Topband: K9AY Switching box

[Guy Olinger K2AV]

Gut suspicion is that you have a relay with fused contacts or blown
coil or some such, and your ACTUAL connections inside are not not what
you would be expecting from the schematic.  Or maybe a burned up trace
or something.

I have checked SWR at the base of the ant and it´s very reasonable, 1.2:1 and some 40 ohm. Measured inside the shack, and directly to MFJ-259, remains the same, but things change when i measure it through the switching relay box, SWR goes up 2.5:1..! I have leaved the coax connected directly to the rig, instead of connecting it to the relay box, but can switch loops anyway. Advantage of connecting it to relay box, is to get the Preamp working I guess...So, later today or tomorrow morning I will try how it works this way. What could be the reason of that increment in SWR when coax goes thru relay box..? Something has blown  inside..? Is there anyway to check the box..?
