The Sundance Mountain Radio Association (Palmer Lake, CO) today announced the creation of the Things On The Air (TOTA) program. The radio association’s Need More Lists Committee spent the past year analyzing the effect of various “on the air” programs, including the Islands On The Air (IOTA), National Parks On The Air (NPOTA) and Summits On The Air (SOTA).

The overall trend is clear. The ham radio community used to be satisfied with the basic DXCC list (a list of countries that aren’t really countries so we have to call them entities). But over time, additional lists to be worked have been created. For example, the Islands On The Air (IOTA) was created in 1964. More recently, the Summits On The Air program was established in 2002. It seems that every year or so we hear of another “something” on the air program. Even the normally docile satellite grid chasers created a Walmart Parking Lots On The Air (WMPLOTA) event.

Unfortunately, this has created a miss-mash of programs with inconsistent and conflicting rules. The Need More Lists Committee concluded that the best solution to this problem is to fast-forward to the likely end state: pretty much everything can be put on the air. Inspired by the latest technical hype called Internet Of Things (IoT), the committee named this program Things On The Air (TOTA).

To be comprehensive and inclusive, the TOTA program is based on the existing Maidenhead Grid system. There are 324 fields defined (AA through RR), each having 100 squares (although they really are not square). Each square contains 576 subsquares indicated by aa through xx. So using the six-character locator results in 324 x 100 x 576 = 18,662,400 unique locators. Or, as the Committee likes to say, about 18 million locators. In North America, the six-character locator represents a rectangle about 3 miles by 4 miles. This raises the question of how many things need to be on the list inside a typical 3 x 4 mile rectangle. An in-depth study revealed there are a lot of things that might need to be listed in even a small area.

For TOTA to achieve the vision of being the “last list of things on the air”, it must accommodate an unlimited number of listed things. To start out a 15-digit serial number is appended to the 6-character locator to indicate a TOTA thing. As the program grows and new Things are added to the list, the 15-digit number can be extended indefinitely.

Here’s an example listing of some of the first TOTA designators:

Locator  Serial Number      Description
DM79nb   000000000000001    Walmart Parking Lot
DM79nb   000000000000002    Home Depot Parking Lot
DM79nc   000000000000001    Leroy's home QTH
DM79nc   000000000000002    Leroy's barn
DM79nc   000000000000003    The big tree behind Leroy's house
DM79db   000000000000001    Charlie's home QTH
DM78lu   000000000000001    Pikes Peak Summit
DN70di   000000000000001    Rocky Mountain National Park

When making a valid TOTA contact, the activating station must give a signal report and the TOTA designator: 6-character locator followed by the serial number (at least 15 digits but may be longer). The official TOTA list is currently be maintained on an Excel spreadsheet on Leroy’s computer but a HDFS database is under construction to handle the expected large dataset.

The Committee requests the help of all amateur around the world to submit additional entries into the TOTA list. Eventually, this process will be automated via the ThingsOnTheAir.com web site but for now submissions can be made in the comments field below.

YEK - 329kHz courtesy: www.ve3gop.com/

This coming weekend will see another monthly CLE challenge. This time the hunting grounds will be 320.0 - 334.9 kHz.

 

For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.

 


A nice challenge in this one is to hear the Arviat NDB, located in Nunavut on the western shores of Hudson Bay. 

'YEK', on 329 kHz runs 500W into a 100' vertical and it's well-heard throughout North America and many parts of Europe under the right conditions. Listen for its upper-sideband CW identifier (with your receiver in the CW mode) on 329.421 kHz.

Propagation has been very good on the MF band recently but at this time of the year, good listening is often hampered by a lot of lightning activity. Hopefully that will not be the case this coming weekend but today's map shows what we may be up against!

If you are interested in building a system for the new (U.S.) 630m band, the CLE will give you the chance to test out your MF receiving capabilities and compare against what others in your area might be hearing.

When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. Listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are modulated with a 1020 Hz tone approximately.

For example, 'AA' near Fargo, ND, transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz. Its USB tone is actually 1025 Hz while its LSB tone is 1054 Hz.

Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

Canadian NDBs normally have an USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

From CLE organizer Brian Keyte, G3SIA, comes the details:

Hello all

Our next Co-ordinated Listening Event is less than a week away.
It is an ideal one for new listeners as well as for regulars:

Days: Friday 25 May - Monday 28 May
Times: Start and End at midday, your LOCAL time
Range: 320.0 - 334.9 kHz

It's straightforward - just log the NDBs that you can identify having their
nominal frequencies in the range, plus any UNIDs that you come across
there. We last concentrated on these frequencies during CLE216 in
February 2017.

We'll be near the DGPS beacons range and some of us, especially in North
America, may hear a few, but please don't report them in this CLE.

If you are interested in some remote listening - maybe due to local difficulties - you could use any one remote receiver for your loggings, stating its location and with the owner’s permission if required. A remote listener may NOT also use another receiver, local or remote, to make further loggings for the same CLE.

Here is this week’s space weather and geophysical report, issued 2018 May 21 0042 UTC.

Highlights of Solar and Geomagnetic Activity 14 – 20 May 2018

Solar activity was very low throughout the period and no events were reported. No Earth-directed CMEs were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 14-17 May with moderate levels observed on 18-20 May.

Geomagnetic field activity was quiet to unsettled on 17 May due to the influence of a negative polarity coronal hole/high speed stream. Quiet conditions were observed throughout the remainder of the period.

Forecast of Solar and Geomagnetic Activity 21 May – 16 June 2018

Solar activity is expected to be very low throughout the period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach very high levels on 05-07 Jun with high levels expected on 02-04 and 08-13 Jun. Moderate flux levels are expected for the remainder of the outlook period.

Geomagnetic field activity is expected to reach G2 (Moderate) geomagnetic storm levels on 02 Jun and G1 (Minor) storm levels are expected on 01 Jun due to the influence of a recurrent, negative polarity coronal hole/high speed stream. Active conditions are expected on 23 May and 03-05 Jun.
