I bought the BL2 PC board (E100253) and the switch (E640019) and removed the components from the BL1 and mounted them on the BL2 board. I now have a BL1 with switchable 4:1 or 1:1 operation.
Then I took my K2 out to our vacation house and set up my portable antenna - a 40 meter inverted vee fed with 300-ohm twinlead. It is up on a 28-foot pole and the feedline is about 50 feet long. I tried every band from 40m to 10m in both the 4:1 and 1:1 positions and noted the resulting SWR after the KAT2 found a match. My conclusion is that I will leave it in the 4:1 position for this antenna at this location. The BL2 has two cores and is rated for 250W. I felt that the BL1 power rating was more than sufficient for the K2 by itself. I use the BL2 at home with the QRO (100W to 150W) rigs and for that application I use the 1:1 position.. 72, John W2XS _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
