Re: [Elecraft] Not Elecraft - PA3AKE High Pergormance Front End Upgrade

Thanks Gian. It might be of interest to people in Europe who homebrew as 
well as buy rigs that contrary to popular wisdom and based on 'on air' use, 
the high IMDDR3 at 1 kHz spacing of Martein's front end and roofing filter 
is worth having when working SSB DX zero beat with or among the 40m BC 
stations. To date AM BC transmitter phase noise does not appear to be a 
limiting factor, their modulation can be sometimes.

I know me well enough.  There is absolutely no possible way I'll leave
it just sitting there unopened.  If I were to try to just ignore it and
work on my photo class, I'd end up sitting there in a zombie daze,
unable to concentrate on the Flash Exposure Lesson I need to prepare.

If the K3 arrives, I'll have the box opened between the time I arrive

 7050.3 . I left the rig sitting for a while and when I came back to it, the

 Thank you

If you got the rig without a manual, they can be downloaded from
Elecraft's website.  It's an invaluable tool to have.  Lots of
troubleshooting guide included, to help you decide what errors like
E42 mean.  Nice schematics too.

Re: Re: [Elecraft] K3 wih - PA3AKE High Pergormance Front End

2008-04-14 Thread Geoffrey Mackenzie-Kennedy

David,

May I get back to you later this evening off-list with some thoughts about 
this approach. An advantage gained by using a variable IF is that the 
close-in phase noise of the first mixer's fixed frequency LO injection can 
be very low indeed, but there are other disadvantages.


The gain of Martein's front end between the antenna port and roofing filter 
input is negative, about -7 db depending on the band in use, since neither a 
post mixer amp nor a preamp is used neither of which is desireable nor 
necessary. This means that the IF's noise figure has to be low in the region 
of 2 db.  Also the Input IP3 of the IF has to be +50dbm, or better if at all 
possible, to take full advantage of this front end's performance.

No, scanning is deliberately disabled on 6 meters. There is an issue 
with FCC approval. As I understand it (someone will correct me if I'm 
wrong), a manufacturer of equipment capable of scanning above 30 mHz 
must prove that it can't scan the 800 or 900 mHz region used by analog 
cellular phones (if there are any!). When Elecraft comes up for air they 
will do this and then enable scanning on 6 meters.

Sounds like me but I have just ordered mine.  I have read most of everything
I could download (two full loose-leaf notebooks), still have a bit to go.
But I have LONG time to wait (ordered 3/30).  I had a K2, REALLY impressed
by the receive but the radio just didn't work out (I'll leave it at that).
Read all the download stuff on the K2 and then when I made the decision, I
started reading the K3 stuff and ordered it mainly on the performance of the
K2 receive.  This wait will be the slowest time of my life.

I will have to reread the books when it gets closer to my ship date as I
will have forgotten everything by then.

Re: [Elecraft] Buddipoles and KX1

2008-04-14 Thread Tom AK2B

Hi Tom,

The Buddipole is a great product with Elecraft-like support. I have both the
Buddipole and the KX-1 and as a portable system, it works fine. 
Since you are going to be a newly minted ham, I would not recommend a
Buddipole right now. I would take the suggestion of the others and build a
44 or 66 foot doublet and feed it with twin lead or build a resonant dipole.
Any of these simple antennas will out perform a Buddipole and will give you
some basic antenna knowledge. Using QRP can be very frustrating for a new
ham and with the poor band conditions you will need all the help you can
get.

So much for the practical! If you are hell-bent on a Buddipole or portable
use is all you intend to do then order it with a four or five section
shock-corded whip. I find those telescoping whips too easy to bend or break
and the dipole arrangement almost useless unless you have loads of time to
put up a taller guyed mast. I use it only as a vertical. In the park I
usually just bungi the mast section to a fence post for support and use one
elevated radial. Above the mast section go an extension arm, the coil,
another extension arm and then the shock–corded whip. I then connect the
antenna to the KX-1 and run the shorting wire up and down the loading coil
for the best signal. That’s it. It takes just a few minutes to set up. In
the car I drive down by the Atlantic Ocean (oceans are your DX friend),
attach the same arrangement to a ball mount, leave out the radial and I’m on
the air. To me, the time taken for setup and teardown is very important
since it promotes spontaneity and on many occasions, like a lunch break,
time is important.

Tom, AK2B

[Elecraft] AGC hang after transmitting

2008-04-14 Thread ab2tc

Hi all,

There has been a lot of posts lately of an apparent problem with the TX mic
gain being low initially or after a recorded message finishes. I have never
noticed this, but I have the exact opposite problem. Occasionally when
ending an SSB transmission, the RX initially has reduced gain and I can see
the S-meter decaying as the receiver recovers. It doesn't happen every time.
I am not sure whether there was always a strong signal in the receiver
immediately prior to transmitting when this happens. Anybody else
experiencing this?

 Lennart,
 
 If you have transmit power problems in CW mode or TUNE, then the only 
 part of the SSB opyion board that could cause that condition is Q1, Q2, 
 Q3 and the associated components.
 
 Look at the KSB2 board schematic near the bottom and you will see which 
 components need to be checked.
 
 

So I check on the schematic and there is a lot of RP3 there... When I took
the resistor RP5 and read 473 my brain must have locked up and I put the
473 resistor as RP3, Should have been at RP5. When I swapped RP3 and RP5
things were going a lot better :-) So it was indeed a component in that
area, a very stupid component to make a mistake on. Those resistor networks
does not exactly fall out by themselves once soldered. One hour later the
board is in place and gives perfectly normal response now.

Thanks for telling me what components to look for mistakes on, saved me a
lot of time.

[Elecraft] troubleshooting the KNB2

2008-04-14 Thread Brian Lloyd

Sorry to have been away for so long. I've been busy.

My students (5th-8th grade) and I have finished the K2, finished the  
KNB2, almost finished the KSB2 (I hope we will have that done today),  
and haven't started on the KPA100 yet. K2 works great. Lovely receiver!


But, it appears that the KNB2 is doing nothing. Our school sits  
practically under a 240KV power line. We have constant pulse-type  
power line noise that kicks the noise floor up about 6dB-8dB on  
80M-30M. The NB on our IC-706MkII takes it right out. The KNB2 appears  
to do nothing.


For testing I have been using my heat-gun's electric motor as a noise  
source. Noise is plainly audible. NB appears to have no effect.


What I have determined:

1. 6V good (5.98V);
2. diode are good (conduct in proper direction) and installed correctly;
3. threshold line switches properly;
4. Pulse width line switches properly;
5. blanker on/off line switches properly;
6. 6NB switches properly;
7. U1 is showing good gain between input (pin 4) and output (pin 8);
8. No blanking pulse on GATE.

Since the receiver works with the KNB2 installed, that implies that  
the BPF is OK. Gain at U1 implies U1 is OK. All the control lines  
switch which implies that U3 is OK.


Visual inspection shows no improper component placement. Diodes,  
transistors, and ICs are oriented correctly.


I have an HP 180A analog scope. I see signal (how I determined U1 has  
gain) but haven't had success getting it to trigger on the noise pulses.


So, anyone have any suggestions for further trouble shooting?

[Elecraft] re signal level of I F output on K3

2008-04-14 Thread Fern Rivard
What is the level output of the I F output on the K3? I'm trying to use the 
Kenwood SM-220 panadaptor with mine but can't get enough output from the I F of 
the K3. I've got on loan an I F amp @ 8.215 mhz set at 15 db gain  from Jack of 
Clifton Laboratories to try and cure the problem but even with the amp I need a 
minimum of 200 microvolts signal input to the antenna jack of the K3 before I 
can even detect it on the SM-220 panadaptor  I F input even with the  15 db 
amplifier. Looking at the schematic of the K3, there should be approximately 
the same level coming out of the 8.215 khz I F as what the received signal is. 
The manual for the K3 does NOT give any information on this. Any help would be 
greatly appreciated.
Thanks from Fern   VE7GZ

The originator of the famous NBS design (W0PW) is a

loop away and a trimmer to the input, so you will be able to keep mic  
preamp setting used in SSB mode. When using RTTY mode with the K2, it  
already bypass SSB compressor setting. So that way, you can now  
virutally connect anything to the DATA port TNC, NUE-PSK modem,  
computer sound card. It will act like the DATA port of a Yaesu  
FT-817 familly.


I also add another connector for futur project. an external VFO  
dial with keypad.


Stay tuned !!!

Best 73

[Elecraft] K3 received at WA7U QTH 04-14-2008

2008-04-14 Thread Todd J Gahagan
Got my K3 by USPS priority at noon today. Ordered 10-22-2007, shipped 
04-11-2008.   Just about to start calibration of the synthesizer.  Took about 6 
hours to get to this point.  This radio is a great pleasure to build as was the 
K2 and I'm sure even more fun to operate.  My thanks to Elecraft for such a 
great radio.

Todd, WA7U

[Elecraft] OT-Noalox grease

2008-04-14 Thread Charles Harpole

As reported to me by W4YOK via a letter from the mfg, Ideal, who makes Noalox, 
the product that is used

to mate dis-similar metals, is not actually a conductor.  It does have vy small 
particles of metal in the 

grease but those can not really be counted on the conduct, sez mfg.  Instead, 
it is made to retard

water and to strip oxidation automatically off aluminum.  Maybe that is why 
it works so well on

the joints of yagis telescopic or swaged elements.  I have used this kind of 
product for years on

antennas and --taken apart years later-- the stuff makes disassembly a snap.   
73,

RE: [Elecraft] AGC hang after transmitting

2008-04-14 Thread Joe Subich, W4TV

Knut, 

The problem has nothing to do with the receiver.  The problem 
occurs when the mic input is overdriven and the microphone AGC 
reduces the gain in the transmit audio path.  

Lyle is working on the problem.

 Subject: [Elecraft] AGC hang after transmitting
 
 
 
 Hi all,
 
 There has been a lot of posts lately of an apparent problem 
 with the TX mic gain being low initially or after a recorded 
 message finishes. I have never noticed this, but I have the 
 exact opposite problem. Occasionally when ending an SSB 
 transmission, the RX initially has reduced gain and I can see 
 the S-meter decaying as the receiver recovers. It doesn't 
 happen every time. I am not sure whether there was always a 
 strong signal in the receiver immediately prior to 
 transmitting when this happens. Anybody else experiencing this?

RE: [Elecraft] Microphones for K3?

2008-04-14 Thread Joe Subich, W4TV


I have a factory kenwood mic mc-43,

Yes (I'm using one)

   a MC-60A 

Maybe.  It will work if you leave the preamplifier off or use batteries.

Otherwise the connection on pin 5 of the mic plug (rig) will need to be 
moved to pin 6. 

 a Heil Pro set all for my TS-850S; 

Yes, if it is the HC-4 or HC-5 version and you are using the Heil AD-1K 
adapter (or you connect it to the rear panel mic input).  I'm also using

a ProSet with HC-5. 

73,

 Guys,
 
I have a factory kenwood mic mc-43, a MC-60A and
 a Heil Pro set all for my TS-850S; will these work
 without a rewire? Also who has bought the TXCO what
 difference does it make?
 
 Thanks and 73m
