Heil mics and the K3

[AJSOENKE]

I hope this helps answer some of the questions about the K3 and support  for
mics.

First the Heil mics:

It will support the Elecraft  (Heil) Proset K2 and the Heil Proset HC-4 and
HC-5.

The HC-4 and  HC-5 are very similar, differing mainly in frequency response.
They are both  unamplified dynamic mics.
 
The ProSet K2 uses a similar mic element with a built in amp referred  to as
'IC'.  I don't know if the element is a HC-4 or HC-5 but its  very close in
response to the HC-5 judging from the audio I hear in my mon  signal.
 
They both have a mini phone plug (mono) for the mic that is colored grey.
 
The Heil Prosets have a standard (1/4") Stereo phone plug for the headset  
speakers. The stretched ot length between the mic and phone plugs just barely  
fits the mic to the rear panel and the phones to the front panel. I didn't like
 stretching them that much. A 1/4 female to 3.5mm male adapter would help and
 keep them both on the back for this Proset.
 
The Proset K2 has a mini stereo phone plug that easily allows for both  mic
and phone plugs in the rear panel. It also has a built in phasing  switch for
the phones.
 
Setup for the Proset K2 is default on the K3 rig as I received it. For the  
HC-5 I have, it required changes in the menu selects.  Refer to the Owner's  
manual 'MAIN Menu' Table on page 49 under the heading MIC SEL.
 
Tap MENU to get the MAIN menu, rotate VFO B knob to MIC SEL. Note  the
default setting on display
It may show 'rP.L bias' if it is default. This is the correct setting for  
the Proset K2 Headset.
 
To use a Proset HC-4/5 Headset, first rotate the VFO A dial to  rP.L bias or
fP.L bias  to select rear panel or front panel  connectors. Next,  tap the [2]
 (REV) button to turn off the  bias. The display will now indicate  'rF.L' or
'fP.L'.
 
Next tap the [1] (A/B) button to select the H/L for High mic gain/ Low  mic
gain.  For the Heil Proset HC-5 which I also use, the  settings will now
display 'rP.H' . Close the menu. Next set up a phone mode  (LSB/USB) and tap XMIT to
active no transmit TUNE, and speak into the mic so you  can adjust mic gain
level.  For me that is a setting of about 10. Adjust  the MON for a comfortable
level and set the mic gain for XMIT output that is  desired or CMP level you
like.
 
If you switch mics, be sure to reset the MIC SEL settings.
 
Aside from pin compatibilities on the 8 Pin connector this should work well  
with most any mic. That applies to PTT also.  IMHO, I would find it most  
effective to wire the mics to a mini phone plug or build a shore 8 Pin to phone  
plug adapter. I know many hand mics are plug compatible as is. Consult  the Mic
jack diagram on page 13 to confirm your mic.
 
Hope this is helpful.

Most helpful, thank you Alan.
I have a HM10-Dual I currently use and a Proset K2 on order - I was rather
expecting to connect the Proset to the front connector and the HM10 to the
rear - having bought the components etc to make an adapter cable to do that.
Guess I'll just do it the the other way.

Maybe I'm missing something (if so, someone please straighten me out) or
maybe some of this could be placed on the "add to software someday" list.

Front and Rear Mic Selection:

The "bias" settings for the Front and Rear mic inputs are independent. I can
set "bias" ON for Front and OFF for rear (or visa versa) and as I switch
from front to rear mic, the bias stays where I set it for the mic selected.

This does not seem to be true for the "H" and "L" parameter.  Set Front to
"H" and rear is automatically set to "H" - set rear to "L" and front is
automatically set to "L" - this parameter (Boost) does not currently seem to
be independent.

1.  Can this parameter setting be made to follow the selected mic input?

TX Equalizer:

Currently, when one sets the TX EQ for either the Front or Rear mic input,
that setting automatically applies to the other input.  So if you have very
different microphones you may not only have to switch the "Boost" (that's
what the built-in "help" banner calls "H" and "L") but you also have to
readjust EQ settings.

As an example, my K2 Proset requires very different EQ settings than my
Shure 444.  One is on the front and one is on the back.  It sure would be
nice to not have to readjust the EQ each time I switch mics.  BTW: the 444
works extremely well on the K3!

2.  Can the TX EQ setting be made to follow the selected mic input?

LOW Power Tuning:

Having to use the rotary Power Control to reduce power for the purpose of
initially tuning up an external manual tune amplifier and pressing the
"Tune" button is cumbersome - not to mention remembering to do it!

Some sort of scheme (menu item?) that allows one to select a "Tune" level
(set to the user's choice) would facilitate this.  Maybe something like -
Push and hold Tune for 2 seconds to apply 20 watts (or the users choice),
tap to exit - or - push and hold Tune for 2 seconds to apply 20 watts, then
push and hold again for full power (what ever you actually have the Power
control set to), tap to exit.  I'm sure someone creative can come up with
something better than this but you get the idea.

3.  Can a "low power tune" function be implemented?

Admittedly, these are "convenience" requests that simply would facilitate
what I do how I operate.  I'm guessing that there may be others that would
find these options of value.

What a great rig! Thanks!  73 es gud dxing -- Don N4HH K3 #83

I second all of these. I will be using 2 mcs too and I have an SGC I wish to
tune, I'd like to be able to set the 'low rf output for tune' level as well,
the SG-237 will tune on 3W.

If all is not lost, where is it?

I can tune my MFJ magnetic loop using 1W and reading the SWR off the
KAT2 in CAL S mode. But it's really annoying to do this and hear the
KAT2 start clicking away because I'd switched to the other antenna and
put the KAT2 on AUTO again and forgotten to switch it off when going
back to the loop.

If the KAT3 could be configured separately for the two antenna
sockets, that would be a big plus for me.

Julian - I had not gotten that far with my K3 but just checked it - and -
couldn't agree more!  Auto on Ant1 is Auto on Ant2, Bypass on Ant1 is Bypass
on Ant2 - these need to be independent.

That, along with a simple way to completely clear a CW memory ought to be
fairly easy to implement.
 
Over the years, I've really tried to keep my posts to the reflector and to
Eric at an absolute minimum - so - you won't see much from me in the
"public" arena.

I just discussed this with Wayne. It was an oversight and we will
definitely do this in an upcoming K3 f/w release.
