[Elecraft] XVTR Out level

[w4sc]

At 15MHz you are starting to be out of the 20M passband filter, at 16MHz you are well out of the 20M pass band,,, the passband on 10M is around 2 or 3MHz wide and thus would provide the proper drive level for  144 (28MHz), 145 (29MHz), and 146 (30MHz) MHz operation.

 From the K3 users manual, pp71:

Band-Pass Filters (BPFs)
At back-left is the bank of ham-band BPFs. These filters are just wide enough to cover each ham band, so they provide good rejection of IMD products during both transmit and receive. Hi-Q components, including large toroids, ensure low loss and high signal-handling capability.
