Hi,
I was tuning around on my K2 last evening and made an observation. While on
the 80 Meter band, I decided to keep tuning up in frequency until the PLL lost
lock, which didn't surprised me. What did surprise me was that when I kept
tuning...into the 40 meter band, the PLL didn't reaccquire

Ron forgot to mention that the only fix for the deaf on 80 is to spin the
VFO back down into band (or a reset - arrrgh).

Sounds like a good way to start, I'm starting with an

I could be wrong, but I suspect you could fix it by using direct
entry rather than spinning it back down.
best wishes,

No, that's not needed, at least not with current firmware (2.04).
Just do a direct frequency entry to put the rig back

I would not order one on the Internet until I had tried it first. Plus, the

Ron's inputs make reading the Reflector worth while.
Of course his technical comments are the real reason
we read his posts.
But I am so glad he gets OT with other comments.

As I recall, if you get the KPA100 it has an I/O so you do not need (and
I believe) can't install the I/O in the K2. They physically interfere
with each other.
I would also consider buying and installing the 160 meter adaptor before
the KPA100. Although I don't have the 160 adaptor in my

Re K2 875
I have a similar problem that Don, W3FPR had.
On page 61, Turning L30 has no effect on voltage measured at R30, when
frequency is at 4000 Khz. V is 8.35V.
But adjusting L30 on other bands adjusts voltage!
Checked L5: turns etc. C72, L30, OK.
Any idea?.

This is equally off of your request Tom but have you considered an
OptiVisor? (http://tinyurl.com/d5gwe)
I've suffered the swing-arm magnifiers like you, but I find an OptiVisor far
superior to even the best swing-arm magnifiers. I have used an OptiVisor

Tom,
I normally don't use magnification except for really small stuff and
examining boards, but my experience has not been good with the swing arm
magnifiers - if they are of sufficient power to do any good, I find I cannot
hold the soldering iron under them and work. Many OptiVisors suffer
Several people mentioned the issue of getting the right magnification with
an OptiVisor. I found mine in an Hobby store, so I was able to try them on.
You can vary the magnification without buying new lenses. Like most of us
over 40-something, I have presbyopia (old eyes) that won't focus up

I have used several Swing Arm Magnifier for about thirty years.
Like them very much. Built several Downeast Microwave SMT projects and

The mechanical sturdiness of some is less than desired. I found that the

around a hundred bucks for a decent one.
