[Elecraft] Heil HC-5 Taiwanese Equivalent?

[Tony]

All:

I was looking an original Heil HC-5 microphone element for my KX3 when I 
came across this unit from an unknown manufacturer in Tawain:


See: 
https://www.electronicsurplus.com/qw442-1740-audio-microphones-element-only-miniature


There's no frequency response curve or other information other than a 
comment about the element favoring higher frequencies. I've emailed the 
seller to find out more.


I have an original HC-5 that produces excellent communications audio 
with my K3S and it would be nice to find one for the KX3. If anyone has 
an original HC-5 laying around, please let me know.


Tony

[Elecraft] FS: Hustler / Newtronics 5BTV Vertical Antenna + DX Eng. Tilt Plate

[James Bennett via Elecraft]

One of the last items to be sold in my goal to downsize before moving out of 
state: a modified Hustler / Newtronics 5BTV vertical antenna. It started out as 
an 80-40-20-15-10 meter version. However, when I put up my Inverted L several 
years ago there was interaction between the 5BTV and the “L” on 80 meters, so I 
removed the 80 meter parts from the vertical and added 30 meters instead, 
giving me 40-30-20-15-10 meter coverage. The antenna does need some TLC - using 
my VNA I can get it resonant on 40, 15, and 10 meters; 30 and 20 don’t 
cooperate and I don’t have the time to mess with it.

In addition to this vertical, I have the matching DX Engineering tilt over 
plate, model DXE-TB-3P.to go with it. This unit alone runs $62 plus tax at DXE.

I will let the vertical and the tilt plate go for $50. NO SHIPPING - you’ll 
need to pick up the antenna and tilt plate at my QTH in Folsom, CA - about 25 
miles east of Sacramento. The antenna is currently in use, mounted in my back 
yard. I will take it down and have it ready for the buyer to take away.

You can pay cash or PayPal. My PayPal address is w6...@mac.com 
 (I have not yet changed my PayPal address to coincide 
with my recent change of call to K7TXA)

Please contact me off-list if you are interested or have questions.

Thanks, Jim / K7TXA

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   My prediction of medium QSB came true.  I gave one report as S3 to 
S9 with a clear signal.  Noise was very light too.  But, both bands kept 
changing.  By the time I closed the first net everyone had disappeared.  
On forty meters I started off strong then got weaker as time passed.


   Those of us on the West Coast are thankful our antennas survived the 
recent storms.  Winds were high with a variety of flying objects ready 
to attack antennas.  Most of my antenna breaks are caused by snow 
bending the limbs of my fir trees until they pull the wire into parts.  
Even though I do not tie the legs of the antenna how the wire slides 
depends on the type of snowfall.  Luckily, this week had a foot of very 
dry snow instead of the normal slush.


   The glacier forming in Iowa is being thwarted one shovelful at a 
time.  Keep up the good work Roy :)  Mostly, reports were of staying 
inside, away from the nasty weather.  Propagation is good enough to keep 
people busy on many bands using a variety of modes.  I tested my new 
headphones on 75 meters, then I moved back to the CW portion where 
conversations are less medical.



  On 14050.8 kHz at 2200z:

W0CZ - Ken - ND

AB9V - Mike - IN

K6XK - Roy - IA

NO8V - John - MI


  On 7047.5 kHz at z:

W0CZ - Ken - ND

K6PJV - Dale - CA

K0DTJ - Brian - CA

W8OV - Dave - TX


   Until next week 73,

   Kevin.  KD5ONS

In the footsteps of Napoleon, the shadow figures stagger through the winter
Falling back before the gates of Moscow, standing in the wings like an 
avenger

And far away behind their lines, the partisans are stirring in the forest
Coming unexpectedly upon their outposts, growing like a promise
You'll never know, you'll never know, which way to turn, which way to 
look you'll never see us
As we steal into the blackness of the night you'll never know, you'll 
never hear us


And evening sings in a voice of amber, the dawn is surely coming
The morning road leads to Stalingrad, and the sky is softly humming

[Elecraft] P3 dynamic Ref Level ?

[John Oppenheimer]

Is there a P3 ability for Ref Lev settings for receive antenna versus
antenna 1? Trying to evaluate SNR difference between transmit and
receive antennas. Receive antenna has about 35dB lower gain than
transmit antenna. 80M band.

Re: [Elecraft] K3 synth / PLL faulty

[Victor Rosenthal]

The first thing to do when anything seems weird about the synths is to
check all of those little cables. Make they are all well-seated, and
push the connectors in and out a few times to clean off any corrosion.

I'm about to pull the rig apart but has anyone any advice before I 
do

that. Thanks in advance

This is the adapter that broke off in my Kenwood TS-830S. I had figured Sony = 
solid construction, but not quite so. It didn't take much tugging to snap it 
off. I had used it with other more modern 1/4" jacks with no problem. I think 
that it is a quality adapter for today, but I suspect that the Kenwood jack is 
simply stronger stuff. The internals of the Sony adapter are plastic, and 
simply snapped when I tried to remove the adapter. I then purchased a U-Green 
adapter...not sure if it will be the same, but I will likely insert it and 
leave it there. I still have my older headset with the 1/4" plug, but I prefer 
the newer Sony sets, and that way I can simply plug the 3.5 mm into the 
adapter. It occurred to me after I reassembled the Kenwood (disassembly to 
remove broken end) that there may be corrosion on the jack that causes 
sticking. I didn't note a loss of sound quality, but after all it's just 
limited bandwidth audio.
