Re: coax question

Gm Mike,

One of your comments triggered a thought here: you spoke about ordering only preassembled cables with connectors installed. Most preassembled cables use crimped connectors.

I’ve had bad luck with crimped “N” connectors pulling off the cable in tension. The cable shield slips away from the connector and pulls the center pin out of contact with the mating socket. In some cases the connector and cable separate completely, but I’ve found cases where the connector is attached but electrically compromised.

I use only soldered connector installation now.

The second thing to check is anything associated with your tower hazer installation which requires the entire feedline to be unsupported from the hazer to the ground. Look for any mechanical cycle fatigue stemming from the feedline moving in the wind. Same for rotor loops.

Hi,

I have copied my buddy Paull Holmes in Farmington about this issue.  He has two concerns.

First..

          My first question is if the cable with problems is genuine Times Microwave LMR-400 cable.  There are a number of companies (mostly Chinese) that are making "Times Microwave" alternatives.  Most of those are OK but do not have the quality control that the Times Microwave company does.  I also worry that some of the Chinese cable will say Times Microwave on it even though it is actually a "knock off". 

 

          If he is sure that the cable he is using is genuine Times Microwave cable then I would suggest that he give them a call and ask them what they believe might be the problem.  The cable should be able to handle a Kilowatt without a problem.  They would likely be interested if their cable is having problems.

 

Then in response to Keith’s point about UF version of LMR cable…

 

            The Times Microwave specs on their Ultra-Flex and the standard LMR-400 is -40 to 185 F degrees (operating).  Hard to imagine that the conditions are worse than that.  I believe that I would send an e-mail to Times Microwave and see what they say about the problem.  There are probably millions of feet of LMR-400 in use and the company has a stellar reputation.  I don’t know what the Time Microwave “knock off” specs are, probably not as good.

 

So more to chew on.  Contacting Times Microwave would seem to be first on the list after confirming it is truly Times Microwave.  And for goodness sake tell us the rest of the story.  I have LMR 400 Ultra Flex on my tower at the top.

Mike, the 'UF' version of all the LMR cable, which is the rubber jacketed, direct bury capable, highly flexible version is notorious for getting soft in direct sun and allowing the inner conductor to push out toward the shield when it is held in a bend or, even worse where it is cable tied and allowed to hang free.  This, of course, causes a increase in VSWR without any other symptoms.

 

I had this problem in EN52 with a 432 MHz LMR600UF feedline twice (it took me two direct failures at the same place to realize what was happening).  As you can imagine, the sun during a EN52 summer may be hot, but I'll bet it's much 'less-hot' then in New Mexico.

 

As a rule, I no longer use LMR 'ultra-flex' in my system unless it is inside.  I'm also VERY careful in planning my rotor loops and flexible RF cable attachments to avoid any locations where there might be a abrupt direction change.

Mike, 

Another thought: 

Before you trash your failed cable, try to find out where the cable assy failed using a vector network analyzer in time domain mode. That may help you analyze the failure.

Re: coax question

Mike WB2FKO
 

Thanks for all the responses, both on and off the list.  Here is a summary of the advice I have received:

* Only use the ultraflex cable for the portion of the feedline that is out of the sun
* Use 1/2 inch superflex aka Andrews FSJ4-50B heliax
* Use RG-213
* Use LMR-400 UF obtained from a reputable source like Times Microwave (I'm not sure where the various suppliers I have used get their feedline; perhaps it is China)
* Do not trust crimped-on connectors; make sure they are soldered

Bill's comment about crimping was clairvoyant.  As I did further troubleshooting over the weekend, I discovered that this is exactly what had happened on my 222 feedline.  It explains why I could not hear anybody on 222, so the transverter is probably OK.  The crimp connection pulled out at an N-connector junction just above the rotor and fortunately the main 50 ft feedline run was OK.  I replaced the broken jumper with a (far too long) section of one of my old rover feedlines and connected this to the 6m beam.  The 222 feedline allowed me to salvage Perseids and pickup six new grids. (Truth be told, I had worked 2 of those grids before but they were never confirmed on LOTW)

I have kept two of the dead cable runs, both used on 6m, but have already trashed 3 others over the years.  It will be interesting to see what a network analyzer reveals, although I don't have immediate access to one.

Thanks again for all the useful feedback.  Mike


2018 TAPR Digital Communications Conference -- Sep 14-16, Albuquerque

Brian Mileshosky
 

Greetings — 

For the first time in its 37 year history, the ARRL/TAPR Digital Communications Conference (DCC) comes to New Mexico, and will occur September 14-16 at the Sheraton Albuquerque Airport hotel.  DCC is an annual national conference, attended by hams across the United States and beyond, that highlights digital communications technologies, techniques, and capabilities currently being utilized within amateur radio or under development.  This event is the largest amateur radio digital communications conference in the nation, and attracts some of the most innovative hams from across the United States, Canada and beyond.

The weekend will be filled with introductory, semi-technical, and technical presentations, meals with speakers, technical demonstrations, prizes, and opportunities to establish or build relationships with some of amateur radio’s notable technical innovators. All amateur radio operators, from beginner to experienced, would gain from the practical information and demonstrations that will be offered at DCC.

Topics that are typically highlighted at TAPR Digital Communications Conferences as well as within the conference’s 100 page printed proceedings book: 

— Software Defined Radio (SDR)
— Digital voice (D-Star, DMR, P25, WinDRM, FDMDV, DRMDV, G4GUO, etc.)
— Digital satellite communications
— Global positioning system applications
— Precise Timing
— Automatic Packet Reporting System (APRS)
— Short messaging (a mode of APRS)
— Digital Signal Processing (DSP)
— HF digital modes
— Internet interoperability with Amateur Radio networks
— Spread spectrum applications
— IEEE 802.11 and other Part 15 license-exempt systems adaptable for Amateur Radio
— Using TCP/IP networking over Amateur Radio
— Mesh and peer to peer wireless networking
— Emergency and Homeland Defense backup digital communications in Amateur Radio
— Updates on AX.25 and other wireless networking protocols
— Other topics that advance the Amateur Radio art

The TAPR Digital Communications Conference also serves as the annual meeting of TAPR. Rocky Mountain Ham Radio, New Mexico has partnered with TAPR to serve as this year’s local event host.

Complete details about this year’s Conference, including the schedule of events, the presentation lineup, conference hotel information, and much more, can be found at https://www.tapr.org/dcc.html  Online registration is available at https://www.tapr.org/dccregistration.php   A flyer has also been attached to this email.

PRESENTERS WANTED: There are a few remaining speaker slots at this year’s DCC.  The kinds of presentations you saw (or gave) at the New Mexico TechFest would be perfect for the DCC audience.  If you are interested in presenting on an emerging or relevant amateur radio technical topics, technique, experiment, or project that you have been working on, please email both myself as well as Steven Bible N7HPR (steven.bible@...) with your thoughts.

Whether you attend for just a day or for the full weekend conference, we hope you’ll take part in this unique amateur radio event, meet some of amateur radio's technical innovators from across the United States and beyond, and gain from the practical information and demonstrations offered by the TAPR Digital Communications Conference.  The Conference continues its rotation to another part of the country next year, so don’t pass up a great opportunity to attend while it’s (finally) in our backyard!

Thanks and 73,
Brian N5ZGT


Ukrainian 222 Transverter Progress

Jonathan Fox - W0AMT
 

I finished the 222 transverter kit this past week and did some initial setup. Per the article on the NMVHF website by W7QQ and KK6MC I checked the gate bias and found it at 2.5 volts. I adjusted it up to 3.1. I did not have an opportunity to get an on-air report of the IMD improvement.

This past Wednesday I was able to make contact with NK5W on 222.110. However, I had some frequency stability issues. At first I was low by 2 MHz, after transmitting a few times I found I was  5 Mhz high. After ending the qso I went back to the assembly instructions and found that I had missed a detail. There are two mounting holes on the transverter board in addition to the mounting hole for the MOSFET. The instructions say to only use the #1 hole as using the #2 hole can cause oscillations. I missed that the first time. I am still using the #2 hole. I insulated the PC board from the metal mounting screw with a nylon washer.

I am hoping this change will improve my frequency stability issues. If not I will remove it completely and see what that does.

The WA5VJB 4 element cheap yagi I built for an antenna worked great for the QSO I had.

Is anyone available for a 222 qso this weekend? I would like to do another on-air check of the transverter.

Jon - I have a couple of 20W 222MHz amps that I am not using. You are welcome to one if you want it. They are RF Concepts amps, RF actuated, so they should work fine with little work. They don’t have the preamps as they were used for repeater links, but the Transverters Store transverter should have plenty of sensitivity without it. Let me know if you want it and can make arrangements to get it to you this week before the contest. - Duffey KK6MC

Sorry for the late notice, but I have been traveling a lot, just got back from a 4,000 + mile road trip and was not sure I was up to roving this weekend. I decided to, and with a limited route, so here is my itinerary.

I will start at the Moriarty convergence.

Saturday September
Time on Grid Time Out
1800Z DM75ba 1900Z
1915Z DM74bx 2015Z
2030Z DM64xx 2130Z
2200Z DM65uc 2330Z

I will overnight at home, perhaps operating from the driveway if conditions warrant or if anyone wants a QSO.

Sunday September
1400Z DM54xq 1530Z
1615Z DM64bw 1745Z
1915Z DM55xh 2045Z

I will return home to DM65tc. I can stop in DM64 on the way home if anyone still needs that.

You can reach me at (505) 228-5491 . Text is best as I have a record of who calls when if I get busy.

I will have 6M to 1296 exclusive. On Sunday I have allocated some extra time to work the guys in AZ. It should be possible from DM64 and DM55, but DM54 is only a mediocre site and I doubt it will hold up.

Enjoy the contest! - Duffey KK6MC/r

W0AMT/R September VHF Contest Plans

Jonathan Fox - W0AMT
 

I will have 6, 2, and 432 via an FT-817 and 222 via a Ukrainian transverter. I will be barefoot on all bands except 222 where I will have about 20 watts via a RFC amp on loan from Duffey.

I will start the contest in Los Lunas in DM64.  I will probably be set up in the El Cerro de Los Lunas trail head parking lot. If I can get my act together in time I will hike to the top and activate the  El Cerro de Los Lunas SOTA summit W5N/SL-015 

I have family commitments from 3:00pm to 7:00pm. I will be on from my backyard in DM65 after 7:00.

I plan to activate Mt. Sedgwick W5N/C0-001 in DM55 on Sunday morning. Depending on the success of that my stretch goal is the Cerro Rendija W5N/CO-013 summit in DM54.

The big 6m amp isn't ready yet (waiting for 7-16 DIN feedline connectors) so I'll use the KPA500.  I have every band you have.  Sorry not to get the 3 band 2.3, 3.4 and 5.7 GHz system ready in time. 

Do you have 10 and 24 GHz with you?

Sorry for the late notice, but I have been traveling a lot, just got back from a 4,000 + mile road trip and was not sure I was up to roving this weekend. I decided to, and with a limited route, so here is my itinerary.

I will start at the Moriarty convergence.

Saturday September
Time on         Grid                    Time Out
1800Z           DM75ba          1900Z
1915Z           DM74bx          2015Z
2030Z           DM64xx          2130Z
2200Z           DM65uc          2330Z

I will overnight at home, perhaps operating from the driveway if conditions warrant or if anyone wants a QSO.

Sunday  September
1400Z           DM54xq          1530Z
1615Z           DM64bw  1745Z
1915Z           DM55xh          2045Z

I will return home to DM65tc. I can stop in DM64 on the way home if anyone still needs that.

You can reach me at (505) 228-5491 . Text is best as I have a record of who calls when if I get busy.

I will have 6M to 1296 exclusive. On Sunday I have allocated some extra time to work the guys in AZ. It should be possible from DM64 and DM55, but DM54 is only a mediocre site and I doubt it will hold up.

Enjoy the contest! - Duffey KK6MC/r

Jim, I'll track you on APRS and try to work you on 2M from your stops.  If 2 is good, we can QSY to CW on 6M  - maybe 50.098 +/-.  I don't have antennas up for any other bands right now.

OK Bill. I don’t have 10GHz and 24GHz with me. I want to do a laid back rove for once. :^)=. I even debated taking 902MHz and 1296MHz, but did finally. I hope I can work the AZ guys from western NM.

Thanks for confirming the list. Hope conditions are good, but September is usually a bust here unless we head for CO. - Duffey KK6MC

Re: W0AMT/R September VHF Contest Plans

Bill
 

RR Jon,

I'll track you as best I can.  I'll listen on 50.125 and 144.200 both USB.  We will set up 222.100 USB contacts from the 144 contact.  Will use CW as required by signal strength.  You may reach me at 505.205.4253 (voice and text) Good Luck to you and have fun!

I will have 6, 2, and 432 via an FT-817 and 222 via a Ukrainian transverter. I will be barefoot on all bands except 222 where I will have about 20 watts via a RFC amp on loan from Duffey.

I will start the contest in Los Lunas in DM64.  I will probably be set up in the El Cerro de Los Lunas trail head parking lot. If I can get my act together in time I will hike to the top and activate the  El Cerro de Los Lunas SOTA summit W5N/SL-015 

I have family commitments from 3:00pm to 7:00pm. I will be on from my backyard in DM65 after 7:00.

I plan to activate Mt. Sedgwick W5N/C0-001 in DM55 on Sunday morning. Depending on the success of that my stretch goal is the Cerro Rendija W5N/CO-013 summit in DM54.

ARRL SEPT VHF

Jonesy W3DHJ
 

Saturday was grim. Sunday was probably grimmer.
My ONLY front range ("regional") QSOs were with
Ken, W0ETT, Duncan, WE7L, and George, AB0YM/r.
Those three folks made up 84% of my total contest QSOs.
Thank you fellas, for I would've given up and quit FAR sooner than I did.
Special thanks to Duncan, WE7L -- who spent a little time over the
weekend, trying to boost my spirits now-and-then.
My only other Colorado contest QSO was with Keith, W9RM.
Then there was Larry, N0LL.
THAT WAS IT!!!!!!!!!!!

I had "hopes" during the Broncos halftime - nothing.
I waited until a half hour after the Broncos game and gave up.
I monitored 2M during the 1 hour drive back home - zilch.
I should've quit at 2PM at my last QSO.
But for AB0YM/r, it was a waste of time to haul the 432mcs equipment
and put up the antenna at each stop.

I give up.
I've decided this is/was my last ARRL SEP VHF.
If most of the region's VHF operators think the ARRL SEP VHF
is not worth showing up for, who am I to buck the trend.

It's simply not worth the wear and tear on the equipment, the vehicle,
and me to spend Friday for vehicle setup, Monday for teardown, and waste
Saturday and Sunday listening to receiver static while swatting flies.
