Re: [Elecraft] Want to buy: Elecraft XG1 or XG2

[Ted Cowan]

Thanks everyone for your amazing response to my request.  This is the first
time I have ever posted a want-to-buy, so please forgive me for not
following up.

I have an XG2 on its way to me and it should arrive by Tuesday evening.  I
will test it out right away and report here if I am satisfied with my
purchase or if I need to reach out to you again.  Those of you wanting to
sell yours to others are of course free to do so.

It was the first iteration of the XG2. It was only one band as opposed
to 3 on the XG2. It went out of production after the XG2 release.

I only know because I was asked to produce an enclosure for an XG1 and
like you, never heard of it until that point.

Of course! I see it's like an XG-2 but only has 40M output instead of three 
bands.

[Elecraft] XG1 and K2 question

[Eddy]

Hello K2 receiver wizards, what makes more sense when using the XG1 to set the 
S-meter on a K2, pre-amp on or off? As you well know, pre-amp makes a big 
difference on 40mtr..I suppose most K2 owners turn pre-amp on from 20mtrs 
and up, while turning it off 160-40 for better selectivity.

Many thanks for your advice and opinions.

Re: [Elecraft] XG1 and K2 question

[Dale Putnam]

Hi Ed,  I calibrate the S meter with the preamp off... that allows the gain of 
the preamp to be measured and evaluated also.And gives a standard of S 9.And, 
with my two K2s, I seldom use the preamp on any band, until conditions allow, I 
find plenty of gain, that overpowers the filters with the preamp and amped 
noise. However, I did, before I realigned one of them, notice that I was using 
the preamp quite often as the band noise was low... and.. when measured, so was 
the sensitivity. Realigned... no problem and I have gotten verysettled with 
the low noise from the rx on a quite band... the preamp, many times will add 
enough noise to make it sound like the band is alive... when if fact.. the band 
is alive.. but with signals and not so much noise.
Have a great day,

Re: [Elecraft] XG1 and K2 question

[EricJ]

The calibration is a pseudo-standard or convention, i.e 50 uV at the 
antenna input equals S9 on the meter. So it doesn't make much sense to 
have the preamp on for the measurement. If you did, the only way to 
compare two rigs would be to specify whether the preamp is on or off on 
each rig. Not that the convention is a valid comparison of two rigs.


But it's just a convention so you do what's meaningful for you.

Re: [Elecraft] XG1 and K2 question

[Don Wilhelm]

Ed,

You will have to make up your own mind on that question.
If you normally use the bands that usually have the preamp on, you would 
probably want to set it with the preamp on.


However if most of your activity is on bands where you do not run the 
preamp, set it with the preamp off.


Keep in mind that the S-meter display can be a relative indication 
rather than an absolute.  The K2 does a lot better than many other 
transceivers in that the s-meter calibration can be set according to 
your desires or to some 'standard' such as the normally accepted -73 dBm 
(50 uV) indicating S-9.


If you choose to calibrate with the preamp on, just add 2 S-units to the 
reading, or if above S-9, add 10 dB when giving reports with the preamp 
off.  Conversely, subtract 2 S-units or 10 dB when operating with the 
preamp on if you calibrated it with the preamp off.


Some folks like to see a lively S-meter in all cases, and if you are 
one of those, set it with the preamp off.
Isn't everyone S-9 unless you are running QRP and then it is S-5 :-) .  
I have heard very few really honest reports in my days.

[Elecraft] XG1

[Mike Harris]

G'day,

A cautionary tale.

I decided to check the total receive signal loss through my system
from the coax termination in the wall to the K3, via the amp and
antenna switching having had a hot switching event.

I first plugged the XG1 directly into the K3 and with the agc off
set the dBV reading to 0.0 with 50uV.  Next moved the XG1 right to
the end of the last internal coax cable.  -1.7dBV!

Whilst moving the XG1 I noticed that the reading returned to the set
point 0.0 dBV when I picked it up.

I turned out that placing the XG1 on its rubber feet on a metallic
surface (the case of the linear) resulted in this signal loss.
Holding the XG1 in the air by the cable that connected it to the K3
removed this loss.  I didn't check the effect of placing it on the
wooden desk surface.

When connected to the K3 I simply use a BNC to PL259 adapter and it
sticks out the back self supported.

Just an observation.

Regards,

Mike VP8NO

Re: [Elecraft] XG1 or XG2 on 10M?

[N2TK, Tony]

Hi Don,
Tnx for the info. In the past I used the wattmeter, dummy load setup. And it
does the job quite well. It is just a pain to do by yourself and requires a
number of trips back and forth between the shack and the tower out back to
check out 7 coax/hardline runs. I only tilt over the tower every few years
(I'm rebuilding the MonstIR and adding 60/80M to it). The last time was 4
years ago. When I do that I like to check out everything. I keep a log on
everything including measured coax loss in case a problem occurs.   

I had bought a fundamental 10M crystal but could not get it to oscillate
with the XG1. But I had not played much with changing capacitor values.

I plan on using a signal generator and low level power meter this weekend.

But a 10M XG2 makes it easier to do. 20M is too low in frequency to really
indicate loss on 10M. 

By the way I had installed a 160M crystal in one of my XG1's. Stick a wire
in it and it becomes a nice signal source for checking low band receive
antennas.

Tony,

The XG1 and XG2 require a fundamental mode crystal.  Reliable 
fundamental mode crystals for 10 meters are difficult to find.

For what you want to accomplish, I would suggest an alternative.  Put a 
dummy load at the antenna end of the coax.  Use a wattmeter at the shack 
end, and transmit at some known (and controlled) level - then put the 
wattmeter at the dummy load end and transmit with the same level.
The power difference will allow you to calculate the loss.

If you have a signal generator like the HP8640 and a low level power 
meter, you can use that instead of the transmitter and high level wattmeter.

There are many other ways to skin that cat.

[Elecraft] XG1

[N2TK]

 I have both the XG1 and the XG2. What I would like  is to convert the XG1
 to either 160 or 10M. If  this is possible I would buy another XG1. Can
 anyone suggest any ideas on this and if it doable and component values?
 
 The reason I want both 160M and 10M:
 For 160M I could use the  XG1 to test and check receive loops. The XG1
 could be a signal source connected to a loop. I presently use an MFJ
 antenna analyzer for this.
 
 For 10M I could use the XG1 to test coax loss. I keep a record of all my
 coax loss going to the tower and the other antennas. Instead of dragging
 out the dummy load I could use the XG1 as a signal source on the end of
 the coax and check on the receiver in the shack for approximate loss.

[Elecraft] XG1 Verification of Output Level

[Gordon Lois Duff]

I have had an XG1 for some time now.  I think it originally showed -72 dBm
on my Flex SDR1000.  

 

Now I see about -68 dBm on the SDR1000 and -60 dBm on my QS1R.  

 

How can I verify that the XG1 is operating correctly?  I have measured the
voltage at C3/R3 and it is 1.22 volts (and the battery is 2.99 volts). 

 

Once I have verified the XG1 output I will look into the receiver
performance.

[Elecraft] XG1 freq. adjustment

[Greg Derda]

I've just built an XG1, and it is not clear to me how to adjust the 
frequency using C6.  According to the manual:


the frequency of the XG1 can set to exactly 7040.00 by adjusting C6 
with an insulated tuning tool.  Otherwise leave C6 set at its 
midpoint.


With C6 centered, there is a definite tone at 7040.00, but the 
bandwidth of the tone is fairly wide, and it is higher pitched, and a 
good s-bar louder up around 7060.00.  Should I trim C6 to bring what 
appears to be the loudest peak down to 7040 (this doesn't seem very 
precise)?  Maybe I've goofed up and there shouldn't be any bandwidth to 
the tone (i.e., maybe is is supposed to be a precise tone)?


Any suggestions on how to calibrate the XG1 would be greatly 
appreciated!


Thanks,
Greg, ki4mmm

Vin,

The narrow end of the blue bodied trimmer on my XG1 is near the label for
C6.
In general, follow the instructions rather than the diagrams - I believe
this trimmer was changed sometime in the life of the XG1, and the older
white bodied trimmer may have best been placed the other way around.

[Elecraft] XG1 Results with K1 s/n 1018

[Clark Macaulay]

Hello everyone!  My first post to this august group.
   
  I've always suspected my K1 receiver to be a little weak because of very weak 
audio fro the speaker although headphone volume is fine.  Not knowing whether 
it was an audio or RF problem, an XG1 was ordered and here are the results @ 
7040Khz using the 1 microV setting and measuring the AC voltage at the speaker 
terminals per XG1 instructions:
   
  --XG1 ON: 104 mV
  --XG1 OFF: 12 mV
   
  Using the formula in the XG1 instructions:
  --R(atio) = 8.2
  --  Log R = .9
  -- 20 x Log R = 18 db
  -- MDS approximates -107- 18 = -125 dbm
   
  which is a little off the -130 dbm identified in the XG1 instructions.
   
  My questions are:
   
  1) Are my results within range of what should be expected? When an antenna is 
attached, the noise rises significantly indicating to me that the receiver is 
working, but that is hardly an objective measurement.
   
  2) Should I stop trying to figure out why the speaker volume is so and low 
and just use headphones?  When I touch pin 1 of mixer U2, I get a loud blast 
from the speaker, so I'm convinced the audio chain is fine.  I'm just not sure 
if the RF level into it is high enough.  I have the K1-4 filter board and am 
sure I've peaked it for best results.
   
  BTW:  I do have the internal battery option, so when I say speaker volume is 
very low, I'm referring to the speaker and top cover being in place.

RE: [Elecraft] XG1 Results with K1 s/n 1018

[Ron D'Eau Claire]

Hi, Clark:

It sounds like you are dealing with two different issues: Minimum
Discernable Signal (MDS) measurement and raw audio power. 

The MDS that you are measuring with the XG1 should not be associated with
how much racket you get in the speaker or phones. A very poor receiver can
make a lot of noise! It all depends upon the amount of amplification the
receiver has, which is quite different from the sensitivity. 

First, are you using a bandwidth of 500 Hz for the MDS measurement using the
XG1? The MDS you get will depend a lot upon that bandwidth. Since you are
measuring the receiver's response to an unmodulated signal and comparing it
to the noise with no signal, the narrower the bandwidth, the less noise
energy you will detect with the XG1 turned off, so the better the calculated
MDS. CW receiver MDS is commonly calculated using a receiver bandwidth of
500 Hz so we're comparing apples and apples when comparing two rigs. 

All that aside, the audio level is a wholly different problem. I do not own
a K1 so I'll leave it to K1 owners to suggest remedies for that.

Re: [Elecraft] XG1 Report

[g4ilo]

Isn't that simply because most transceivers derive the S-meter reading from 
the AGC level, and you don't want the AGC acting on weak, but still 
readable signals?

Reports based on the actual S-meter reading are completely meaningless, due 
to the lack of standardisation and the fact that whether the preamp or 
attenuator are used affects the reading.

[Elecraft] XG1 Report

[Earl W Cunningham]

I picked up an XG1 oscillator kit at the Elecraft booth at the DX
convention in Visalia.  Assembled it this morning and used it's 50 uV
setting to check the S-meters in my four HF radios with the following
results:

Elecraft K2/100 = S9 (digital S-meter) (S-meter was calibrated by
adjusting the value of R1 for best AGC action and using the S-meter
calibration procedure described in the manual, i.e., full scale = RF gain
fully CCW and S0 = RF gain fully CW with antenna disconnected --
apparently done this way, there is no need to calibrate S9 on the meter
using the method described by others on this e-mail reflector).

Yaesu FT-1000MP = S9 (main and sub rx's, digital S-meters)

Icom IC-756Pro3 = S9+3 dB (analog S-meter), S9 (digital S-meter)

Kenwood TS-830S = S9+3 dB (analog S-meter) (1 uV setting = S4)

Years ago I calibrated the S-meter in the TS-830S using a metrology lab
calibrated HP-610C signal generator.  I surmise that the Icom's S-meter
was factory calibrated at S9 using 50 uV.  I therefore believe the -73
dBm output of the my XG1 is actually -70 dBm (70.7 uV).

If the 50 uV setting on the XG1 is actually -70 dBm, then the 1 uV
setting should be down another 34 dB, or -104 dBm (1.414 uV).

Interestingly, only the Kenwood has an accurate S-meter for signal levels
below S9.  It's S-meter reading with the XG1 set for 1 uV was S4 (all
other radios were S0).  Based on the 6 dB standard that each S-unit = 6
dB (and -73 dBm = S9) means that S4 is a signal level of -103 dBm, which
agrees quite closely with the presumed -104 dBm output of the XG1 at the
1 uV setting.

When I get ambitious, I'll perform the procedure for determining the
noise floor of each receiver as described in the XG1 manual.

All in all, the XG-1 is a neat piece of test equipment to add to the
shack and, as the saying goes, Good enough for government work.

Or, you could surmise that the K2, FT100 MP main, FT100MP sub, and Icom 
digital are accurate, the Icom analog is 3 dB high and that the Kenwood 
has drifted 3 dB since the cal was done so long ago...


Or, that the XG-1 is 1.5 dB high and all the radios are +/- 1.5 dB of 
that :-)

Someone I was chatting with recently said he had tested the S-meters of
several receivers and found that 1 S-unit can equal anything from 3 dB to
more than 6 dB. I had always assumed the target was 6 dB/S-unit. Apparently
not so.

==

Years ago, there were two standards for S-meters.

1) The Collins standard was 100 uV = S9 and each S-unit was 8 dB.

2) The Hallicrafters standard was 50 uV = S9 and each S-unit was 6 dB.

Manufacturers naturally adopted the Hallicrafters standard because the
Collins standard resulted in a stingier S-meter (higher S-meter readings
= better receiver, right? - No)

It is rare, with the new transceivers currently on the market to find one
that strictly adheres to the standard.  Virtually every tranceiver
today uses the 50 uV = S9 criterion, but the change per S-unit is much
less than 6 dB.  This results in a substantial signal such as 1 uV (which
should read S3.5 on an accurate S-meter).not even budging the S-meter on
most receivers today.

In dB above S9, the S-meters most transceivers today seem to be fairly
accurate.

If all manufacturers complied with the standard to the letter, S-meter
readings would be more meaningful.  As it is now, they are useful only
for reference readings such as when someone does an A/B check on his
antennas with you.

BTW, the values I posted originally were with the receiver preamp turned
off in all cases.

RE: [Elecraft] XG1 battery voltage(s) reference needed

Rick,
You must have a circuit problem, either there is a bad component, or a 
component in the wrong place, a bad solder joint or something in the oscillator 
is drawing too much current.
Check U2 for 1.22 volts.  Make sure R9 is correct value.  Check voltage at the 
junction of R10 and R11 should be close to 1.5 volts for a good battery.

RE: [Elecraft] XG1 battery voltage(s) reference needed

Allen,

I believe that you are correct and figured that my XG1 had too much current
draw.  I will do that as soon as I have the chance.  Right now am just a bit
busy getting a couple of computers built up to replace some boxes that
recently went belly up.  In a couple of weeks I'll be recuperating from some
surgery and plan on having my K2 and some other stuff upstairs with me to
keep me entertained.  Will do the checking then.

73s  thanks,

Could someone with an XG1 please measure the battery voltage with the board

I have tried three batteries in mine and the yellow light always comes on.
My batteries were anywhere from 3.05 to 3.15 no load, but dropped to 2.9 or

RE: [Elecraft] XG1... other frequencies possible?

[W3FPR - Don Wilhelm]

Happy Easter to everyone from here too.

Joe,

I would think you could just plug in another fundamental crystal and try it.
Do be aware that it may alter the output level from its normal 1 uV and 50
uV, so do test the levels before relying on any particular output - the
output should be consistent, just not necessarily at 1 or 50 microvolts.

73,

Hi Joe,

The XG1 has quite strong output on its harmonics, 14.080, 21.120 and
28.160MHz. Information is on page 3 of the manual. The second harmonic on
14.080 is approximately 7dB down on the fundamental.

RE: [Elecraft] XG1... other frequencies possible?

[EricJ]

 That's fine for K2 builders, but it wasn't much help with a K1 since they
don't tune that high on 20 and 15 with the optional 80 kc band spread. I
stuck a 14.060 mc crystal I had left over from converting a Rock-Mite 20 to
15m and it worked fine, though I didn't measure the output to see how much
it deviated from the 50 uV 40m output. It's bound to be different.

I used a trick I first learned from Chuck, W5USJ, of using two Augat
machined socket pins taken from an IC socket. Pull out the crystal, solder
two of these pins in and plug in the crystal. Now you can stick anything you
have into it. I got the pins from a new CPU socket for some early Pentium
chip that I bought at a surplus store for 50 cents. With a firm grip on the
bottom of a pin with needlenose pliers, you can just push the pins out the
top very easily. It's going to be tougher if the socket is used...you might
have to crush the base with side cutters...so try to get a new one.

I just remove what I am going to use at the time. The socket base makes a
safe storage place for the tiny pins between projects. They are great any
place you want to experiment with part values and don't want to keep
solder-stressing the board which is what Chuck originally used them for.

I have a newly built XG1.
Wanted to try to calibrate the s-meter on my K2.
Problem is very weak output tone on 50 uv setting.
Not sufficient to light s-meter.
Can't hear tone at all on 1 uv setting.
All resistance checks are ok on XG1, all components look to be in correct 
locations, soldering looks good.

Connected to radio using the male-male adapter.
Bad xtal?
Any ideas appreciated.

[Elecraft] XG1 and K2 Signal Tracing

[Tom Mc]

Hi gang,

  I bought and built the K2 with the idea that I'd not only have a pretty
decent rig, but that I'd also learn something along the way.

  With that goal in mind, and realizing that I certainly have a lot to
learn, I'll respectfully ask the members of this list, what probably is a
pretty basic question:

  I've also built the XG1 signal generator and would like to trace the
signal through my K2.  I've read through the Troubleshooting section of the
K2 Manual (Revision B) and it explains how to build a signal generator.  Of
course having the XG1, I didn't build the one in manual.  However, the
signal generator shown in the manual seems to have a variable output.  For
example, step 5 in the low pass filter section (page 11 of the
troubleshooting section) says to adjust the signal generator to 0.14 Vrms
and then check various pins to see if the voltages are at certain levels as
described in the manual.

  The XG1 is not variable in its output, so would the voltages be more or
less in the same proportion to those in the manuals which started with a
signal of 0.14 Vrms? (I'll be honest I didn't check the XG1 to see what the
Vrms output is on it.)

  Or is there a better approach I should be taking to this whole thing?  As
I said earlier, the K2 is working fine, I just would like to poke around and
see if I can wind up learning something when I'm done.

Thanks for any help or ideas you might have to offer.

Tom in a lot of cases, the answer would be yes, but you must take into
consideration other contributing factors that may distort the result. For
instance AGC applied to a reciever stage would reduce the gain of that
stage.
I have found a great thing to do is to using the equipment you have at
hand, ie the XG1, make you own measurements at the points suggested and
record them. Walk through the whole procedure doing this. Now you have a
baseline for your rig using a specific array of test equipment. Once you
have done this, then as you re-align, fix, repair you always will have a
reference point utilizing your equipment. You will know whether the
performance has been enhanced or degraded.
A lot of time we will spin our wheels trying to get some reading in a
published procedure that is given to us only as a guideline. You are on the
right track. Get familiar with your equipment and keep a log of what you
find. You will be rewarded for your efforts. Good Show OM!

73 and Have Fun.
