Hello,

Please, please, does anybody remember the original poster's problem anymore?

Quote:

The results I got for 2:1 VSWR are as follows:-

               LP-100           K3
160         1.99                1.8
80           1.99                1.8
60           1.99                1.8
40           1.95                1.8
30           1.97                1.6
20           1.97                1.4
17           1.97                1.3
15           1.96                1.2
12           1.96                1.5
10           1.96                1.4  


I am repeating. This makes no sense given that he is using a parallel combination of two dummy loads which results in a 2:1 SWR. I am repeating: Either there is something wrong with the data or the K3 is faulty. Errors this large should not occur with properly functioning equipment.

The first statement is correct. Length of coax will transform impedance and
cause SWR meters to read differently.
