets to fit the above...(I didn't have those)

*   Maybe any old Commercial broadcast tank circuit parts etc?

*    HV/filament transformers that would be suitable for PA tubes offered or 
listed above.

*    Large filter capacitors.... (I might be able to fill that one)

This work is a labor of love and is on a shoestring budget and no telling 
what it might mean for the Amateur community in the future not to mention 
you guys that would like a group of weak signal targets to hunt for down on 
600 Meters.  Pat's beacon transmitter can be listened for on 505.6 KC (less 
than .05 watts ERP at the moment and that's with 80W into the coax) and if 
interested in finding out more about the project go to www.500kc.com

This would be a great chance to help this group out with some of the old 
stuff you might have laying around that you know you will never get too. (we 
all do it!) I would be happy to be the collection point and delivery guy for 
anything you might want to send to help Pat Hamel out (W5THT and WD2XSH/6) 
I haven't spoken to him about it but I expect he would be willing to pay for 
shipping if needed.

Please contact me off list about my address and any potential items 
etc...don't want to seem ungrateful but I also don't want a divorce due to 
my garage looking like Fair Radio's warehouse.

Thanks in advance for your help!
