  Hi Brian,

I bought a Sark100 antenna analyzer, It uses a 50, a 150, and a 274 ohm 
resistors to calibrate it in 3 stages. I've got the 50 (48.9), (2 100's 
parallel) and the 150 (148.7), both at 5%, (Plus my meters margin of 
error, at .1 ohm shorted) I just need the 274. Not sure how close 
tolerance it's looking for. I guess I could try a 270 5% it can't hurt. 
Rat Shack has a card of 5 at 5% for a buck fitty. A bit more than forty 
cents but Rat Shack is all I've got for local parts. I guess there's 
nothing stopping me from bringing in my VOMit and testing in the store 
for the closest.

Thanks,
Randy, N3LRX
