Hello Dave. Saw people calling you yesterday. Good on the Winter Es yesterday. Almost as much fun as the Summer Es. Good on VK4MA.  Only VK worked here was VK4HL. I was heard by several VK4's, VK3's and a VK5.

Also heard by 3D2AG. All on JT65A. Form some reasons most VK’s are still hanging on to the JT65 mode. Have to keep two screens up and active now. More fun. Good DX this 2019 year.

6m and 10m, coast to coast, on Wednesday evening.  From here in south-central Texas, I worked AI5I and K9VSW in NM.  For a short while, 6m was also open from the western US to Australia!  VK4MA cold-called me on 6m FT8 after I completed a QSO with Arizona.  I wasn't even using my 6m yagi at the time, rather a 40-6m OCF dipole.

So, why am I on the NMVHF group from Texas?  I lived in Santa Fe and Albuquerque for 7 years and I go back up there semi frequently.  Was there for the CSVHF conference and VLA tour in 2016.  Green chile keeps calling me back.

New Mexico TechFest -- Presentation call reminder

Brian Mileshosky
 

Greetings — 

If you are interested in providing a presentation, posterboard, or demonstration at the 2019 New Mexico TechFest next February, this is a kind reminder to submit your proposal(s) before the January 1 deadline which looms just a couple weeks from now.

CALL FOR TECHFEST PRESENTATIONS, POSTERBOARDS, AND DEMONSTRATIONS: The New Mexico TechFest seeks presentations, posterboards, and demos on emerging and relevant amateur radio technical topics, techniques, and applications.   If you’ve been working on a special project, are experimenting with a technical topic, or have discovered or adopted a technology or technique that you’re applying within amateur radio, TechFest is a great venue to share your knowledge with the amateur radio community in a casual and friendly environment.  Presentations will generally be 50 minutes in total length.  Shorter posterboard talks and demos can occur at various times during the event.  AC-powered tables will be provided to facilitate presentations and demos.  Hams interested in providing a presentation, posterboard, or demonstration are asked to submit a brief summary/abstract of their proposed topic for consideration by January 1st. Visit the New Mexico TechFest website for submission details and key dates.

The fifth annual New Mexico TechFest, an ARRL-sanctioned operating specialty event organized by Rocky Mountain Ham Radio - New Mexico, will take place Saturday, February 23, 2019.  TechFest features a day of quality presentations and demonstrations provided by some of New Mexico and Colorado’s leading technical hams on a variety of emerging and relevant topics within amateur radio.  The event’s purpose is to help expand attendees’ technical knowledge, facilitate collaboration, and encourage the discussion of new ideas with one another.

TechFest is open to all interested hams and will occur at the New Mexico Veterans’ Memorial Event Center located at 1100 Louisiana Blvd SE, Albuquerque, NM 87108.  Admission is $10.  Online registration will open the week of January 6, after the event’s presentations are announced.

Presentation-related prizes will be drawn throughout the event. Refreshments including coffee, water, and light snacks will be available. Optional lunch, catered by local small business, will be available at an additional cost.

GEMINID M/S peak - operating summary

Keith Morehouse
 

The GEMINIDS, one of the more vigorous showers of the year, was forecast to peak this morning at 1230Z.  I always try to be on during the peak of a big shower, since you don't really know what might happen.

Meteor activity started at the 0100Z shower radiant rise and seemed to grow steadily.  Sometimes it's hard to really measure the quality of a shower, because operating activity can vary widely by time, day of the week, where you are and what direction the meteor stream is moving.  Geminids radio activity is mostly north/south, with the meteor stream moving roughly east to west, so the number of potential contacts is lesser then a shower which favors east/west paths.  Meteor burst strength and duration seemed strong on 6M but few 2M attempts were made.  Activity started dropping off around 0300Z as operators left the air for the evening and I decided to do likewise to make it easier to be awake and ready for the peak.  At 0300Z it was looking like the 2018 Geminids might be worthwhile, which is not at common these days.

I was up at 1100Z (4AM !) and at the radios by 1130Z with large coffee in hand.  Activity was good on 6M for the early hour and meteor burst strength was stout and duration very long.  Some bursts on 2M were exceptional (5-10 second duration).  This went on through the 1230Z forecast peak but it was hard to really notice when or if there was a peak.  I would say peak activity was anytime between 1100 & 1400Z.

I only tried one really long-haul contact, a 1325 mile attempt with a well equipped station in Alabama on 2M - WA4CQG.  Unfortunately, we did not complete as AL is my final "in-range" state on 2M - in other words, workable on terrestrial modes within the normal accepted maximum range of 1350-1400 miles (both NC and FL are close, but just over this distance).  Several 2M QSO's were easily completed between 900-1100 miles on the shower radiant to the NNE and I worked 5 new 2M grids,  EN19, EN29, EN00, EM11 & EM21.  Between 6 & 2M, I worked approx 35 QSO's.  I try to concentrate on 2M during showers, but I downloaded my 'stations heard' map from PSK Reporter, showing both 6 & 2 decodes and attached it to this message.  There were several stations copied out beyond 1200 miles on 6M.  The Geminids are not known as a good DX shower, since they just have "average" velocity.  The upcoming  January QUADRANTIDS is a high velocity shower, where the earth pretty much head-ons the stream and is well known for producing 1300+ miles contacts.

The Geminids are not done - there will be plenty of activity tonight and even more early tomorrow and Sunday morning if you want to check it out.  For those who don't know, pretty much 100% of M/S activity is via the MSK144 mode of WSJT-X now.  The old days of high-speed CW or real-quick-talking SSB are long gone, although they were fun.  Be sure you have the latest version of WSJT-X (V2.0) - the encoding has been changed for this release to make MSK144 and FT8 more contest-friendly and V2.0 is NOT back-compatible with earlier versions when using these modes.  This does not seem to be a problem on VHF, but HF op's are having fits over it :)

Don't neglect 222 MHz - many long haul contacts are made during showers on this band.

Good Luck - get on the rocks !

Re: Chineses TCXO for 28 MHz IF 2M transverters

Keith Morehouse
 

John, thanks for digging up that info.

I did buy a couple and they were certainly cheap enough to just throw away if they don't perform.  I don't have a phase-noise test setup and I understand that this is one of the more important specs in any oscillator.  But, I do have a real spectrum analyzer and will do a critical evaluation of them, at least as much as I can.  If anybody out there does have a phase-noise measurement box, I'd be happy to send one of these.

The cheap Chinese unit I bought for the FT-817 was evaluated for phase-noise (not by me) and found to be "pretty good" for the price - as good as the stock Yaesu (which isn't that great).  Unfortunately, a large percentage of amateur radio gear isn't stellar as far as phase-noise is concerned.  Since this is for 144 MHz, a band where I have no other local stations, a little bit of ragged extra bandwidth isn't really a show stopper.  I'll throw it in the same category as the nasty APRS beacon here in the valley that lights up a significant amount of spectrum every time it does it's thing.

I bought a TCXO advertised just like this as a drop-in for a Yaesu FT817 and it worked fine and was dead on freq, out of the package.  It was 20% the cost of a Yaesu equiv part.

Re: Chineses TCXO for 28 MHz IF 2M transverters

Hi Keith,

One thing about ref oscillators:  I use 5 volt dc powered oscillators especially portable ops. They need a regulated and filtered supply so one must have adequate headroom for the regulator. 10 or 12 vdc oscillators won’t get it done.  OK for home use. 

I’ve used several CTI-196 units but they’re pretty expensive now at abt $30 each. They do sine outputs at 10 ^-5. Good enuf for 10 and 24. Pyrojoseph still has them on ebay. 

Looking for smaller units a little smaller than a postage stamp. Need to be 5v, sine out at 2-3 volts pp 10 MHz.

Alternatively, use a LPF such as these from QRPLabs to derive the sine from the square wave. I did that for the Si570 synthesizer output to drive an old GE MASTRII transmitter chain to make a 6m beacon; works great.

Given that you are probably driving a mixer that is basically a diode switch, it's not clear to me that a square wave would be a problem.  Even with a sine wave LO, you are creating mixing products around multiples of the LO frequency, and any decent amount of filtering downstream of your mixer takes care of that problem.  Does anyone know more about this topic?  I have considered a 222 transverter LO using a MEMS oscillator chip (square-wave output), and was thinking that LO filtering would not be necessary.

8 cell AA battery holder for Standard HT's

Keith Morehouse
 

Anybody have a Standard HT ?

I just bought a 8-cell AA battery holder for Standard models C228A, C528A, C628A, HX190, HX240 and possibly others that used Standards RBP-120, CNB-152 or CNB242 batteries.  Unfortunately, I have an odd-ball HT that uses a different size case.  You can see the item here, mid-page - the CPB888:


If you can use it, let me know - first come, first in - I'd take a $20 for it via Paypal or whatever, and ship it to you for free (no - the battery cells are not included).  They don't have a like model for my unit and it's not worth sending back.

Designating non-RTTY digital QSO's in future VHF contest logs

Keith Morehouse
 

The following is from N5RZ, who is doing the results write-up for the ARRL September VHF contest.  Up until now, there has never really been a official position on how to log QSO's made using any WSJT mode.  Some just use 'PH' for phone, since the radio is usually set to USB and others always used 'RY' to designate the QSO as something different.  Now we have a preference for 'DG', which I will begin using next month in the January VHF contest.

-W9RM

****************************************
Notes and Observations 

FT8 usage continues to surge, as was most apparent this September during an event with limited propagation enhancement. While 6-meter FT8 is expanding and well established, in some areas 2-meter FT8 activity is just taking root. Even though it is not required to specify FT8 (or other digital modes) in Cabrillo-formatted logs, it would be great to get a handle on how many QSOs are made via the various digital modes. To that end, for future contests, the Cabrillo specifications have recently been updated to designate “DG” as a mode representing nonRTTY digital modes. Things are also apparently changing in the way VHF QSOs are being conducted, and it would be great to somehow track the recent technology changes. The contest community is actively discussing ways to obtain that information.  -N5RZ

Re: 6M sporadic E

I saw the notice a bit late but did get on just before 0200. Heard a couple of regulars from the southeast chatting on .130. Worked one station calling on .125 SSB (EM52)and then tried a CW CQ on .098. Got a reply there (EM57) but the band faded just just after we exchanged grids. Could still hear the guys on .130 but very weak by then.

I have 145 DXCC on 6M and still need VK :)  I also frequently make the mistake of not actively watching 6 during the winter/spring period when the chance of TEP links is best.

It appears MOST of the VK/ZL trans-Pac DX activity is on JT65 or FT8 - at least that's how it's been the last few days.

I worked 10 stations on 6m SSB from 0055z to 0137z. There was a few more operators heard on 50.125 but I made no effort to work them there. Path rather broad from MS in the south to WI in the north. Not sure if the band opening continued as I shut down for a phone call and then the hungries.

I had my band-monitoring SDR up on the 2nd computer screen and was tipped off by the big bunch of beacons.  I saw a couple of guys on FT8, all running version 1.9 or earlier, so I don't know who they were.  I've been doing MSK144 meteor scatter so I have V2RC5 running.  I also saw a few guys on SSB, but nobody CQing.  It doesn't appear anybody is really watching the prop indicators this time of year.

The CW window, which technically is still there, is usually empty unless it's a contest weekend or the opening is so good, the QRM level above .125 is bad.  With FT8 on the scene, who knows if the QRM level will ever be high again ;)

The opening started a little before 2300Z and was still going, by the looks of the beacons, at 2340Z when I went for dinner.  We are entering the secondary Es season, so there should be increasing activity.  Be aware that this is also the PRIMARY Es season south of the equator and it's not unknown to get good enough sporadic E up here in the northern hemisphere that we can link into the south Pacific or VK/ZL regions on 6.  With low sunspot counts, the likelihood of this (TEP) is lower, but it has happened.  VK/ZL was working trans-Pacific on 6 last evening, into South America (south of the equator).
