[Repeater-Builder] Re: 6 Meter RF Amplifier (PA)

[skipp025]

Hi Bill, 

Yeah I'd also seen that Monster PA listed... 

For me, somewhere above 100 watts heading up toward say 
300 watts is a place where all the related hardware has 
to step up to the next level/size. Circulators, combining 
equipment, amount/number of cavity filters, the power 
supply and most important reliability of keeping it 
all going. 

Detection and damage prevention in fault or failure modes 
becomes a constant background through process not so easily 
avoided when using lower power levels. 

I'd have loved to had that Quintron 4-400a tube PA for 
a 6-Meter Repeater... but that's a lot of working electronics 
to park at a remote mountain top where maintenance might 
not be as regular as one would hope. 

When it comes to solid state PA's... I have a hard time 
finding and keeping decent power supplies going. All those 
switchers we find surplus new-old-stock seem to last a 
year or two at most before failing. I guess it's time to 
spend more money on better supplies. 

It would be nice to have a walk tall, step flat (jargon 
from another radio service) repeater signal but it's 
hopeful the repeater would be able to hear at least as 
good at it talks. All mouth and small ears... an 
alligator machine of which we seem to already have in 
abundance. 

cheers, 
s.

 How about this PA on ebay? Item # 330387252314
 Larcan solid state PA does 600 watts FM and about 1KW on SSB

 Hi Paul, 
 
 We're talking a repeater site type of amplifier... why 
 would I/someone want to heat a Repeater Site?  Even with 
 someone working in the building?  Those technical guys 
 don't deserve any creature comforts... 
 
 :-) 
 
 Besides, the normal building heat is propane.

    I'd love to have this PA just to tinker with... but I'd 
    hate to be the one paying the site power bill. 
  
    6 Meter Quintron Transmitter, PA Deck 
  
    Ebay Item Number: 160389525215 
  
    ... and hopefully one would not have to pay for the 
    extra real estate (cabinet space) this baby would fill.

[Repeater-Builder] Re: Any Repeaters Taken Off Air Permanently?

[w6nct]

Hi Tony, 

I'm curious to know why you are asking (but admittedly I haven't read the 
entire thread yet, maybe I just missed the reason...)?

But to answer your question, I/we have one that isn't quite off the air (yet); 
but as the primary Trustee, I am considering doing so, if I cannot retarget it 
and/or the site.  

As a little bit of background, quite a while ago a bunch of us got together and 
put a 70cm box up on a local mountain.  At the time, there was a need for an 
open box serving the area.  Without going into all the painful details, we 
ran into a lot of problems getting it coordinated; and before it ever happened, 
a local repeater club put one up (too close to ours to make ours necessary 
anymore).

For the past several months I've been pondering what to do with the site, 
equipment, and all that goes into having such an asset; and while I/we haven't 
decided completely, retargeting seems the most viable option (if I can find a 
better band or application for the terrific high-level site).

I'm open to suggestions, if you have any that still serve the intended goal of 
in some way helping the local Amateur Radio and/or Emergency Services 
community.
