Upcoming 630m Crossband Weekend


This coming weekend will see the annual '630m activity event' on Friday and Saturday night.

There will be a lot of activity from both the U.S. experimental stations and from a group of five Canadian amateurs who will be seeking two-way CW 'crossband' contacts.

The five Canadians will be transmitting on 630m CW but listening for answering stations on various HF (QSX) frequencies. Last year's one-night event was a great success ... hopefuly the two-night event this year will lead to even more participation by interested amateurs in both Canada and the U.S.

Unlike Canadian hams, American amateurs does not yet have access to 630m as a ham band but ... there will be a large number of U.S. 'experimental' stations (most of them operated by hams with an experimental licence) beaconing and working each other and seeking your 'heard' reports. The Canadian operation will give interested hams the actual opportunity to make a two-way MF to HF CW contact, via the crossband mode as well as provide the Canadians an opportunity to test their 630m systems.

Here are the details of the five Canadian crossbanders:


Station: VO1NA (Joe) GN37 Torbay, Newfoundland
Time: 2130Z - 0130Z both Friday night (Nov 13-14Z) / Saturday night (Nov
14-15Z)
TX Frequency: 477.7 kHz
RX (QSX) Frequency: 3562 kHz

Station: VE7SL (Steve) CN88 Mayne Island, B.C.
Time: 0200Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 473.0 kHz
RX (QSX) Frequency: 3566 / 7066 kHz

 
Station: VE7BDQ (John) CN89 Delta, B.C.
Time: 0430Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 474.0 kHz
RX (QSX) Frequency: 3536 kHz

Station: VA7MM (Mark) CN89 Coquitlam, B.C.
Time: 0500Z - 0700Z Friday (Nov 14Z)
0400Z - 0800Z Saturday (Nov 15Z)
TX Frequency: 475.0 kHz
RX (QSX) Frequency: 3570 kHz

Station: VE7CNF (Toby) CN89 Burnaby, B.C.
Time: 0300Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 476.0 kHz
RX (QSX) Frequency: 3558 kHz / 7062 kHz


All stations will either call CQ or run "VVV" marker beacons while listening on their respective QSX frequencies. QSX frequencies will be included
in the CQ or marker beacons.


Last year's event saw many nice contacts, some of them from coast-to-coast! I really hope that as many amateurs as possible will have a listen and be able to answer our 'CQ's on the various QSX frequencies. Your participation on one (or both) of the two night's activity would be just great.


I will post a reminder of the event again at the end of the week ... in the meantime, try to see what you can hear on 630m (472-479kHz) and arrange your setup so that you can call us on HF as well.

For a more detailed description of the upcoming event, see the ARRL's announcement here.

630m Crossband Schedule

VO1NA Torbay, Newfoundland
Following up my last blog posting, the weekend of November 14-15 has now been confirmed for the '630m Special Activity Event' . There will be further details coming regarding the various experimental activities and transmissions but the one that holds the most interest for myself is the 'crossband' operation by several Canadian amateurs.

There are now five Canadian amateurs slated to operate over the course of the two-night event (Friday & Saturday) and they will be looking for two-way crossband contacts with amateurs in the U.S. and Canada. Here is the schedule of frequencies and times:


Station: VO1NA (Joe) GN37 Torbay, Newfoundland
Time: 2130Z - 0130Z both Friday night (Nov 13-14Z) / Saturday night (Nov 14-15Z)
TX Frequency: 477.7 kHz
RX (QSX) Frequency: 3562 kHz

Station: VE7SL (Steve) CN88 Mayne Island, B.C.
Time: 0200Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 473.0 kHz
RX (QSX) Frequency: 3566 / 7066 kHz

Station: VE7BDQ (John) CN89 Delta, B.C.
Time: 0430Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 474.0 kHz
RX (QSX) Frequency: 3536 kHz

Station: VA7MM (Mark) CN89 Coquitlam, B.C.
Time: 0500Z - 0700Z Friday (Nov 14Z)
          0400Z - 0800Z Saturday (Nov 15Z)
TX Frequency: 475.0 kHz
RX (QSX) Frequency: 3570 kHz

Station: VE7CNF (Toby) CN89 Burnaby, B.C.
Time: 0300Z - 0700Z both Friday night (Nov 14Z) / Saturday night (Nov 15Z)
TX Frequency: 476.0 kHz
RX (QSX) Frequency: 3558 kHz / 7062 kHz



These stations will be calling CQ on CW at regular intervals throughout the evening, and listening for answers on the allocated HF call-back (QSX) frequency. The sequence that I will be using (and others in a similar fashion) is:

"CQ CQ CQ de VE7SL VE7SL VE7SL QSX 3566 and 7066kHz K". After listening for callers on either QSX frequency for approximately 30 seconds, the CQ will be repeated if no callers are heard.

With good conditions, propagation can often span the continent, so please consider taking part in the activity from wherever you might be located in North America. Last year, crossband contacts were made between here and W3 / W5 and many points in between.

For eastern stations, VO1NA, in Newfoundland, should be a tantalizing target with coverage throughout the eastern states while the four VE7 stations should prove workable for central and western North American amateurs.

Those that might wonder about the 'legality' of crossband contacts need not worry. Canadian amateurs have had legal access to 630m for almost two years now and crossband contacts with any stations in the amateur radio service are the same as a two-way QSO on any other band. Unfortunately, amateurs are not allowed to contact any of the experimentally-licenced stations ... they are permitted to work each other only.

Hopefully you will print out the operating schedule and consider participating in the November crossband activity weekend ... the more the merrier! It would be great to see even more contacts than last year, which was a great start, considering the less than optimum conditions. I will post more details as the event weekend draws closer. We hope to see you there!

Another 630m Crossband Weekend

Fritz Raab (W1FR), the ARRL's 600m Experiment Coordinator, has indicated that this year's '630m Special Operating Event' will be held on the weekend of November 13 / 14. Mark your calendars if you plan to participate as it looks as though, once again, along with the numerous U.S. experimental stations beaconing and coastal maritime stations, several Canadian 630m stations will be active and looking for realtime CW 'crossband' contacts! Canadian stations will 'CQ' on specific frequencies and will listen for calling stations on designated HF (80/40m) answering (QRSS) frequencies.

Unlike last year, the Canadian stations will be operating for several hours on both nights, since there will be no conflict with the ARRL's CW Sweepstakes Contest as in 2014. Please stay tuned as there will be further details to follow regarding specific stations, frequencies and times ... notifications will be published on both the ARRL and RAC web 'news' pages as well as on numerous ham radio reflectors.

There's still lots of time to tweak up your 630m receiving capabilities ... it should be an interesting weekend, especially if the mid-November propagation cooperates.

A summary of last year's Friday night crossband activity can be found here.

Army-Navy Crossband


Yesterday's mail brought an official - looking envelope from the U.S. Army! It contained a very nice letter from Fort Huachuca, Arizona, thanking me for participating in the '66th Military-Amateur Crossband Test' as well as three QSL's for the Army-affiliated contacts that I had made back in May.


During the activity, I was able to work Army stations AAZ (AZ), WAR (Pentagon), WUG-2 (TN) ... all on 20m via the crossband mode as the military stations transmitted outside of the band.





In addition to these three, two Navy stations were worked ... NWVC (IN) and NPD (TN) but it appears that 'Army' has beaten 'Navy' ... at least when it comes to QSL'ing!

Armed Forces Crossband Opportunities

This coming weekend offers amateurs the opportunity to work many of the Armed Forces stations via the crossband mode. The 65th Armed Forces Day Crossband Communications Test will see stations such as NMC (Alameda, CA), NOJ (Kodiak, AK), NRV (Guam), NMN (Portsmouth, VA), WAR (Pentagon, Washington, DC), along with seventeen others, joining the 24 hour event. Activity will begin as early as May 09 at 0700Z from NRV in Guam, while others will join the fray beginning at 1200Z.

Each station has a slightly different operating schedule and full details of operating times and crossband frequencies can be downloaded from here.

In addition to the usual SSB / CW modes, this year will see several digital modes such as MT63, AMTOR FEC, as well as two new modes ... MIL-STD and ALE.

The needed MIL-STD (Serial PSK) software can be downloaded for free from MS-DMT software.

The activity gives hams and SWL's the chance to exercise their technical and operating skills. All stations will provide a special QSL for contacts made or for reports of reception.

Join the fun and gather some unique wallpaper at the same time ... not many hams have a QSL from 'WAR' on the wall!

630m Crossband Tonight!



Just a reminder about the 630m crossband activity night this evening. There have been two updates to the plan. VE7SL will start one hour later than originally planned and John, VE7BDQ, will be listening on both 160m and 80m QSX frequencies for callers.

The frequencies will be:
  • VE7SL TX 473.00KHz QSX (listening) 1808KHz (160m) and 3535KHz (80m)
  • VE7BDQ TX 474.00KHz QSX (listening) 1813KHz (160m) and 3532KHz (80m)
John will operate from 0200Z (1800 PST) - 0700Z (2300 PST) while I will start one hour later. Both stations will call several CQs at the top of each hour segment, at full eirp,  and listen for any callers on the specified calling frequencies.




The last time this was done, transcontinental contacts were completed ... hopefully conditions will continue to co-operate and propagation will be good tonight.

630m Crossband Activity Night

630m to HF Crossband
Since getting the new 630m band (472-479KHz) here in Canada, one of my favorite ways of promoting interest in the new band has been 'crossband' activity ... that is, transmitting on 630m while the other stations transmit on a predetermined HF (QSX) frequency, usually on 80 or 160m. There are many amateurs in the U.S. who are interested in getting the band as well as many Canadians that are interested in getting on the band and the crossband activity usually generates a lot of interest. Both myself and John, VE7BDQ, have enjoyed making several crossband contacts this past winter and will once again be soliciting crossbanders this coming Saturday evening.

Our plan is to operate from 0200Z through 0700Z, (1800-2300 PST Saturday). Beginning at the top of the hour, we will both be calling CQ on CW and listening for any callers on HF. CQ's will continue until there are no more callers and will begin again at the next top of hour time slot. This should allow for a wide variation in propagation and the possibility of eastern contacts as the evening progresses.

The frequencies will be:
  •  VE7SL TX 473.00KHz QSX (listening) 1808KHz (160m) and 3535KHz (80m)
  • VE7BDQ TX 474.00KHz QSX (listening) 1813KHz (160m)
It is hoped that as many stations as possible will give a listen for us and be able to call on one of the HF QSX frequencies. Both John and myself will be running at the maximum allowable eirp for the duration of the activity.

If you have not had a look for any 630m stations, hopefully you will take the opportunity this coming Saturday night ... you really do not need any special antennas for receiving on 630m. Many of the stations that I have worked on crossband have been using HF dipoles for low-noise reception.

I'll be promoting this event on several of the reflectors and groups that I regularly enjoy and I also invite you to pass the word on to others. Please watch the blog for further updates.

See you Saturday I hope!
