Crossing State Lines

By: w6csn
27 April 2024 at 03:12

The outdoor amateur radio adventures documented in this blog so far have taken place entirely within my home state of California. Recently, I took off by car to visit family in Washington state. This wasnโ€™t really a POTA oriented vacation trip but if I played my cards right there might be some time to activate parks in both Oregon and Washington.

Studying the POTA map, I found Row River National Recreation Trail US-10009 not far off I-5 near Cottage Grove, Oregon, about an hours drive north from where we had stopped the first night.

Row River Trail is a BLM unit maintained with help from the Army Corps of Engineers that offers miles of level recreation trail along the shores of Dorena Lake.

Row River feeds into Dorena Lake at the east end and continues past the dam at the west end of the lake.

For radio accessory management Iโ€™ve been testing out a new toolbox solution from Harbor Freight. The lid includes a clear plastic cover that snaps closed over several compartments in which you can store adapters, antenna bits, patch cords etc.

An inside tray holds coax and antenna wires, while the main box can be used for bulkier items, like spare LiFePO4 battery backs, arborist throw kit and such. The main box plastic is a little thin, which makes it a challenge to get the lid to align and snap closed properly, but then again it was 12 bucks at Harbor Freight.

It turns out I drove farther up the road past Dorena Lake than was necessary and where I ended up activating from actually had some overhead power lines cutting through the trees not far from the picnic table that had sun.

I definitely needed to keep my antenna and lines well clear of these wires and I hoped they wouldnโ€™t be a source of noise.

I deployed a 20 meter EFHW on a Sparkplug Gear 64:1 unun, an antenna system I hadnโ€™t used in quite a while. Although I had scheduled the activation from the hotel earlier in the morning, I used Sotamฤt via the Garmin InReach Mini to make my spot certain as there was no cell service in the canyon.

The springtime morning in the Oregon countryside was bright blue with temperatures is the 70s. I can imagine it getting really toasty here in the summertime.

After about an hour, Iโ€™d logged 10 contacts needed for a complete activation. One of the challenges a QRPer faces when doing POTA midmorning on a weekday is the relative lack of hunters. Youโ€™re out playing radio while everyone else is at work!

Since we were โ€œon the roadโ€ we didnโ€™t linger any longer than necessary. Besides, it was well past time for my first Dutch Bros coffee of the day!

While I very much wanted to get an activation from Dash Point State Park on the shores of Puget Sound, my family and travel schedule simply did not leave enough time.

On the return trip, back in California, I again pulled off I-5, this time at Castle Creek Drive going southbound just past Dunsmuir. Castle Crags State Park US-1135 is easily accessed from this exit.

To get a little bit of elevation I drove through the park to the vista point parking area. However the crags themselves are not visible from here, you need to hike out a trail for another 1/4 mile to catch a view of them.

I wasnโ€™t in the mood to carry my radio kit to the viewing area and since both my traveling companion and myself were a bit under the weather, I went for an expedited setup on the nearest picnic table.

Being relatively close to the highway still, I had adequate cell service so the Garmin InReach was just used as a real time clock while I logged 10 QSOs split between 15m and 20m.

Again, once the 10 contact minimum was achieved, I went QRT and we get back on the road for the final several hours drive back to home in San Francisco. I hope to get back to Washington later this summer with a better possibility of picking up a POTA activation while there.

The MFJ Transition

Most of the ham world has seen the MFJ shuttering domestic production announcement: https://mailchi.mp/62e24f2ccc99/a-heavy-sad-heart Some backstory about MFJ: https://mfjenterprises.com/pages/the-story-of-mfj-enterprises-inc Martin F.

Dimwits & Dullards

By: Jeff KE9V
28 April 2024 at 23:00

The most ignorant ham radio speculation proffered online and on the air last week was the suggestion that the loss of MFJ advertising revenue will be the final nail in the coffin for QST magazine. This constant cheering for the ARRL to fail from a too vocal cadre of ill-bred licensees is a nasty shit stain on the entire amateur service. I canโ€™t believe anyone needs a federal license to communicate with such dimwits and dullardsโ€ฆ

Activating and Visiting

By: WB3GCK
28 April 2024 at 18:14

I drove over to Norristown Farm State Park (US-4363, KFF-4363) for a quick activation. The bands werenโ€™t very โ€œQRP-friendly,โ€ but I made the required 10 contacts plus another half-dozen for good measure.

I went with my usual setup: TR-35 (5 watts, CW) and my 12-foot loaded whip. After getting things setup, I tuned around the 40M band and heard Greg WA3GM booming in. Greg was operating from a POTA gathering at Evansburg State Park (US-1351). Since we were only about five miles apart, it was an easy park-to-park contact.ย

After making 13 contacts on 40M, I moved up to 30M. My only QSO there was with W3WJ who was operating from Tyler State Park (US-1430, KFF-1430) about 20 miles away (as the crow flies). Our signals werenโ€™t very strong, but we completed the park-to-park contact.ย 

I finished up with 16 contacts, three of which were park-to-park. I made all but one of them on 40M.ย 

Since I wasnโ€™t too far away, I stopped by Evansburg State Park on my way home. The POTA gathering, sponsored by the Pottstown Area Amateur Radio Club (PAARC), was easy to find. The plethora of antennas was a dead giveaway. There were quite a few local hams there, and a good time was being had by all. After saying hello to WA3GM, KB3SBC, and a few others, I continued on my way home.ย

Weโ€™re finally getting some warm weather here in southeastern Pennsylvania, so it was a nice morning to be out in the parks.ย

My First GitHub Pull Request; Datasette Windows and Spatialite

ย I made my first ever pull request on GitHub this morning!

The gang and I still mostly develop code on Windows boxes. It has more to do with the machines we have available to us on any given day than anything else. (The just-sit-down-and-type machine in our house is also for playing video games, so... Windows.)

This has led to issues when using our Datasette enabled QSO logger and mapping applications.ย 


Datasette on Windows has an issue with finding the SpatiaLite DLL file. The gang and I worked through the issues and documented our really clunky, blunt force, fix. The fix, however, amounted to changing the source code of Datasette itself on a per installation basis. That meant that if I moved to a new Windows machine I had to find the fix and re-implement it. Even worse, that meant that if I wanted to try something that worked only in a newer version of Datasette, I also had to reimplement the fix.

That... Was a Lot.

So, I was totally psyched when I got a little bit of time yesterday to crank out a fix that should work with the existing install and be able to move forward with it. Towards that end though, I need to get my fix added to the Datasette project if at all possible, and that's where the pull request came in. Itย  turned out to be far easier than I might have thought.ย 

First, I forked the datasette repo and moved changes to my clone of the new fork.ย 

I'm a big Simon Wilisonย  fan as well as a big agile development fan as well as a big Datasette fan so I already knew I'd need test cases to keep from breaking existing code. (Also, I work in silicon functional verification, so, yeah,ย  test cases are good.)


The next step was to review the documentation for how to contribute to Datasette. I'd forgotten the documentation step. Sure, I'd documented my fix in the original issue, but did I also need to update the Datasette documentation? I decided I needed to add a small comment about using Spatialite with Datasette for Windows there. I modeled my documentation add after the similar subject on Django.ย 

Then, I made my pull request using the github site. The process was simple. And then, the pull request action for the Datsette repo kicked off automated checks of my pull request! So cool! So far,ย  so good!




Things I Learned: Adding new DLL locations to Windows via the PATH Envrionment Variable

ย This is a note for myself for later when I try to construct a better set of instructions for adding Spatialite to Windows for use with Datasette.


You can instruct Windows to look for DLLs in a new directory simply by adding that directory to your PATH envrionment variable viaย 


set PATH=C:\path to your dll;%PATH%

Many thanks to Christian (IX1CKN) who shares the following field report: QRP Fun Despite the Conditions! by Christian (IX1CKN) The weekend passed without rain, nor snow, but with temperatures that didnโ€™t exactly encourage spending too much time outdoors. It seems that, despite the date, winter has returned. Nevertheless, the POTA call was hard to resist. โ€ฆ Continue reading Christian enjoys memorable QRP DX despite poor band conditions! โ†’

A Soviet Tube in Cuba: The "Little Spider"

28 April 2024 at 10:17


I hope readers have picked up on the discussion of the Islander DSB rig out of Cuba. We had a bit of a breakthrough on this recently. I've been writing about it on the blog:ย 

https://soldersmoke.blogspot.com/2024/04/re-building-islander-dsbcw-rig-in-cuba.htmlย 

One thing I think is especially interesting:ย  The Cubans were using parts taken out of old Soviet TV sets.ย  One of the tubes used in the VFO section of the Islander was known among theย Cubanย hams as "the little spider."ย 

Arnie Coro CO2KK explains why:ย 

"VFO is made with ONE of the 6 "little spider" 5 pentodes... By the way, I am sure you will like to know why the tube is locally known like that... the ZHE letter of the Cyrillic alphabet is something difficult to pronounce to a Cuban - or any other non slavic for the matter - and it resembles like a little spider on the tube's carton and... that's why it is not a 6 "ZHE" 5 but a 6 "little spider" five!!!"

Everyone is an โ€œMFJ Guyโ€: COMMENTARY

28 April 2024 at 06:20

Didnโ€™t see it coming. Iโ€™m sure Iโ€™m not the only one who felt completely blindsided to hear that MFJ Enterprises, a name that is surely known by every ham radio operator, is going out of business. The end of MFJ will also result in the sunset of its subsidiary brands,... Read more ยป

#60m Chad and Easter Isl. worked

ย 


I was up early this morning due to a annoying great tit that knows CW and in continue signing "A" "A". If you think that's funny well....this birds always wakes me up too early except when I need to get up early. Anyway, I decided to see if anything happened on 60m. I knew two DXCC I didn't have on 60m were active there the last few days. And indeed, with very loud signals they were. TT8XX took me only 2 calls before he came back to me. Then I noticed a large pile-up from 5353-5356KHz CW. A quick look at the DX cluster revealed that Easter Isl. 3G0YA was calling. And yes, I received him very well. A few calls later in the pile-up and he responded. 2 new 60m band DXCC in the log.
