Re: [Elecraft] MC-60A

[Brian Denley]

That mic has a built in preamp, even though it is a dynamic mic.  You might 
consider that and lower your mic gain setting in the K3.

Re: [Elecraft] Radiosport MH-350ADJ with K2?

It’s a electret condenser mike element and requires bias 5.6-10k resister as

Re: [Elecraft] K4 S-meter characteristics

[Brian Denley]

The International Amateur Radio Union (IARU) Region 1 agreed on a technical 
recommendation for S Meter calibration for HF and VHF/UHF transceivers in 1981.

Why go back to 1947?

Re: [Elecraft] ALC implementation

[Brian Denley]

Wes:
Yes but I assume you have have used or use other xcvrs as well.  As a general 
comment, that doesn’t change the idea that using ALC to control a xcvr’s power 
to one’s linear isn’t the purpose of ALC and would seem to not be a very 
healthy practice.   If one were to choose that path, then one should be mindful 
that the result acts much like compression.  In some cases, lots of compression!

Nothing when that’s what you want.  But using ALC to control xcvr power is 
uncontrolled compression that may or may not be desired.

Re: [Elecraft] Elecraft / IC-7610 comparison

[Brian Denley]

Or are you saying that you connect the K4 to your in house router through 
Ethernet and then access it through WiFi?  (It’s making sense to me now! Hehe).

Thanks

[Elecraft] K2 battery

Well everything is installed and working very well.  Now my little K2 weighs 
more than my FT-950!   :o)

[Elecraft] ELECRAFT K2. Installing KBT2 with KIO2 in place

[Brian Denley]

Is the KBT2 going to fit ok with the KIO2 in the cover as well?  It seems like 
the battery is pinching the KIO2 coax cable pretty well.

Anyone else have both?

Thanks for that.  I never understood the Ameritron ALC instruction for my 
ALS-600 so I just never used the ALC.  That attached instruction was much 
clearer and made sense.

Re: [Elecraft] K2 with KPA-100

[Brian Denley]

..unless you build it in the ‘Twins’ configuration.  Then you have the KAT2 and 
KAT100 both available in the system along with the KPA100.  But you need 
another EC2 enclosure.

When I changed my 40 meter dipole from flat to inverted vee, I had to shorten

Any issues adding this option to a K2/100 set up in the ‘twins’ configuration?

Rod:
Correct.  Hc05 is Bluetooth 2.0.  The Hm10 is BLE.

Re: [Elecraft] K2 Build: Requesting Tips and Tricks

[Brian Denley]

Scott:
Get some magnification aid: binocular microscope, magnifying lamp, etc.  Some 
of those parts are pretty small and solder joints need to be inspected.  Good 
lighting is a must as well as an anti static mat.

Re: [Elecraft] K2 20 watt internal tuner

[Brian Denley]

Or you can use the ‘twins’ configuration of the K2/100:  with the KPA100 and 
the KAT100 in a separate EC2, you have a 100 watt rig with a 100 watt tuner.  
Unplug the K2 from the EC2 and you have a 20 watt QRP rig with a 20 watt tuner. 
 It’s that easy.

Re: [Elecraft] Receiver Similaritie"

[Brian Denley]

The HRO 500 was my dream receiver as a young guy but unaffordable for a 
teenager.  That one had a digital display and was all solid state.  Around 1967 
or so.  The old building that housed the National Radio plant is still there 
about a mile from where I live.

Re: [Elecraft] mic

[Brian Denley]

I agree on the Koss.  It cost me less than $40 and audio reports are all good.  
BTW, I also like my old Astatic 10DA on SSB.

I actually need the preamp with some mics, especially the dynamics  I don't

Re: [Elecraft] mic

[Brian Denley]

Agreed Jim but I haven't spent much money on any of the mic stuff and I also 
used a cheap ($40) headset rather frequently.  I do, however, prefer the 
dynamic mics.  The condensers that I have tried seem to pick up way too much 
background noise.

Re: [Elecraft] mic

[Brian Denley]

Clay:
What condenser capsule did you put in the 990 housing.  Just curious.  I am 
using the Behringer Shark DSP 110 as a preamp, low cut, and noise gate.  You 
can find them used for about $50.  Turn off phantom power with the dynamic mic. 
 I use the same setup with condensers - just turn on the phantom power.

Re: [Elecraft] mic

[Brian Denley]

Tried both condenser and dynamic.  I have settled on the dynamic (mxl bcd-1) as 
it picks up a lot less background sounds.  The condensers work very well but 
even pick up my wife talking the the dog downstairs!  I do use a noise gate and 
preamp.

Re: [Elecraft] Sync AM and checking VFO accuracy using WWV

[Brian Denley]

Fred, Don:
I ask because I am curious.  On any older receiver, calibration at 20 MHz would 
not guarantee cal below that ( or at any other frequency ).  One could be 5 hz 
high at 30 MHz but 10 hz low at 7 MHz.  Why is the K3 different?

Re: [Elecraft] KAt100 power on question

[Brian Denley]

Made the same mistake.  You need both power cables hooked up: one to the KAT100 
and one to the K2.  You can use a 'Y' cable to power both.

Re: [Elecraft] K2/100 and KAT2

[Brian Denley]

Ted:
You might look into building the K2/100 in the 'Twins' configuration.  To 
switch from 100 watts to qrp just requires disconnection the power amp box.  
This configuration allows the KAT2 to be used along with the high power tuner.  
I built mine that way and it works very well.

Re: [Elecraft] K3/K3S Pin 1 question

[Brian Denley]

I agree with Don as well here.  I use a Behringer Shark DSP110 which has both 
balanced XLR and 1/4 inch mono inputs and outputs that can be set to line or 
mic levels.  It also provides a noise gate and mic gain if you need it.  You 
can stay balanced as far as you want.   It was ~$50 used.

[Elecraft] K2/100 twins configuration

[Brian Denley]

How does the K2 get it's power when only the high current supply is connected?  
I ask because sometimes my K2 doesn't - unless I connect a supply to the K2 
directly.  Is it through the KIO2?
I also notice that when the power is lower the 11 watts, the SWR lights on my 
KAT100 do not light - but they do light when the power is 11 watts or higher.  
In both cases I can hear the KAT109 relays cranking away.

Thanks

Phil:
Yeah my audio reports are fine with the MH2 as well.  I'm not looking to widen

[Elecraft] Elecraft K2

[Brian Denley]

I am building a KAT100 and KPA100 in an separate EC2 housing.  There used to be 
some websites with details on this arrangement but I can no longer find them.  
As I understand things, the KPA100 / KAT100 will operate from the KIOS cable 
but do I need to disable my KAT2?

Thanks for any advice.

Re: [Elecraft] Way OT - The Metric System is Inevitable

[Brian Denley]

Engineering was metric (MKS) in the late 60s when I got my degree.  Sure we did 
some calculations with feet and inches by mostly it was meters, kilograms, etc.

Re: [Elecraft] Computers in the Stone Age

[Brian Denley]

No your history is not correct.  The apple II was available by at least '78 
using apple DOS.  A few years later MSDOS was created out of desperation by MS 
when IBM ( for the upcoming IBM PC) wouldn't buy their languages ( MS' only 
product) unless it came with an operating system, something MS didn't produce.  
Gates wad able to buy a barely legal clone of CP/M, the most popular op system 
at the time, and they produced it for IBM as PCDOS.  They then marketed it for 
themselves as MSDOS.
