12/13 November 2016. ANNUAL FALL 630m ACTIVITY NIGHT: coordinated
by Steve VE7SL. Scheduled operation: QRV 12 Nov 2130-13 Nov 0130utc.
TX 477.7 QSX 5362. Several other Canadian stations will be on.
A loose connection in the B+ meant a delay of 5 mins until QRV on the air.
QRV 2135 (6:05 NST) running 50 watts to the big RL. 6 QSOs including
one 2xCW on 630m with PE5T. Remainder were crossband, listening on 80.
The PE5T Q was the is first TA from this station since the 630 was
authorised to all Canadian amateurs in 2014. Frank VO1HP worked PE5T
by listening on 475.2 and transmiting on 3562. In the log:
vo1aka n1bug pe5t vo1di vo1hp and w3lpl with reports ranging from 519 to
599. Also heard the YWA ndb on 517, wg2xka on 472 and wg2xiq on 474.

shows good reception 2200-0100 with Roelof reporting audible sigs.
25th. QRSS3 clear on DF2JP streamer and aural reception again at PA0RDT. 26-27 A=48 K=5. Nil at DF2JP: Joe
sends a magnetogram showing a strong dip in the field. Poor reception
at PA0RDT although better than a NDB in NS when the QRN subsided in the
morning. Local reports VO1DI solid, VO1LM (27th, 429) VO1UL and VO1VCE nil.
27-28. Roelof notes a slight improvment in sigs but QRN is preventing
aural reception. 519 at VO1AKA. 28-29. Conditions remain depressed. QRT for a while.
01 June PA0RDT reports stronger sigs from VO than I. TX on again 2208 utc
20 watts to the big RL.

4-5 March. PA0RDT gets another fine copy.
And a very clear aural reception And if the first one doesn't get through, try them all at once. Markus does a remarkable superimposition.
He writes: " ...carrier trace was quite narrow so conditions were stable again last night. Weak sidelines at +- 4.16 Hz corresponding to the dot rate were als o visible. Unlike Roelof, I have no chance of actually hearing your CW message here. So I made an attempt to bring it out of the noise using coherent averaging =2E The saved data files from 23 to 6 UT were assembled into one large arra y. Then the phase evolution of the AM carrier was estimated and used for sy nchroneous demodulation (just like in opds). Thus the modulation appears in the in-phase baseband component, allowing coherent averaging of multiple m essage repeats. From the sidelines I knew the dot duration, but I had to use trial and er ror to find the message length. In the end, a cycle of 208 dotlengths (25.0 0228 s) and 1126 averages turned up an easily readable fast-CW decode, show n in the attached screenshot (black =3D in-phase, cyan =3D quadrature). "
6-7th. Poor reception at DF2JP of the 10 WPM CW. The DST had taken a 100 point dip. 7-8 CW 10 WPM 40 watts to the 100m RL at 18m. VO1UL reports weak sigs.
The minmiwhip (VLF-HF E field antenna) celebrates its 10th birthday. It was designed by Roelof who used his miniwhip in a hawthorn tree to show how reception of CW signals on 477.7 kHz varied over the past week. TNX to VE3OT for some bits used to assemble the MW. -- 27,28 mar. 30 watts to the rl. 27th fair copy by pa0rdt. 29th better copy. 30th.

Sked request from G0MRF and good excuse to check out the 630m stuff. First the tower wouldn't accept RF. Evidently the 100m rotated L (15m average H) was mucking up its impedance. Tried the RL with a few dozen 3" turns of 2 mm insulated wire. Min SWR (under 1.5:1) and 0.75 amps at 20 watts. Set back power supply variac to give 10 watts. 12 WPM sigs were received in Markland QRB 68 km. Crank up the variac for QSO attempt with G0MRF/p 50 watts to a 100m rotated L at 15m average height. No QSO but traces of signals received both ways. WA3ETD reported reception on this side of the pond at 0154. NL reception of Joe's callsign transmitted by Dave And overseas, Dave recieves his callsign transmitted from here

MRCN Experimental Proposal
The purpose of this study is, in part, to gather information for the Canadian delegation in support of an allocation for the amateur service at the WRC2012. This was made an agenda item by the IARU. The large area of the province and the need for reliable emergency communications makes this study of considerable regional importance. The IARU has a long history (From "The T. & R. Bulletin" 3,1, July 1927) Copyright of the Radio Society of Great Britain and reproduced here with their kind permission.

2 December 2013. An announcement is made on the Evening NL Net on 3740 kHz concerning the operation on 14-15 December. VO1VZ, VO1YR, and VO1UL have expressed interest in participating. It is hoped to get as many amateurs as possible to copy the message and send it to their municipal representatives. This operation is to focus attention on the proposed new band and the value of amateur radio in emergency communications. It is dedicated to the memories of Dr Ken Pulfer, VE3PU who worked at the WRC2012 to secure the new band, to Wayne Smith VO1TA who provided signal reports, and to Dave Colton VO1TK a member of MRCN.

Jul/Aug 2011. The power is reduced from 100 to 35 watts to reduce the voltage on the tower. The beacon signal is a CW ID at 8 WPM followed by a 10 second carrier.
May 2011. Jim VO1YR has noted night time QSB of up to 30 dB. Carl VO1UL has copied the beacon at 0050 utc but not during the day. On the 11th, Jim measured the signal levels from the 21m vertical and the 100m horizontal. The latter was 7 dB down. VO1UL hears the beacon on the 21m tower but only after dark. Last night 0113 utc (12 May) and 0054 (13th) on HF beam pointing SW. 80m antenna was too noisy.
25 April 2011. Experimented with tuning a 21 metre tower on 507.77 kHz: 267 uH of inductance was required for resonance. A 100m wire was used for an antenna. The transmitter power was 100 watts. Mode: 8 WPM CW beacon followed by 10 seconds of unmodulated carrier. 2140 UTC: signal reports were received from VO1YR (Shoal Harbour) r=100 km 559, VO1TA (Hearts Delight) r=50 km 589, and VO1UL (St Anthony) r=500km who was unable to hear it until about 2320 because of strong power line interference. Carl used an HF beam instead of a G5RV because the former had a better S/N. Thank-you gentlemen. 26 Apr. Wayne reports 58/99 VO1SJH reports nil. VO1VCE: 53/59 Carl: no report. Tried loading 21 m tower, but got high SWR. Using 100m wire. 27: 0130 UTC. -57 dB (rel) at VO1YR using 80m dipole. 1820 utc. Using 21 m tower for TX. VO1JA (Harold in Garnish,r=200km 255 degrees) reports 559 sigs on 80m dipole. Ken VO1KVT (Lewisport 235 km 317 deg)) Nil. VO1NC( New Chelsea) Signal strength 2.
According to information from inquiries by Jim Dean, although standard amateur contact are not sanctioned by an international treaty, we are evidently permitted to acknowledge foreign stations who call us.

November 2009. A report is sent to RAC. In an unfortunate turn of events, RAC is advised by IC that there may be no provisions for Canadian 500 kHz experimental stations to communicate with other stations. Not withstanding that communication between amateur and other experimental stations was explicitly included in the officially approved experimental proposal, for the purpose of "exchanging signal reports and comparing propagation" further communications from VX9MRC are henceforth voluntarily suspended pending further information.
09 December 2009: 2200-2300 UTC and 10 December 0100-1000 utc CW 507.77 kHz. Reports will be posted at a later date.
