OFF AIR but returning after dark on Saturday night

A very different session as K=6 for three consecutive reporting periods makes waves; Trans-Pacific path continues to provide results for West coast stations

– Posted in: 630 Meter Daily Reports, 630 Meters

This session was probably better than we think it was.  Propagation was different and some paths were down, but wild QSB made for an interesting evening.  A late night JT9 session gave a number of stations in Pacific Northwest additional QSO’s and reports(See a transcript from WG2XSV here).  I was not decoding anyone except for WH2XGP and Larry was not hearing me well.  It was just a little over a week ago that the opposite condition occurred and I could not hear him while he was hearing me.  If it were easy and a sure thing all the time, it would get boring so I am OK with not completing the QSO.  If we had tried again two hours later, WSPR reports suggest the QSO would have been easy.  I was tired so it was not happening.

Noise was once again a regional affair.  It was quiet here in North Texas, more so than it has been in a long time but Doug, K4LY / WH2XZO, in the path of the hurricane Hermine, reported a high noise level and impedance mismatch from the rain.  He did his best to operate “receive-only” through the session.

A late G2 storm manifested itself after a session of very strong propagation at the onset of the initial storm conditions.  Multiple reporting periods of K = 6 were observed overnight and while the Bz is currently pointing to the North, solar wind velocities are averaging 635 km/s.  Time to buckle down and ride this out.

This morning’s JT9 session yielded no QSOs and my CW session was noisy but yielded another completed sked at 1030z.  No additional QSOs were attempted or completed.  My overnight WSPR reports were very strong and at CW levels into Minnesota, the Midwest, and Pennsylvania.  Decode totals for this session were down slightly from the previous session, however, but many stations in the East were QRT due to the hurricane.

John, WA3ETD / WG2XKA, was “transmit-only” overnight as improvements to his low noise vertical yesterday resulted in a broken wire which was repaired at first light today so tonight will be the first real test.

Ward, K7PO / WH2XXP, “made it across” again during this session in spite of down conditions, being reported by 36 unique stations including EJTSWL, VK2DDI, VK2XGJ, and VK4YB:

Larry, W7IUV / WH2XGP, was decoded by 27 unique stations including VK4YB and several East coast stations.  He decoded nine WSPR stations using the E-probe again but VK4YB was not one of them during this session:

Steve, VE7SL, reports that he decoded nine WSPR stations and was decoded by fifteen unique stations.  Steve adds that the path to VK was down considerably from the previous session.

Neil, W0YSE/7 / WG2XSV, reports an average night from his location with session DX reported as WG2XIQ, WH2XCR, and WH2XAR.  He provided the following statistics:



JB, VE3EAR, posted the following WSPR statistics from the session on LOWFER:

“Here are the WSPR-2 stations I decoded on 474.200 kHz. overnight:

Rick, W7RNB / WI2XJQ, submitted the following statistics for his session:

Two new receiving stations were observed during this session:  KD4LV and KE0BZE.  KE0BZE was reporting the old frequency of 503.9 kHz.  If he is using rig control or CAT, his receiver was likely on the wrong frequency.  No email address was found on QRZ so if you know him, please direct him to this page for details on correcting the problem so that he might have a chance to successfully  receive transmitting stations.

There were no reports from the trans-Atlantic, trans-African, or trans-Equatorial paths.  UA0SNV was present but Vasily has not filed any reports for the session at this time.

Eden, ZF1EJ, operated two receivers and two antennas once again and in spite of the “wall of noise” to his North, he successfully decoded stations.  The loop was the clear winner in this session, providing a reasonable null and allowing WH2XGP to be pulled out of the noise:

Jim, W5EST, provides a follow up to a recent discussion entitled, “CROSS-COUNTRY 630M CW AND JT9: INFO FROM PREVIOUS SEASONS“:

“I’ve wondered “What QSOs have 630m stations accomplished on cross-country paths before now?”  Thanks for any such information you e-mail to us for this blog!  Here’s what I’ve learned so far.

Larry W7IUV/WH2XGP:   ‘Eric sent you log info for our 630m QSOs, so I won’t repeat any of those: From July 2014 until the present, WH2XGP has completed 57 two-way 630m QSOs with 12 unique US experimental stations. Of those 57, only 12 were CW, the rest JT9.’

For some others of WH2XGP’s more notable log entries, see the Table here:

Date        Local Time  Station       Mode      Reports

22 Feb 2016  0507z  WH2XCR      JT9    S -15  R -14

28 Oct 2015  0246z  WH2XZO      JT9    S -24  R -27

25 Jan 2015   0530z  WG2XNI       CW   S 449  R N/A

14 Jan  2015  0428z  WD2XSH/12 CW   S 559  R N/A

14 Nov 2014  0216z  WG2XKA     JT9   S -23   R- N/A

Larry continues: ‘It is very difficult to make a CW QSO over distances more than 300 miles or so unless you have good stations, good operators, and outstanding conditions at both ends of the path. Note that it is very difficult to get people to turn off their beacons and actually try for a QSO. I hope this will change if/when we get amateur authorization.

TS-590S is RX/TX for all WH2XGP WSPR/JT/CW work on 630 m.  Homebrew 400 watt linear amp yields an estimated 5-10 watts ERP depending on what’s going on at the antenna at any given time.  630m TX antenna: 44 foot vertical, top loaded, (note: the loading coil is at the 33′ level not down in the dirt) with 64 radials from 25′ to 70′ in length.  RX antenna(s): various, including but not limited to beverages, BOG’s, Flag, e-probes, and untuned short verticals.’

Eric NO3M/WG2XJM: ‘I have attached a screenshot of my WG2XJM log. Ten (10) QSOs with Larry that I have on record, two (2) CW and eight (8) JT9.  These are all two-way 630m QSOs.  Power on my end generally runs 5-20W ERP, but there may have been a few QSOs with up to 50W ERP or more.

Two more attachments show QSOs with Rudy WD2XSH/20 (N6LF) and Ron WH2XND (NI7J).  There was also a QSO with WH2XND on SSB that is not in the log, which happened either late last year or early this year.

Also, CW crossband QSOs were completed with VE7SL transmitting on 630M running 5W EIRP. RST is that sent to VE7SL. He was QSX on either 80 or 160M.  These are probably the most Amateur-like 2x QSOs in terms of power output on the 630M side (VE7SL), as XGP, XSH/20, and XND were probably over 5W EIRP during any QSOs. RX antenna used to copy VE7SL was either 160M phased beverage array (2x 1000ft, 300 ft broadside, West) or 630M 8-circle array (W / NW).

2014-11-01 0435z 473.0 CW 449

2015-02-15 0603z 473.0 CW 339

2015-02-15 0706z 473.0 CW 559

2015-11-15 0534z 473.0 CW 549

2016-02-06 0348z 473.0 CW 449

My overall QSO breakdown according to the log is more evenly divided, 37 CW QSOs and 39 JT9 QSOs, but I know for a fact there are probably dozens more CW QSOs that never got logged, while all JT9 QSOs should be accounted for.’ “
