[Fourlanders] W1GHZ transverter kit group buy

[Jim Worsham]

Sounds good Bob.  I am going to go ahead and order the stuff for at least
2304 and 3456.  The problem with 903 and 1296 is that if you make a Q with
W4NH on those bands it will not count for W4NH if you are also going to be a
W4NH operator.  I am not ready to give up my seat in front of the 6 meter
rig yet!  Then again if we just want to work each other on those 2 bands as
we rove around for the fun of it or you don't plan to be an operator at W4NH
then go for all 4 bands!  Remember that the deadline for placing the order
is 11/7 and you need to allow a few days for mailing.  I plan to place my
order as soon as I get back from my trip to K5ANDs get together next
weekend.  Now back to writing my project paper.

I have looked over the info on these kits, read the original W1GHZ 
articles and other comments.

I think they are a pretty good idea for getting into microwave stuff on 
the cheap.  As he mentions, they will need external filters if in a high 
RF environment and if they were to be used with amplifiers.

Altogether though they look like a good deal and a lot of fun to build. 
  You will need to supply some of the parts, especially the SMA 
connectors and pipe caps, but that's how he's keeping the prices down.

Paul and others who questioned the LO schemes were right on with their 
figuring.  Just subtract 144 (or add if high side injection and backward 
tuning) from the desired frequency and that gives you the LO frequency.
W1GHZ did a pretty neat trick to get these transverters together and use 
simple and no-tune components.

Anyway, I say go for it.  I am going to get a 3456 as I only have one of 
those and it's nice to be able to have two to talk to each other and 
make sure everything is working, which is more difficult with only one.

I also like his little relay board for RX/TX switching.  That will come 
in quite handy and I'll probably get several of those.

On the web site it did say that the parts kits DO NOT include the PCB so 
for each band you want, order the transverter parts kit, transverter 
board, appropriate LO parts kit, LO board and a relay kit.  Apparently 
the relay kit includes the board as it is not listed separately.

I'm looking forward to it too.  Enjoy!

Bob
