At the UT club station, N5XU, we have both TR Log and a K-3. You can put the
keying line from TR and the keying line from the K3 in parallel to your
rig by using a Y adaptor. I've never tried to connect the paddles to
both TR and the K-3 at the same time - I suppose you could use a three-conductor
Y adaptor for that, but I don't know if it would work out. The paddles are
plugged into the K-3 and moved to TR for a contest.
The advantages of having both for us are:
* Not everyone in the club does TR. Many go up there and never turn the
PC on - others just use the Windows PacketCluster client.
* We have the right button memory programmed to "599 TU" and the other five
buttons to the calls of our most active members.
* We have a couple of regular club station users who swear that the Super CMOS
Keyer III chipset is by far the best CW sending "feel" of anything driven
by iambic paddles.
The disadvantages of the K-3:
* The K-3 has no monitor volume control. The volume is really loud.
I don't think would necessarily be a hard mod.
* The K-3 has no on-off switch. It's really bizarre. I guess most people
use their rig's power supply.
* The K-3 does not implement a PTT line. While this isn't a problem for
our HF radio, we have a 2M IF rig for a 1296 MHz transmitter that needs a
PTT line to transmit CW at all. We use a Super CMOS Keyer III kit
(same chipset as the K-3, just purchased in kit form) that I added a
PTT circuit (thanks to KG5U) that isn't as good as having the chip
do PTT itself, but it does what we need. Having the keyer do PTT is
just a really good idea.
