[Elecraft] K3 SWR Accuracy - reprise

[Geoffrey Downs]

But if you:

1. Connect the antenna directly to the K3, ANT1 say, with KAT3 in bypass and 
note the SWR reading on the K3,

2. Then disconnect the antenna from ANT 1 and instead connect the external 
SWR indicator to ANT 1 with a length of coax,

3. Then connect the antenna to the external SWR indicator,

should you not get a reading on the external indicator that you can properly 
compare with the one you noted in step 1?

If so, what do people find?

73 to all
