62nd Midwinter 630m Activity Event Saturday Evening Feb 4-5 UTC

Canadian hams will provide 2-way crossband CW QSOs on Saturday night, transmitting on 630m while receiving on 160, 80, and 40m. US Experimental stations may transmit beacons inside and outside the 630m band. QSL Cards will be sent for 2-way QSOs and for reception reports.

630m signals can be weak and then peak to workable CW levels for short periods, so keep listening. We are all effectively QRP, with Canadians limited to 5W EIRP and US experimental stations in the 5-20W EIRP range. Four 630m stations will be operating crossband in the Vancouver, BC area.

It's possible to receive 630m fairly well using a 160m, 80m, or 40m antenna or a vertical piece of wire as high as you can get it. You can test your reception by listening to Canadian and US stations transmitting WSPR on 475.7 kHz +/- 100 Hz any evening. WSPR signals sound like warbling carrier waves and each transmission lasts 2 minutes. Some end with a CW ID.

630m Activity and CW Crossband Night, Nov 12-13, 2016

For results see postings on http://ve7sl.blogspot.ca/ and http://njdtechnologies.net/category/630-meter-daily-reports/

Six Canadian hams (VO1NA, VE3OT, VE7SL, VE7BDQ, VA7MM, VE7CNF) made crossband CW QSOs, transmitting on 630m and receiving on 160, 80, and 40m. US Experimental stations made QSOs and transmitted beacons on 630m. Maritime Radio Historical Society station KSM was active on 426 kHz.

I enjoy building and experimenting with radio hardware, casual contesting, and DX hunting. I have been a radio amateur since 1977. Until 1984 I operated 40 and 20 meter CW with home-built transmitters from 15 to 700 watts and made use of the university club station VE7UBC. I took a break from radio as I became busy with my career and family. In 2002 I got back on the air with an old Kenwood TS-820S. That was replaced by a new IC-7410 in 2014. I run a home-brew transmitter on 630m.

I am a partner in the construction and operation of the VA7MM 1296 MHz EME station, which has been in operation since 2003. See our web page at http://www3.telus.net/public/va7mm/eme/. We are active during EME contests on CW and JT65.

By profession I am a self-employed electronics engineer and design custom wireless, analog, and microcontroller hardware for industrial applications. See http://www.phasordesign.com/.

Lightwave

VE7SL and I have completed a lightwave QSO between Mayne Island and Cypress Quarry Lookout, a line-of-sight path of 51 km. This was using CW with tones amplitude-modulated on deep red LEDs around 660 nm wavelength.

 

Experiments continue, with hopes to complete QSOs over longer paths and to use digital modes by cloud-bounce.

Midwinter 630m (472 to 479 kHz) Activity Weekend, Feb 6 - 7, 2016

For results see recent postings on http://ve7sl.blogspot.ca/ and http://njdtechnologies.net/category/630-meter-daily-reports/.

Six Canadian hams (VO1NA, VE3OT, VE7SL, VE7BDQ, VA7MM, VE7CNF) made crossband CW QSOs, transmitting on 630m and receiving on 160, 80, and 40m. US Experimental stations made QSOs and transmitted beacons on 630m. Maritime Radio Historical Society station KSM was active on 426 kHz.

I made the following crossband contacts:

     Feb 6, 2016:   KU7Z, W0YSE, VE7KW, VE7BGJ, KG0D/7, W6RKC and locals VE7BDQ, VA7MM.
     Feb 7, 2016:   K7CW, N7BYD, W0YSE, and locals VE7SL, VA7MM.

I also heard maritime station KSM on 426 kHz, and beacons from WD2XSH/20 on 472 and WG2XSV on 476.1. N6SKM and VE7JYH sent reception reports. My QRSS3 beacon was heard by K3ISM. The DX highlights of the weekend were crossband QSOs between VE7SL (Mayne Is., BC) and WA3TTS (Pittsburgh, PA) and NO3M (Saegertown, PA).

   
 

630m Crossband Weekend and Medium Wave Special Event, Nov 14 - 15, 2015

Six Canadian hams (VO1NA, VE7SL, VE7BDQ, VA7MM, VE7CA, VE7CNF) made crossband CW QSOs, transmitting on 630m and receiving on 160, 80, and 40m. US Experimental stations made QSOs and transmitted messages inside and outside the 630m band. Maritime Radio Historical Society station KSM was active on 426 kHz. KYVM on the “S.S. Red Oak Victory” was active on 425 kHz.

I made the following crossband contacts:

Nov 14, 2015     Crossband KK7UV, VA7MM, K6GZ, VA7TA, K6LG, and 2-way 630m with VE7CA
Nov 15, 2015     Crossband K7CW, VE7KW, VE7BDQ, VA7DXX, W0YSE, K9FD/KH6

I also heard beacons from WD2XSH/20, WG2XSV, KSM and heard part of a signal report from California by KYVM, who managed to receive some of us. Mike Tuggle on Oahu, Hawaii received WH2XCR, WD2XSH/20, VE7SL, VE7BDQ, and VE7CNF using a single-MOSFET regenerative receiver and 38ft high inverted-L antenna.

  

Digital Modes on 630m

FSK digital modes that are phase-continuous and of fixed amplitude will work through nonlinear power amplifiers. Such modes include WSPR, JT9, JT65, MFSK8, MFSK16, MFSK32, FM HELL, and RTTY. Some of us (WG2XSV, NU60, VE7BDQ, VA7MM and I) have tried beacon tests on 630m. John VE7BDQ and I have completed 2-way QSOs on 630m using JT9, WSQ, and RTTY.
