Hi,
With the KY command - how big is the buffer in the K2? I know that I can send
up to 24 bytes per KY, can I send KY repeatedly to load up 100 characters?
While sending the KY buffer how to I stop sending and clear the buffer?
(Guess who's writing a new CW program?)

Thanks Gian. At this QTH, which is in the first hop zone of 40m BC signals
on their way to N.America, the receiver's IMD3DR needs to be 110 db approx
at 2 kHz spacing if used for weak signal SSB DXing above 7130 kHz. Of course
the LO must be very quiet. The big problem I have here is BC
I wrestled with this when I wrote my K2 remote control program and as
far as I can remember, no you can't. You can send 24 characters and
then you poll the K2 by sending KY; and test the reply back to find
out the buffer state. I think it sends 3 values, to say whether it is
empty, full, or able
TS870 has best RX audio I ever heard. This is often neglected area
in RX design, but stays in line from antenna to our brains.
My experience of many RX building is to keep amplifier naturally
linear without almost any feedback. Pass-band may be 20Hz30kHz.
I hope K3 has the same quality in
Sadly, the 870 was Kenwood's last real ham radio effort. And it came up
short with anyone who had another good rig to compare it to like the MP,
etc. Too bad Kenwood is now out of the high end rig game The other 2

I don't know anything about the 870, but most other

The ratings typically are 2.5 watts or less at 10% distortion,

does not

I can recommend the Almost All Digital Electronics L/C meter Model IIB,
available as kit at $99.95.

It can be built in a couple of hours and works a treat.

In most cases, I don't think you need to be more than
in the ballpark, at least when identifying parts.
My cheap meter reads 14 pico farads with nothing
hooked up, and has no null knob.
I just ADD 14 pico farads to the small values.
A 1 pico farad cap reads as 15
Inductance seems much
But it only does small values
I often need to measure caps to 100 mf, chokes to
50 henrys

I plan to put an external amplifier and speaker on my K3.
The K2 was designed with audio 'just strong enough' so that the the
receiver current drain would be low, and the K3 does not draw a huge
amount of receive current either - which tells me that there is not a
BIG audio amplifier in it
Brett,
You are absolutely correct - when identifying parts the meter does not
have to be accurate, a relative measurement will do fine. My point is
that one must realize the fact that all such DMM capacitance/inductance
measurements can be subject to these inaccuracies. Use what you have,
I'd order the second receiver in an instant if that option became a reality.

I have finished my K2 a couple of weeks ago and did not expect much from the

One can be wrong. The audio from the speaker is really excellent, at least
on CW.
I can't follow the remarks on low audio volume, because my unit has ample of
it.

Your experience substantiates my idea that everyone's ears and

When you listen to the music most people listen to, the quality

I would suggest that at some time or other, someone pressed the TUNE
