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

Current Operating Frequency and Mode

OFF AIR for storms, probably for much of the week if the forecast holds

Average propagation for April but high noise from central US storms; Good daytime activity in the West; New carrier on 475 kHz heard over broad area

– Posted in: 630 Meter Daily Reports, 630 Meters

The details for April 26, 2016 can be viewed here.

It was a noisy session from storms here in the central US.  Propagation around North America was average at best and seemed to deteriorate as the session progressed but that may have been the result of increasing noise levels by morning.

Geomagnetic conditions have remained at elevated-quiet levels though the session.  The Bz continues to point slightly to the South but solar wind velocities continue to decrease, currently averaging near 495 km/s.  DST values remain at negative levels but have improved slightly over the previous session.




There were no trans-Atlantic openings reported during this session.

Phil, VE3CIQ, reported that he decoded four WSPR stations and he was decoded by nine unique stations while at 50-watts TPO.

Neil, W0YSE/7 / WG2XSV, reported that he decoded five WSPR stations and he was decoded by twenty unique stations at approximately two-watts EIRP.  Neil indicates that the West coast had a lot of listeners during this session.  Neil also added that daytime activity in the western portions of North America was quite good and he offered this capture that was gathered after 2200z:

Dave, N4DB, reported that he decoded seven WSPR stations on a night where a number of stations were QRT for poor weather conditions.

Hideo, JH3XCU, posted links to two tables showing VK -> total JA DX  and VK -> JA peak S/N for the session.

Roger, VK4YB, reported “Heavy static from storms in the Tasman sea. Should be much better tomorrow. Propagation down on last night. Still plenty of reports from the PNW.”  Roger received reports from JA3TVF, VE7BDQ, VE7CA, W7IUV, WH2XCR, WI2XBQ, and WI2XJQ.  He provided reports for WH2XCR and WH2XXP.

Larry, W7IUV /  WH2XGP, provided reports for five WSPR stations and he received reports from 32 unique stations including ZL2AFP.  As W7IUV, Larry provided reports for six WSPR stations including VK4YB.  Larry notes that propagation was poor and activity was low.

Ward, K7PO / WH2XXP, received reports from 44 unique stations including VK4YB and ZL2AFP.

There is a new carrier that seems to be heard across the East near 475 kHz.  Its audibly strong and appears to be originating out of the East from my stations here in Texas and does not appear to be modulated, true ‘N0N’.  Dave, N4DB, noted that he was also hearing it in addition to an adjacent CW beacon but the strength and location of the carrier made copy difficult.  Have a listen and lets seem if we can figure out the origin of the original carrier if it is on the air tonight and coming days.

After a few days off-air it was nice to be QRV again even if only running WSPR.  The band was average at best and storms in Oklahoma made listening tough until I switched to one of the receive loops.  My transmission totals were normal and those report details can be viewed here.  My reception report details were down (report details can be viewed here) but that is typical when using directional receive antennas and is one reason that I prefer to listen omnidirectionally when I can so everyone gets a fair chance.  This is a complication for the central US since there are two coasts that demand attention.  Its very rare that I don’t hear WH2XCR but I QRT’ed early for big storms moving into my area which may account for the missed report.  There is a possibility that I may have a CW sked tonight but that is dependent on a number of factors.

Eden, ZF1EJ, provided reports for three WSPR stations and he was reported by eleven unique stations including WH2XCR.

Laurence, KL7L / WE2XPQ, was transmitting again and received a few brief reports from the western North American station as absorption continues to be high.  He shared two-way reports with WH2XCR and those details are included in Merv’s report details below.

Merv, K9FD/KH6 / WH2XCR, reported VK3HP who has been absent for some time and he shared two-way reports with VK4YB.  Merv also provided reports for ZF1EJ and shared two-way reports with WE2XPQ.  Merv received reports from VK2XGJ and ZL2AFP.  Coverage in North America was generally limited to western stations and openings were either down or QRN was the limiting factor.  JA paths were once again cut off.  DX report details can be viewed here.  Update:  I originally listed VK4ZAV but it was a phantom report.  Thanks to Roger, VK4YB, for letting me know!
