Radio: it's not just a hobby, it's a way of life

Current Operating Frequency and Mode

OFF AIR for storms - just one more night - should be QRV Saturday night!

Field day is here and with it the MF and LF demonstration and outreach opportunity; VK4YB 472 kHz CW QSO with ZL1ZLD memorial station; Trans-Pacific paths are generally unchanged from the previous session although path between JA and VK has improved

The details for June 24, 2016 can be viewed here.

IMPORTANT REMINDER: Neither 630-meters nor 2200-meters are open to amateurs in the US yet.  Please continue to be patient and let the FCC finish their processes.  Click here to view the proposed “considerate operators” frequency usage guide for 630-meters under Part-97 rules that was developed with the input of active band users.

Noise conditions were similar to the previous session but primarily concentrated in my “neck of the woods” in the south central US.  By morning, North Texas was at ground zero for  the major weather event which will likely mean that my start in the field day MF and LF demo today will be late.  As I was describing to someone else, that’s OK because these storms have dropped temperatures 30 degrees from yesterday’s highs.  This field day is the first in 30 years where we here have had an on-going rain event in the morning of field day.  Normally we get pop-up storms near dinner or at 3AM.  Hopefully this cooler weather will enhance everyone’s operating experience in this region.

Geomagnetic conditions were moderately more active.  The Kp-index has generally been at elevated-quiet levels.  The Bz is pointing to the South and solar wind velocities are averaging near 360 km/s.  A few periods of elevated protons were observed but those levels were nothing like the previous session.  DST values have trended downward but are not too serious at the moment.  The reports from the prognosticators are that this weekend should have quiet band conditions and good propagation but maybe they mean for the high bands, which can be very different from the low bands.  We will see.




Roger, VK4YB, reported  his first QSO with ZL on 630-meters.  Roger explains:

“It was a fairly typical night until I spotted what looked like a CW signal on the WSPR waterfall. The frequency was 474.929 kHz, near enough to the WSPR band to show up on the console.I immediately reached for the headphones and switched to CW mode on the Elecraft K3. Sure enough it was ZL1ZLD and he was good copy. I called him and he came straight back with a 439 report. You beauty! First ZL QSO on 630m. I gave him 579. Paul told me that I was only the third VK station to be worked on 630m from the Musick Memorial Radio Station, operated by the Musick Point Radio Group. Their first VK QSO had been back on 5 Sept 2013 with good friend, Peter, VK4QC. I am not sure who the other VK station worked is, but it is a long time between trans-Tasman QSOs. Here is a picture of the 630m transmitter in use at ZL1ZLD. Little wonder I was copying at 579!

The station commemorates Pacific Aviation Pioneer, Captain Edwin C Musick and full details of the wonderfully restored station can be found at www.musickpointradio.org

Today is the MF and LF field day demonstration and outreach opportunity.  The following operator details are up to date as of this morning, although I expect my station may be running late due to weather.  I will know more later.  Updates can be viewed here.


Al, K2BLA / WI2XBV, reported that “The low noise and strong sigs of yesterday gone today. Moderate noise and weaker sigs. Decoded only 3 this AM.”  I suspect field day may mean a slow night on WSPR for the next 24-hours.

Larry, W7IUV / WH2XGP, provided reports for two WSPR stations and he received reports from twenty unique stations.  As W7IUV, Larry provided reports for two WSPR stations.

Trans-Pacific report details, excluding KL7 and KH6, can be viewed here.

Hideo, JH3XCU, provided this link detailing VK -> total JA DX and VK -> JA peak S/N for the session.

Roger, VK4YB, reported that “Tonight’s session was very much a repeat of last night, with mild QRN, Ward, WH2XXP was down a little and only reached -20dB right on his sunrise….”  Roger received reports from 7L1RLL4, JA1NQI, JA3TVF, JH3XCU and TNUKJPM.

Ward, K7PO / WH2XXP, received reports from 33 unique stations including ZL2BCG,  VK4YB and VK2XGJ.

Oceania 24-hour WSPR activity


Eden, ZF1EJ, provided reports for three WSPR stations as he continues in a receive-only capacity.

Laurence, KL7L / WE2XPQ, is transmitting CW on 473.5 kHz for field day but his WSPR receiver provided reports for two stations between CW transmissions:

Merv, K9FD/KH6 / WH2XCR, appears to have been in a receive-only capacity, providing reports for VK3HP, VK4YB, VK5FQ, and ZL2BCG.  DX report details can be viewed here.
