so, have suitcase company on the way

One easy thing you can do to test your transformer is to put a 75 ohm
resistor on the proper side - and then use an SWR meter to measure the
impedance on the 50 ohm side. I like to also see how high in
frequency I can go before the SWR starts to rise. Most of the
transformers I wind typically work pretty well up to 7 or 10 MHz.
If you don't have an SWR meter - you can use your transmitter set for
a power level that won't burn up your resistor.

Thanks all for your wisdom . Some say not needed and some say to
use the 75 / 50 transformer . I figure it's easy enuf to do . So
now I'll try it and see for my self .
Thanks again, Ed N5DG

My receive antenna is 75 Ohm RG6 connected to my radio and I
want to wind a 2873000202 binocular core to step 75 to 50
Ohm's . I seen this info on W8JI web page but can't seem to
find it again.
I do remember it's 4 turns 50 Ohm and 5 turns 75 Ohm and all
wires come out the same side of the core . Am I correct so far?
Does it make a difference which winding I wind first ?
Thanks in advance , Ed N5DG
