 For you CW buffs out there, a great group is the CWops. This is an international organization and their main goal is to promote continual improvement of CW proficiency across a broad range of activities. They have a CW academy which moves people along toward improving their CW skill level. They have a monthly newsletter (which can be found on their site) called Solid Copy which is all things CW. 

 Have ever been on the air and all of a sudden a section of the CW band becomes alive with action? Most likely if it's a Wednesday or Thursday it's the Weekly running of the CWops Tests or as it's also known as CWT. This is a mini 1-hour contest. Everyone is welcome in these mini contests, and it's a great way to improve your CW skills. 

Today was the first time I took a dive into the CWT. The hours went by very fast and in this contest I was in Search and Pounce mode and not Running. I made 14 contacts for 196 points, not a record by any means. But I was getting my feet wet. 

I encourage you to have a look at the CWops site and for sure have a look at their newsletter Solid Copy.

I previously wrote about some of the tools I use for managing SOTA and POTA logs. See Tips and Tools for Managing Logs. I continue to learn about the file formats and various tricks for generating the logs. Some of this is not well-documented…at least I haven’t found it…so I am sharing what I’ve figured out. My apologies in advance if I get any of this wrong. Reader Beware!

Lately, I’ve been trying to figure out how to do one log file for both SOTA and POTA. I am not aware of a logging program that will handle both simultaneously. (Let me know if you do.)  The ADIF file format can handle this and is the way to go for such a log file. Also, an ADIF file can be imported into other logging programs and Logbook of The World. The complete documentation for ADIF can be found here: https://www.adif.org/

SOTA Logs

Our combination SOTA + POTA activations usually start out as a SOTA activation. Then, if the SOTA summit is inside a POTA-designated park, we may try to do both simultaneously.

The SOTA database supports uploading ADIF files, including support for Summit-to-Summit (S2S) contacts. The figure below shows a recent SOTA log, in ADIF format, displayed by ADIFMaster. The 6th column is MY_SOTA_REF, which is the SOTA reference for the summit I was activating. In this case, it was W0C/SP-084 and is the same for all of the QSOs. The 9th column is SOTA_REF, which is the SOTA reference of the other station’s summit, if any. Most of the rows are blank, because the other station was not on a summit. However, N0TZW and N3ALT were on W0C/PR-031 that day resulting in a pair of S2S contacts. If you get these fields set correctly in the ADIF file, the SOTA database will log the activation and the S2S contacts correctly.

POTA Logs

For simple POTA activations, you just need to get the QSO information correct and the file name indicates the park you were operating from. For example, the file name K0NR-K-4404-20211017.adi indicates the station callsign (K0NR), operating from park K-4404 on 17 Oct 2021. The POTA system will try to identify Park-to-Park (P2P) radio contacts in the file, by comparing activator logs. My understanding is that this works only for the simple case of two activators, each operating from only one park.

The figure below shows a POTA log using ADIFMaster. The 7th column is MY_SIG_INFO, which is the POTA designator (K-8295) for the park I was activating. This is the same for all of the rows. The eleventh column is SIG_INFO, which is the POTA designator for the other station. Most of these are blank because the other station was not in a park. However, there are six QSOs shown that were Park-to-Park. Note that the QSO with N7OOS was entered twice, with two different park numbers. This is because he was doing a double activation that day…putting two parks on the air at the same time. Yes, activating multiple parks at once is possible, even common, in POTA. A good example is when a national scenic trail runs through a national forest. One operating location is in both parks simultaneously.

It might be possible to have two POTA designators tagged to one QSO, I am not sure. But I think it is cleaner to just enter it as two separate QSOs. I know the POTA database will interpret it correctly. When I imported the file into Logbook of The World, it complained there were duplicate QSOs, which were easily ignored.

The 6th column in the figure is MY_SIG, which indicates a special interest activity or event (e.g., POTA). In the general case, the logging program would use this field to interpret the meaning of SIG_INFO and MY_SIG_INFO. It appears that the POTA system does not require MY_SIG to be set to POTA and will just go ahead and interpret SIG_INFO and MY_SIG_INFO for POTA use. Not shown is another field called SIG, which is the special interest activity or event of the other station.

Creating a SOTA/POTA Log

When doing a combination activation, I’ll set up the logging program for SOTA or POTA based on whether I expect to have more S2S or P2P radio contacts. For example, if I just expect to work a few summits and many parks, I’ll use HAMRS with the POTA template. That way, all of the parks get entered correctly from the start. I will note any S2S contacts in the comment field and come back later to fix them.

The easiest way to manage ADIF files is via ADIF Master. You can also edit the files manually using a basic text editor but that can be error-prone. To add a new field in ADIF Master, you insert a new column (right-click on a column, then left-click insert column). Then create a label for the column by right-clicking the top of the column, followed by Custom, entering the name of the new ADIF field.

Here’s the short list of ADIF fields that may need to be used:

MY_SOTA_REF is your SOTA reference, the summit you are activating

SOTA_REF is the SOTA reference for the other station, assuming its an S2S radio contact. If you submitting a Chaser log, this is the SOTA reference for the summit you are chasing. Your MY_SOTA_REF would be left blank.

SIG is the name of the contacted station’s special activity or interest group (e.g., POTA)

MY_SIG is your special interest activity or event (e.g., POTA)

MY_SIG_INFO is your park number that is being activated.

SIG_INFO is the park number for the park you are working (P2P).

By editing my log files using ADIFMaster, I’ve been able to create log files that can be submitted to SOTA, POTA and LoTW without errors. It takes a little bit of work to get the file right. Before you submit a log file, it is always a good idea to view it using ADIFMaster, to try and spot any obvious errors. This is especially useful for POTA logs, when the turnaround time can take up to two weeks.

This is what I’ve learned. How about you?

I must have driven past these fells hundreds of times and have always had a want to activate them . Not because they are big or impressive. Some tiddlers just happen to be as much fun as the big ones. Not many contacts but it was windy and getting colder as the day wore on. Here’s the route, you’ll see that my watch went a bit mad at the summit of Sale Fell.Maybe the RF isn’t good for it

Stuart/KB1HQS has been experimenting with various modifications of the Arrow II antennas. Recently, he put together a video of the various mods, well done and interesting:

Ultimate Arrow Antenna Modifications

I am a big fan of the Arrow II style antennas for VHF SOTA. Initially, I used the dualband 2m/70cm antenna for satellite work as well as mountaintop activity. This started before SOTA was even a thing, as I hiked in the Colorado mountains and made radio contacts just for fun. These days, we normally carry the 2m-only version of the antenna, with split boom and 3 elements. My personal seamstress (Joyce/K0JJW) worked up a really nice rollup case for it. Sometimes, we’ll take along a separate 5-element 70 cm Yagi, which can remain fully-assembled and strapped onto my pack.

All antennas are a compromise between cost, size, weight, performance, convenience and durability. I have found that the 3-element Yagi from Arrow fits my needs really well. I have not been motivated to modify it. The Arrow antenna has a gain of about 6 dBd and is 37.5 inches long. We handhold the antenna and that is about as big/long as I’d like to hold. I am still in search of a higher-gain antenna for those special situations when I know that a few more dB of gain could make a difference. I’ve not really found anything I like. A longer boom would likely require a mast and, therefore, a guy system, which adds more weight and complexity.

Antennas are a never-ending source of options and experimentation, so go out and try something new.

From the RAIN HamCast episode #57, 2021-XII-25 (used with permission):

RAIN’s Hap Holly/KC9RP spoke with Tomas recently about Solar Cycle 25. This is the second and final excerpt from their discussion.

From the introduction to The RAIN HamCast, Episode #57:

In this episode, we continue our discussion with Tomas Hood/NW7US, the author of many writings about space weather and effects of solar activity the past 20-plus years.

(Part 1 of 2 can be found here: Episode #56, https://www.youtube.com/watch?v=HnuSOXhFELQ)

Tomas has been a short wave enthusiast since 1973, a ham operator since 1990, and is a United States Army Signal Corps veteran today. He launched the first civilian space weather propagation website, HFRadio.org, in the mid 90’s; HFradio later spawned SunSpotWatch.com; at press time Sunspotwatch.com is being revamped for the new Solar Cycle 25.

Tomas has contributed to the Space Weather Propagation column in CQ magazine for over 20 years, and for The Spectrum Monitor magazine since 2014. A product of the Pacific northwest, Tomas resides now in Fayetteville, Ohio.

 Well here we are again.......finishing off my second year in the Maritimes. It may sound a bit odd, but it seems it has taken just over a year and a half to get used to retirement. I am finally starting to settle into somewhat of a routine. It's been another year of COVID, but I am singing to the choir with this one as we are all well aware of this. Julie and I are fully vaccinated and bootered up and up to this point have managed to avoid COVID.
