No need to go to Rhon - they currently ship 25g sections 
with SAE 5 grade platted bolts.  You can get these
at the local hardware store.

Trinidad and Tobago - North America or South America ??????

While at VE5RI's WPX-SSB effort, VE6EZ mentioned that he had been to South 
working in Trinidad and Tobago. I quickly shot back that 9Y4 is not in South 
And then the fun began.  We encountered conflicting information.......such 

For the "South American" position:
     K1EA-CT  allocates 3 points for high band WPX   9Y4 contacts.
     1991 Radio Amateur Call Book says 9Y4 is "South America - Zone 9"

For the "North American" position:
      Encyclopedia indicated it was a country of  North America
      National Geographic Picture Atlas of Our World (1980) indicates 9Y4 is 
a North American country.

If 9Y4 is indeed in North America, it should be a  2 pointer (to/from W/VE) 
 since the rules state
"contacts between stations within the North American boundaries are worth 
two points
on 28,21 & 14 MHz."  The rules say nothing about zone 9 countries to be 
considered as
South America,  therefore the zone designation should not be a factor.

Can anyone explain this discrepancy? It would also be interesting to know 
how the 9Y4 logs
are calculated!

Wow.... hold on guys.....

I apologize for the bad grammar and the poor writing in the amp summary.  I 
did that on my coffee break, so I was pressed for time.  Please excuse the 
AL-82/AL-84 mixup.  Brain buffer dump!

Now then.  These are comments that I have received....not ones that I have 
made up.  No.  I am not bashing anyone's favorite amp.  Just reporting what 
people are telling me.

I thank you all for the stuff you have sent to me.  I am in the market for a 
new amp and the decision is really tough.

Some more comments that I have received:  ("INCOMING.....")

The most overwhelming comments were for the Alphas  Just about any model 
will do.  Operators who own one of these amps love them.  (When I started 
looking into amps, I was limiting myself to less that $2000, so Alphas were 
out of my price range.)

Ten Tec people are somewhat ticked off about my comments, but I was talking 
about the Centurion and not the Titan.  Some people have reported arcing in 
the Centurion while others have not.  MOst agree that Ten Tec has excellent 
repair and replacement service.  That has been their trade mark for years.  
The Titan is not in production any more, according to Ten Tec.  They had 
trouble selling enough to make it profitable.

Now, the Ameritrons are what is being sold out there in vast quantities.  
Why?  Don't know.  I received more comments about the Ameritrons than 
anything else.  People who own AL1200 like the amp very much except for the 
blower noise.  I have not found one person who didn't like the amp.  The 
AL-82 was favorable too, but the issue with that amp is it takes a lot of 
drive to get the full 1500 output.  The AL-1200 can be driven to 1500 watts 
with a 100 watt transceiver.  I tried to look up the cost of the 3A1200A7 
amp and AES has it selling for $665 as a replacement.  Some of the 
literature says it costs around $350, but I guess that has been several 
years ago.  (These are my comments)  That was an interesting fact! 

A lot of people are still in love with the SB-220 and the Drake L4B.

There are a large number of people who like to build amps.  They are pretty 
sure that building one is the only way to get what you want on a contest 
amp.  See the comments on the reflector.

Well, at least I started a whole new thread on the reflector.  

Best Regards to you all....

Lee, K0WA
