Woo Hoo! 432 transverter for Christmas!!

[K6LMP]

I have a very loving and understanding XYL.  For Christmas, she gave me a 432 mHz Elecraft transverter kit.  I already have the internal 2 meter transverter in my K3, so this increases my available bands for VHF/UHF contests by 50% (from two to three).

Now I just have to get the kit assembled, aligned and field-tested before the January VHF-UHF Sweepstakes (Jan 21 weekend).  Shouldn't  be a problem, given the relative non-complexity of the kit.

One question for the group:  I don't own a UHF-capable noise generator. Is there an alternative means available to adjust alignment?

I'm getting sooo tired of having to tell other contesters that I only have 2 and 6 meters available! That's about to change.

Next up:  222 transverter!

How about the Trans World Traveler Antenna...

Has anyone been Very happy with them?

Has anyone been Very miserable with them?

Are they better than  a big KLM log  at 200 feet... yeah...right
I can dream.

Thanks

Thank you all...
Well I guess the laws of physics are still in full force.
There certainly are times  when I wish the rules could be bent...just a bit.
On the other hand... It's comforting to know that some things simply don't change.

So its the same old story... If yu want a big sig... Area, altitude and horsepower.

Let my ticket expire early in the last cycle... I'll get a new one in the spring. I'm looking for a Sugar Sugar Radio suffix ...

Yeah I really like that call AC7AC...

And speaking of room temp super conductors... There some guys up at the lab (Los Alamos) that are getting there.
My old, RIP Elmer W9JWI... Circa 1956 had set up in his shack a super cooled 2 meter antenna.... As the temp dropped he could shorten the elements and shill have the same swr's, watts out.

Sorry for the typos...it a bear typing with an iPad.

Convenience can be a very big issue in getting on the air or not in portable
operation. Yes, putting up a simple wire antenna can be inexpensive and
perform quite well if suitable supports are available. Yet there are many
times when a short vertical with a loading coil is attractive. One can build
such an antenna for sure, but for some its easier to let someone else build
them and buy them at a price much above the cost of the parts.
 
Do they work? Well, yes they do, more or less. Any antenna works better than
none. When conditions are good contacts can be made with even a poor antenna
 Its been shown that even a light bulb dummy load will work. Even at QRP
power levels contacts can be made. During the fox hunts I have heard
stations running 100 mW contacting the fox (using a good antenna I assume).
So with decent band conditions even an inefficient antenna will work at 5
watts or so to make some contacts.
 
Poor antennas sure will not give super results in all band conditions. Yet
one does not have to have the very best possible antenna before trying to
get on the air and making contacts. I think the best approach to making
contacts is just taking what ever you have for rig or antenna and get on the
air and see what you can work. Not just one CQ and giving up but gining it a
good try as time permits.

  My brother in Phoenix settled for a sequential call -  KD7DX.
  He's not about to ask for a "vanity" call!

This is a knock-off of an antenna offered by Force 12 a few years ago. I had
one. It worked okay. It is basically a vertical dipole with feed-point
lumped inductance that is tapped by switching a relay box. It is shortened,
so the t-bars provide added end capacitance. Unlike the BuddiPole, you don't
have to mess with the coil taps, manually. You can sit at the radio and turn
the rotary switch. But, it is not as portable as the BuddiPole, either. So,
I currently have a BuddiPole which I sometimes take with me and the K3/100
when I travel. I use the BuddiPole in conjunction with a small MFJ
transmatch. So, I use maybe two different tap postions on the coils for 10
through 40. Any losses due to high SWR at the feedpoint are more than
compensated for by the convenience of not having to play with those flimsy
tap gizmos.
