VE7SL RADIO NOTEBOOK



Working Crossband - MF To HF


Attention Amateurs in North America !


If you are able to receive 630m CW signals, I and several other VE7 stations would very much like to have a QSO with you via the CROSSBAND mode - with my station transmitting on 630m (on CW), and with your station transmitting on HF CW (160, 80 or 40m).

For amateurs in the central states to the east coast, Mitch, VE3OT, has also expressed his enthusiasm for working crossband stations and would love to hear from you. His very capable station is well heard throughout the eastern half of North America and has been worked on CW from here as well.

Mitch can be reached at: ve3ot.mp(at)gmail.com

'Crossband' contacts should be possible with stations across much of western / central North America on normal nights, while on good nights, transcontinental QSO's may be possible.

A completed QSO demonstrates that a similar QSO could also take place, entirely on 630m, should all U.S. amateurs be given access to these bands. Every crossband contact that goes into the log provides additional proof that U.S. amateurs really do want full-time access to this band and are willing to put some effort into making this a reality. As well, all two-way work further demonstrates that amateur activity on this band does not interfere with commercial interests (Hydro) and other primary users, nor them with us. Your activity is important and appreciated!


CROSSBAND QSO PROCEDURES - MF To HF


To be logged as a valid QSO, BOTH stations must receive the following information:

    1. RECEPTION OF BOTH CALLS

    2. RECEPTION OF YOUR SIGNAL REPORT

    3. CONFIRMATION ('R') OF RECEIPT OF YOUR SIGNAL REPORT BY THE OTHER STATION


In other words, a normal CW contact!

I will soon be adding a gallery of QSL cards showing who has been worked via the crossband mode on 630m. Hopefully these contacts can soon all be made on 630m!


LF Log / Activity Report



Although this page has been updated as of March 2017, I have left the following 'archival' activity report describing my station activities during Canada's '2200m Experimental Program' to indicate the propagation possibilities that 2200m can support.

U.S. amateurs are also in line to receive the 2200m 'ham band' sometime soon!

JULY, 2004 - Initial testing of the LF station (~ 95W) was followed by a two-way QSO on 2200m with Scott, VE7TIL, in Vancouver. Although the distance was not great, it was the first two-way 2200m work from Western Canada, the nearest other Canadian activity being in Ontario. This contact took place on July 11, 2004.

The first few nights of beaconing turned up several encouraging screen captures. The first was received from Steve, AA7U, in Elgin, Oregon. Steve's report indicated that the system was indeed working, actually far better than I had anticipated. Mitch Powell, VE3OT, vacationing in Alberta, also sent some similar captures, indicating that the 95 watt signal was making it over the Rocky mountains! Steve's capture is shown below:

OREGON SIGNAL

OCTOBER, 2004 - My first crossband QSO was with John, VE7BDQ, located in Tsawwassen, B.C. John was using a homebrew converter for receiving on LF, while transmitting on 80m CW. John's receive antenna was a large coil and tuning capacitor located outside in the backyard! He now has a new homebrew 8' loop antenna for LF work.

VE7BDQ QSL

DECEMBER, 2004 - In late November, extensive antenna renovations were completed to the 3-wire flatop when the antenna was lengthened and raised much higher. As well, the new 500W transmitter was completed and ready to go. The first overnight test on December 4th and 5th resulted in several encouraging signal reports as well as a new crossband QSO with Roger, KØMVJ, near Duluth, MN (EN36vt).

KØMVJ QSL

Roger initially reported that my QRSS30 signals were very strong and that I should go to QRSS10. He then reported that the QRSS10 signal was 'easy copy' and that I should speed up to QRSS3. It turned out that QRSS3 was a little too weak so I went back to QRSS10. The capture below shows the difference between the two speeds.

KØMVJ CAPTURE

Bryce, KIØLE, also in Minnesota was watching that night and sent along a screen capture of my signal report to Roger. The capture below shows my "5NN 5 73 TU" transmission. I stopped sending the second "599" when Roger called on 80m CW with a string of 'R's indicating he had received his RST report OK.

KIØLE CAPTURE

That same night and the following night, screen captures were received from Jay, W1VD, in Burlington, Connecticut (FN31ms). Jay reported seeing the signal all night and even past his sunrise. Here is his midnight screen capture of my QRSS30 signal at ~ 2500 miles distance.

W1VD CAPTURE

Again on both nights, Mitch, VE3OT near London Ontario (EN93ja), reported copy 'all night long', with signals peaking shortly before dawn. Mitch provided this predawn capture.

VE3OT CAPTURE

DECEMBER 19, 2004 - VY1JA in Whitehorse, YT, indicated that he was ready to look for LF signals with SPECTRAN, an FT-990 and his 40m wire antenna. After running the beacon for a short time, Jay was able to report good copy so a two-way crossband QSO was scheduled and completed later that evening. Jay was transmitting on 80m CW and listening on 137kHz to my QRSS3 signal.

VY1JA QSL

VY1JA CAPTURE

After our crossband QSO, I let the LF beacon run all night at 50 watts output. Jay reported that the 50W signal was also good copy in Whitehorse.

VY1JA 50W CAPTURE

Jay is in CP20kw, approximately 1000 miles to the north. He now has an experimental licence for 136kHz and will be building a transmitter this winter. Hopefully an 'all LF' QSO with Jay is not too far away!

DECEMBER 20, 2004 - A fine two-way crossband QSO was completed with Dan, W7OIL, in southern Washington (CN85pu). Dan indicated that the signal was strong on Argo and that he could hear the signal as well.

W7OIL QSL

W7OIL CAPTURE

DECEMBER 27, 2004 - Another overnight beacon session resulted in several reports from Alaska (KL1X near Anchorage) to eastern USA.

Steve, W3EEE in Maryland (FM19qj), monitored all night and sent this pre-dawn capture from 2350 miles away.

W3EEE CAPTURE

Dex, W4DEX in North Carolina (EM95tg) at 2360 miles, monitored with one leg of his 160m dipole!

W4DEX CAPTURE

Not to be outdone by his neighbor (W3EEE) Lloyd, W3NF, also in Maryland (FM19mh), sent proof of his reception.

W3NF CAPTURE

W1VD in CT again reported hearing the beacon, indicating best reception from 0515 EST until sunrise fadeout.

W1VD CAPTURE

DECEMBER 28, 2004 - Lewis, WA4LIP in Lucedale, Mississippi (EM50vq) at 2175 miles, reported reception using his 40' x 40' NW-SE loop and IC-706/preamp.

WA4LIP CAPTURE

JANUARY 15-16th, 2005   weekend was highlighted by three crossband QSO's with stations in the Vancouver-Victoria area. Borge, VE7VB in Victoria, a long-time LF experimenter, used his 50m longwire to receive on LF, along with a beautiful old McKay 3001A receiver. VE7WU, Allan in Victoria, called the next day after configuring his 40m Delta loop and Icom 775 for LF receive. Ralph, VE7XF in Tsawwassen, combined his 160m inverted L and FT-1000MP for LF receiving. It was great to see the effort put forth by these amateurs -- obviously there is much interest in 2200m developments here on the west coast!

VE7VB QSL

VE7WU QSL

VE7XF QSL


JANUARY 29, 2005 - A regular CW to CW crossband QSO was completed on Saturday night with VY1JA near Whitehorse, Yukon.  Jay was on 80m CW while I transmitted on 137kHz CW at around 10 wpm. Jay reported exceptional signal levels on QRSS60 and suggested we attempt the two way CW crossband QSO which took about 9 minutes to complete. Hopefully the next QSO with VY1JA will be on 2200m.

DECEMBER 31, 2005 - A nice crossband DX QSO was completed with Andy Flowers, KØSM in Lincoln, Nebraska (EN1Ørt). Andy was transmitting on 80m CW while using his low band dipole for receiving on 2200m. Thanks for your enthusiasm Andy!

KØSM QSL


If you would like to attempt a two-way crossband contact, please let me know ...I would love to give it a try!
