Re: [Elecraft] Rick & antennas...

[Ken]

For limited space, there is nothing wrong with bending the ends back (or 
down).  My novice antenna was an 80/40 fan dipole with the 80m legs bent 
back about 135 degrees.I feel that an antenna with full length 
elements, even if the ends are bent back,  will perform better than one 
that uses loading coils.   The reason I say this is that, when you have 
a full half wave antenna, most of the radiation comes from the high 
current center half of the antenna.  The ends do not radiate nearly as 
much as the center portion.

[Elecraft] cocoaModem and Mac OS 10.11.2

[Bill Frantz]

I am trying to get my world back together after buying a new 
MacBook Pro which involved upgrading to OS 10.11.2. The good 
news is the the K3 and P3 utilities seems to work, so I'll take 
the KX3/PX3 etc. ones on faith.


The bad news is that cocoaModem running PSK dosen't show any 
signals in the waterfall. Table View does decode a number of 
signals and you can move one to a VFO by clicking on it as 
normal. Output seems to work, and I was able to make a QSO, but 
no waterfall is a significant problem.


fldigi seems to work, although I haven't given it a through 
workout yet.


Does anyone know if there is a version of cocoaModem newer that 
2.0 or that works on 10.11.2?


Thanks Bill AE6JV

[Elecraft] MMTTY not keying transmitter

[efortner]

I am trying to run RTTY FSK with my elecraft K3s SN 10326  K4KAY Earl. I am
using MMTTY software and Timewave Navagator. It receives well and appears to
be working properly. Every thing looks right on the MMTTY screen and the
PTT, CAT, FSK leds light on the Navigator. The Tx led below the power button
on the K3s lights but I get no RF out of the K3s and the KPA 500 will not
key when switched to OPER. I have the K3s set to data and MMTTY set to Radio
Command and TX Port is com-TXD(FSK) USB.

 

I have checked on the comports and they are up and correct.  Anyone have any
suggestions.

Re: [Elecraft] P3 cw waterfall

[d...@lightstream.net]

Barry,

It's as Fred said, it changes as a function of the "Rate" setting when
running in the "Fixed" mode, however it does so as a side-effect of the
slower screen refresh rates. I was hoping to be able to dramatically slow
the waterfall to the point of it displaying 3 to 4 minutes of traces, but
without altering the refresh rate of the spectrum display. I don't think
that's currently possible though.

Re: [Elecraft] cocoaModem and Mac OS 10.11.2

[Bill Frantz]

I have fldigi on my machine and it seems to work with MacOS 
10.11.2. I admit to being old and set in my ways. I learned on 
cocoaModem and am used to it. The features I like the best are 
being able to decode the past in the waterfall, and dual RTTY. I 
just made a RTTY contact with HH2/N5JR using the dual RTTY 
function. Although the waterfalls and the two tuning meters did 
not show any signals, I was able to tune the DX with the K3 
tuning meter and tune the pileup with my ear on the subreceiver. 
cocoaModem decoded both DS and pileup.

There is also a 2007 version.
I believe there was a bug in the 2008 version and some folks went back to
the 2007 version. I don't remember what the issue was, but it wasn't fixed
before the support went away.
I have 2005, 2007 and 2008 versions.
I can send all three to Jeff if he is willing to host them.

Thanks to Mike/VP8NO the problem is solved.

The solution was to check the 'Data' box in the subRX filter selection page.
It was unchecked, not sure why, or how I missed it during setup.

Once again the value of this list is exceptional.

Thanks again Mike,

[Elecraft] FS: NOS Pomona brand BNC Adapters

[Gary]

A few years ago I offered new/old stock Pomona brand BNC to binding post
adapters to the group with great response. I'm happy to report that I've
located more of these and am again offering them. They are handy adapters
especially for the KX3 antenna port when adapting to a random length wire
antenna. The model is 1296 and Pomona's spec sheet for this adapter can be
found at http://www.pomonaelectronics.com/pdf/d1296_1_02.pdf.

 

As before I'm offering them through eBay with payment via PayPal. The
auction can be found at http://www.ebay.com/itm/-/121837467266. The auction
number is 121837467266. I'm offering them with free shipping in the USA and
Canada. If you have any questions please email me directly at n6...@cox.net.
I'm way behind on my group emails so please email me directly versus through
this group.

Re: [Elecraft] P3 transmit monitor

George,

I’m in the same boat. I like digital modes and wanted to be able to watch my 
ALC and VSWR at the same time. The P3TX Monitor was less expensive than the W2 
wattmeter and it kept me from having to add a box to my shack.

Except for a few frequencies, I really like it.

[Elecraft] Antennas with resistor and OCFD.

[Brian D. Comer]

I think stating any particular antenna configuration is unacceptable is
ignoring what could be an ideal antenna for a given situation.  As I
understand  it  a rhombic  uses a resistor, and sometimes works quite well.
On 160 I have an OCFD 1/2 wavelength that is goes from one side of the end
of a very small canyon  to the other.  The net result is that the center of
the antenna is about 80 feet above ground, the ends are only 50 ft above
ground. On flat ground this would be a NVIS antenna being so low; however,
with the ground 100 feet to the west at the same height as the antenna and
the ground 100 feet to the east being 300 feet below the antenna  I suspect
the pattern looks more like a beam pointing east. Considering I have broken
two important rules, the antenna is OCFD, and is on average it is well under
1/2 wavelength above ground it is amazing I can work the east so well.

Re: [Elecraft] MMTTY not keying transmitter

[ab7r]

If I recall with the Navigator there is a file that must be in the MMttY folder 
for EXtFSK.  Use the one supplied by Navigator.  then in the COM port window to 
select the keying port you select EXtFSK.  Its been awhile :)

then I think a small control window opens to select the COM port for extfsk to 
use.  Use the com port Navigator created for FSK.

Sorry for my dimness, but I've tried Tracking mode and Fixed-Tune

seeing a change in the waterfall speed.  Exactly what do I need to do

In PowerSDR, the Update Period (rate) directly and obviously changes
the waterfall speed.  And the P3?

set up several spans in the buttons.  I set the averaging to max on the 
spectrum display and min on the WF, and I run the monochrome WF option. 
 Other than those, I find the Elecraft factory options tend to work 
very well.


I think one complication is that the SVGA option complicates the 
operation a little and there are things that work in the P3 display but 
not in the SVGA and vice versa.

In PowerSDR, the Update Period (rate) directly and obviously changes
the waterfall speed.  And the P3?

I had a similar issue on my Chicago city lot. My solution was a loaded 
dipole for 80M that also resonated on 40M. You can buy antennas like 
this here.


http://www.hypowerantenna.com/products/dipoles  Look at the 2B4080L

As others have noted, the major advantages are 1) predictable pattern 2) 
fed with coax, so they can be choked to kill common mode feedline 
current. Common mode feedline current makes a noisy antenna and puts RF 
in the shack.


I've used the 160/80 M version of this antenna very successfully in 
three locations, adding a 40M fan element to cover that band.


Barry's antennas are well designed, but their construction is a bit 
light weight for high stress applications (like 150 ft up in tall trees 
that sway in the wind). They're fine for lower stress installations. For 
the antennas I've built based on his designs, I've bought the loading 
coils and built the rest. His standard design was more than strong 
enough for my Chicago installation at about 40 ft between fixed points 
(not trees).

Re: [Elecraft] Disappearing Line Out Audio for Sub Rx

[KK1W]

Wayne,

I haven't seen any further conversation about Dennis's issue. 

I'm having a similar problem with data modes and the sub receiver. Here's an
example using a strong CW signal as an example to make it easy to hear:

1. Tune in a strong CW with the subRX off.
2. Press the A/B button twice to copy all info to the subRX
3. Turn on the subRX (tap SUB)

At this point you will hear the main RX in the left speaker, the subRX in
the right - as expected. It truly is the subRX audio as you can tune it and
the right channel follows the tuning.

Now:

4. Change mode to DATA.

The result of this is you will hear the CW signal in the left channel change
pitch but the CW signal in the right channel will remain unchanged - again
as expected.

5. Press the A/B button twice to copy all info the subRX (the only thing
changing should be the mode)

Result:

The audio remains unchanged in the left channel but the right channel goes
dead. - NOT EXPECTED!

If I change the mode back to CW, then double tap the A/B button everything
returns to normal. MainRX in left channel and subRX in the right.

This makes operating split in RTTY and trying to listen to the callers
impossible. Perhaps this is by design?

No logging software or K3 utility connected at the time, the K3 port is
closed.

Equipment:

K3s #00120
Firmware:
uC = 05.38
d1 = 02.86
d2 = 02.86
FL = 01.25
dr = 01.03

Thanks,

Jim/KK1W

I have noticed that I am flat topping on voice peaks which is a reminder
that I need to turn the power down on the K3 to the ALS-600.

I find the PEP wattmeter and SWR display useful.  Yes, it compressed the
FFT and waterfall some, but it was a trade-off that is now "normal".

I am satisfied with it and have it enabled at all times.  While I wish
the TX monitor could also show an FFT of the transmission, I understand
this is not possible.  At least this way I am able to monitor my TX
signal at the output of the amplifier.

Re: [Elecraft] Antennas with resistor and OCFD.

[Barry LaZar]

Brian,
 Be careful of your logic. The reason a rhombic works so well is 
that most rhombics are 2 or more wavelengths long per leg. However, 
putting in a resister makes the beast directional toward the resister, 
not all bad nor inefficient. But the T2FD type antenna is only a 1/2 
wave long on the lowest frequency making it more efficient as you go up 
toward 10 meters.


I have been reading a lot of comments on antennas here, some are 
correct and some just may be close at best. Let me reiterate something 
I've said earlier and regularly. There is NO perfect antenna. Every one 
is some compromise in one way or another. in my case, I need to deal 
with 40 meter space with a desire to use 80 meters. So, part of my 
horizontal antenna is bent down toward the ground. It fits. Do I have 
the best antenna?? No. But, it does fit.


OCFD antennas are not really bad antennas if you follow the rules of 
horizontal antennas. If the antenna was fed in the center, it would be 
50 Ohms or nearly so at its 1/2 wave length. Above that, even multiples 
of the 1/2 wave frequency, the feed impedance would be very high. So, it 
was figured out that you can feed off center and could find a spot that 
would not be awful at the even harmonics. A 4:1 current balun will take 
of most of the impedance issue and bring it down into range of your 
tuner. A good balun will have a loss of less than 1 db. If you use good, 
low loss coax, losses will not be bad.


The 1/2 wave dipole, center fed dipole. fed with open wire and a 
balun at the shack entrance makes a good antenna, and the losses may be 
a slight amount lower than the OCFD, but it follows the rules of 
horizontal antennas that are a specific height.


There is nothing in ham radio that is argued more passionately than 
antennas, with maybe the differences between Windows and the Apple OS.

Barry

I think stating any particular antenna configuration is unacceptable is
ignoring what could be an ideal antenna for a given situation.  As I
understand  it  a rhombic  uses a resistor, and sometimes works quite 
well.
On 160 I have an OCFD 1/2 wavelength that is goes from one side of the 
end
of a very small canyon  to the other.  The net result is that the 
center of
the antenna is about 80 feet above ground, the ends are only 50 ft 
above
ground. On flat ground this would be a NVIS antenna being so low; 
however,
with the ground 100 feet to the west at the same height as the antenna 
and
the ground 100 feet to the east being 300 feet below the antenna  I 
suspect
the pattern looks more like a beam pointing east. Considering I have 
broken
two important rules, the antenna is OCFD, and is on average it is well 
under

1/2 wavelength above ground it is amazing I can work the east so well.

Absolutely!  Situations differ dramatically.  A low angle radiator on 80 
in the evening is likely to underwhelm you if your need is to 
communicate over 150 miles.



 As I
understand  it  a rhombic  uses a resistor, and sometimes works quite well.


Ummm ... rhombics *always* work well for their intended use. 
Unterminated, they are bi-directional.  With the terminating resistor, 
they are unidirectional in the direction from the feedline to the 
terminator.  Since terminated rhombics are usually 2 or more wavelengths 
on a side, they have very narrow beamwidths with a big F/B ratio, low 
radiation angle, and high gain.


They were used on point-to-point HF circuits in the 30's through maybe 
the 60's or so.  I worked coastal marine in 56-57.  We generally used 
V-beams with wider beamwidths since our targets were ships that moved 
around, but we had a couple of rhombics, one aimed at NMO in Hawaii. 
Tap the key at 5 KW and they told us we were QSA 11R5:-)


OCF's can serve well in the right situations and with the right 
precautions to mitigate the downsides.  The infamous B folded dipole 
was never billed as anything other than what it was ... an antenna with 
a non-inductive resistance that pretty much swamped any effects from the 
antenna, and could be used 3 - 30 MHz, in the right situations.


Tom Schiller, N6BT, likes to show his "illuminator", a 300 W light bulb 
fed through a common mode choke.  He even put three up as a "phased 
array.  Any RF in any conductor will radiate.

Does anyone have any experience installing the FTDI  drivers on windows 10
for the K3/0 mini. Windows 10 does not appear to install them automatically.
I cannot find instructions on the web site.

 

Thanks 73

[Elecraft] K3 has "Zero" Output??!!

[Mike Furrey]

Just as the 160 meter contest was starting my shack computer crashed big time ( 
power supply failure) . I unpacked my other computer, loaded and configured 
software, installed drivers for usb to serial cables and then it was time to 
give it a quick test before contesting. My dummy load was still packed (new qth 
here) so I turned the power output on the K3 down to "Zero" and hit F4 to send 
my call. Much to my surprise I heard my call and a report come back to me!  I 
hit F2,  sent my exchange and completed the Q. NO3M must have  a suburb set of 
ears to hear that "Zero" output!
S ... when I turned the power output down to "Zero," What is the power 
output?? I only have a Bird meter with a 250 watt slug in it and the meter 
doesn't wiggle at "zero" output. 
That was a fun Q!

Re: [Elecraft] Rick & antennas...

[j...@kk9a.com]

How do you know that it works well?  Low SWR or even working DX is no
indication of antenna performance. I really do not understand the
popularity of OCF antennas. They can have considerable common mode current
making them susceptible to feedline radiation and RF in the shack.  Simple
dipoles or fan dipole for the desired bands is a much better option.

The Buckmaster is recommended to be installed as an inverted V. That's
sweet that the E Tuner gets along with it but I have the 3,000w version
and run full legal limit on all bands (where allowed) that it operates on
without the need to use my tuner. Not high performance eh? Funny stuff. I
suggest anyone considering this fine antenna consult the  eHam reviews of
it by people who actually own the antenna & have experience with it.
Comparing a beam antenna to a wire is sort of ridiculous IMO for what
should be more than obvious reasons. Lotsa haters out there as usual.

Re: [Elecraft] P3 transmit monitor

[George Danner]

Guys,
For me the Transmit Monitor was exactly what I expected when I ordered it.
It replaced my bench scope which took-up too much space on my desk and 
relegated to a corner and integrated the power meter/VSWR into one display.
Now my P3 is on a shelf in front of me and in my field of view when 
transmitting. The SVGA is below on the desk top.
I do like having the confidence of seeing my modulation envelop. Takes me 
back to the days of broadcast AM In Tampa in the 60s.


I too would have liked to have a spectrum display as well, but knew when 
ordering it was not too be!


Hopefully someday Elecraft will create such a product; but I doubt it will 
be anywhere in the price range of the Transmit Monitor.


I'll give change for my $0.02.

Re: [Elecraft] OT: B & W antenna

[John Kramer]

I would not touch any antenna that uses a resistor. That is what a dummy load is
after all - great SWR but the losses are huge.

I built a T2FD when I was newly licensed back in 1984 (when I didn’t know any 
better),
from an article in Practical Wireless. I used the specified resistor and built 
it according to spec,
and put it on top of a 220 ft  building, raised 20 ft above the building. Any 
antenna
should have worked really well at this height being totally up in the clear. 
The SWR
was great across all the bands, but I was very disappointed in it’s 
performance. 
I have learnt a lot since then…

BTW nothing wrong with OCFD antennas, they work well on their harmonic 
frequencies as a multi band antenna, provided they are installed properly, and 
a good CMC is used in the
feedline. No, not an ugly Balun which might give you 1000 - 1500 ohms choking 
impedance
if you’re lucky, but a proper CMC with more than 12 000 ohms choking impedance.

I would rather hang a good OCFD with a quality 4:1 Balun at the feed point, and 
a 
quality CMC choke for 80 - 10 just before the coax enters the house, rather 
than fiddle with
8 dipoles yuck…

Better yet, would be to use an EFHW 80-10 1K built by www.myantennas.com

Sure. Unfortunately, my email computer is not in the shack, and it's

which menu setting does that. :)  Poke around the menus and the manual.
It's there.

On the SVGA, it's possible to get more than a minute on screen.

Ummm ... rhombics *always* work well for their intended use. 
Unterminated, they are bi-directional.  With the terminating resistor, they
are unidirectional in the direction from the feedline to the terminator.
Since terminated rhombics are usually 2 or more wavelengths on a side, they
have very narrow beamwidths with a big F/B ratio, low radiation angle, and
high gain.


Quite so but it's worth noting that the unidirectional characteristics
obtained with a terminating resistor did not result in any additional gain.
Instead, the resistor absorbed the RF that would have been radiated on (or
received from) the reciprocal heading, giving the array its unidirectional
characteristic.

Yagi's, quads and similar arrays gain a stronger main lobe by suppressing
radiation in other directions.  

A rhombic is a classic example of how the best design is not always the
design that radiates the most RF. 
The problem with a rhombic for Ham use on the HF bands is that they tend to
be an absolute beast to try to rotate.

Re: [Elecraft] OT: B & W antenna

[WILLIS COOKE via Elecraft]

It is true!  It makes a good antenna that tunes easily it you want to use a QRO 
transmitter work like a QRP rig with a good antenna.  My Dad earned a Novice in 
the mid seventies at the time that my wife earned an Advanced and I earned an 
Extra.  He called me one evening to report that his club in Denver had an 
article in the newsletter for an antenna which had a good SWR on all novice 
bands and worked well.  They took a 30 foot aluminum vertical and connected a 
75 watt incandescent light bulb between it and ground.  I told him that in the 
mid fifties when I was a Novice we used the same antenna, buy omitted the pole 
and kept it in the shack, but we called it our dummy load.  It glowed brightly 
with a 75 watt novice transmitter and radiated a little so that we could talk 
to each other across town with our dummy loads.  Any dummy load will radiate a 
little unless you keep it in a Faraday Cage. Willis 'Cookie' Cooke,VP TARS for

Re: [Elecraft] Rick & antennas...

[n9tf]

John, 
  
As a user of an 80M OCF dipole, I knew it was going to be a compromise. My goal 
was to be able to put up an antenna on a small lot that would get me on the air 
on 80 and 40. I don't have room to run even a full 1/2 wave dipole for 80m, or 
a lot of wires, but the OCF dimensions (45'/90') fit in to my lot with a bit of 
zig-zagging. I don't use the OCF on anything higher than 40m as I have a small 
beam for the higher bands. 
Yes, common mode current can be a problem if not designed properly. I use a 4:1 
current balun and an additional 10 turn choke at the feed point, in addition to 
a single point ground system. No issues at this location. 
I agree simple dipoles or fan dipoles would be desired. In my case, I do not 
have 66' in both directions, of the direction of interest, to string a full 
size 80m dipole. But I can get 45' in one direction and the 90' leg does take a 
turn at 75'. 
Point is, we put up what we can, understanding the compromises (antenna theory) 
in the space we have. 
  
One point of relative (A/B) comparison I can share . The 80m OFC is resonate of 
course on 17 and 12 meters. I have a rotatable trap dipole (D3W) on the tower 
for 12/17/30m at 42'. The OFC is at 35'. When comparing signal strength of the 
two antennas to EU, which is where the OFC is broad side to on 17m, the OFC is 
about 20DB less signal strength than the rotatable trap dipole. So yes, the OCF 
is a compromise. 
  
There has been one benefit to the OCF in contesting, and that is in the NAQP 
and SS contest. With it's height above ground at only 35', it works well for 
close in state side contacts on 20/40/80. It comes down to what the operators 
goals are, and understanding antenna theory.
