Many scopes will indicate quite a bit above the bandwidth. They just will
not be usable for accurate measurement. The usual spec on the vertical
amplifier is, the scope will measure 3 db down at the specified bandwidth.
The rise time relates to bandwidth as BW/.35 for example a 100 MHz scope

I tried this several years ago. It worked for a while, but at times it went
into keyer mode. Don't remember exactly what I got, or why, but I couldn't

A few days ago someone was asking about a firmware change to make the K2

I just picked up a 1923 Vibroplex Original. I haven't used a bug in 40 years

The steps in Appendix F (Troubleshooting) of the manual that are listed

You are correct that only one correction factor for any one band is
available.

Rob,
It might be a problem with the alignment of the SSB filter, especially if
you choose to install the capacitors for the 2.6 kHz filter width. It could
also be a problem if you activate the RTTY filters - but the real answer
depends on your particular crystal set and the filter width you choos

As a quick test, don't adjust C22 or L30, just verify the tests on page

Putting a K1 on 160 can be done easily (see instructions below for one

The KAT1 will tune OK, but the range will not be as great as on higher

which is what. Note that the K1 will r
