Fred,
It is a beta version so you will need to download from the P3 beta ftp site
ftp://ftp.elecraft.com/P3/firmware/beta/
Then browse in the P3 utility to where you downloaded the zip file
(p3m0105.zip). I have a directory to keep the firmware so I can locate them
easily.

If the scratches are not too deep you might try plastic polish, available at
most boat dealers and commonly used to polish windshields on boats and
airplanes.

Thanks to all at Elecraft
I was curious as to how you would implement the various requests!
The operation is intuitive and welcome.

I would not select a radio on the input impedance of the microphone input!
It is not critical at all - should be at least 10 times the microphone
impedance.
Pro-Audio from as far back as the antique Western Electric unbalanced
systems of the 40s tend to be in the range of 1 k to 10 k.
About mid-2010, when I went from an XP machine to a W7-64bit, I just plugged
in my Prolific USB to RS232 adaptor. W7 then loaded its drivers and off it
went in a matter of seconds.
My SignaLink (USB sound card) worked just as easily.
Both fully interfaced my K3 with the computer with no hassles.
Thanks to everyone at Elecraft and all the helpers on the Elecraft list.
Merry Christmas and and a Prosperous New Year to all.

Thanks for my K3 and by extension the manual both in paper and pdf.
I may be in the minority - this is my second radio with only about 6 months
experience before purchasing the K3. The manual was instrumental in getting

The K3 can power the P3 directly from its switched power output connector

If you already are powering other devices make sure you do not exceed the
maximum output of 0.5 amps.

that I bought from broadcast equipment suppliers. Broadcast equipment

The machine will expect synchronizing pulses to lock up the head and capstan
motors. Without sync some machines will not even go into the record mode, if
it does noise will really confuse the motor servos.
The pass band of a video recorder for NTSC (analog) is not necessarily flat

Another little known fact is BNCs come in both 50 ohm 75 ohm versions.
I used both 75 ohm (video) 50 ohm (RF) at work.
So verify if it matters to the usage!

If you aren't married to the original element you could change it out to an
electret element wired directly to the K3 input with the bias turned on. I

The electret element is available from many sources (including your local

I am using the 1/10/08 schematics - it shows a fuse (F2 - 0.6A) for the aux

Broadcast transmitters delivered from RCA GE up to at least 1968 had PCBs

In broadcast pro-audio (probably other services) - microphones aren't

better.
