2017 July 2
Numbers today SN:11 SFI:71 A:11 K:2. Not a single DX spot on any band except a 5 dB spot from WZ7I on 20! Not a beep in ZL any band from here.
2017 July 1
Good numbers SN:11 SFI:72 A:4 K:2 but not a single Rev Beacon Spot on 20m in the morning from North America. VK9AA is readable on 14200.
2017 June 16
Last couple of days I’ve found that VOA CAP doesn’t predict propagation to ZL very well in the evenings. At my sunset +/- one hour the best band is 40m. The prediction says -21dBs/-6dBs for SP/LP. For 20m the prediction is +27dBs/+15 dBs for SP/LP but there is no propagation over SP at all and good propagation over LP.
Later when trying the 18 MHz LP opening to ZL I got better spots from US East Coast when beaming over SA than when beaming NA. Propagation to ZL was poor.
SN28, SFI77, A4 k4.

Today I found out that I had a good signal into ZL, North Island on 20m one hour before my SS when beaming 150 dgs. That’s 90 dgs off SP or LP. Nothing when beaming either SP or LP!
Later found same phenomenon on 40m but not as pronounced as on 20m. There is a signal getting through over SP/LP but with QSB and weaker than over the 150 dgs path. Or possibly it’s just steeper take off angle on 40 so the rotary dipole workes even when pointing in the direction of the propagation path.
Same is true for 30m.
2017 May 15
Last couple of days the morning SP to ZL on 20 has had a twist to the North. With best signal due North.
2017 May 13
Very good openings to KH6 in the mornings on 20m.
Best path to ZL on 20m in the morning now is mostly SP. LP at times. VK always best over LP.
2017 May 12
Worked ZL3GA on 80 right at his SR.
Today the tubes were delivered to the door and dropped into the linear. Works fine. Same performance as with the old Eimac tubes as far as I can tell.
2017 May 10
RF Parts in California no longer export the tubes so I put an order at TheDXShop in the UK yesterday.
While waiting, the L7 runs nicely with just one tube. Output varies between 700 and 800 Watts depending on band.
I have tried to figure out what has caused the failing welding of the plate connection. Exactly the same thing happened to the other tube some years ago. I think a probable cause are the very tiny movements the plate makes on every dot and dash when sending telegraphy. A rough estimate gives a failure after 100 to 200 million dots and dashes.
The brand of the tubes is Eimac.
2017 May 6
The other day there was a bang in my L7. One tube had a warped plate. Not a big deal I thought. Had a spare never used 3-500z in the garage. Plugged it in and started to cook it to improve the vacuum (I thought). But things looked weird. So thought something had broken by the flash over. After hours of troubleshooting there was no alternative but a faulty tube. And yes, the new one had a short between grid an filament. So now running on one 3-500z. Don’t dare to run more than about 700W output (at 1200W input). Till I find a new tube.
2017 April 19
After days of super propagation. QSO with ZL3NW on 160m and other nice achievments, things seem to return to normal. Aurora flutter on 40m on signals arriving from ZL. ZL2IN on this recording: QSO at 0615 UTC.
And QSO with VK4WTN on 30m at 0635 UTC:
Suddenly in the evening TB was wide open to ZL with Aurora hanging over us. QSO with ZL3NW again. Now with extreme signals. Recording below was on the low TX dipole just to show how good the propagation was:
2017 March 11
Started at 0630z. 80m closed for DX and 40m poor. Went to 30m and QSO with Cliff, ZL4AS at 0716z with 579/579.
2017 March 10
Aurora QSB again. Worked ZL3XDJ on 40m CW at 0709z. Brian was a 559 with aurora QSB. I got 599+5 without QSB. Strange propagation.
Called 9G5X on 160 and 80m CW. Good signals but no QSO.
2017 March 9
Bands have improved but only QRV late on 40.
Worked 9G5X at 2200z. Very good signals.
2017 March 8
Still poor conditions.
Worked OA1F at 0702z and VK2WP at 0708z on 40m CW with weak signals and
8Q7LH on 80m CW at 2147z with aurora flutter.
2017 March 7
Very poor conditions in the morning. 80m closed here but ZLs worked from rest of Europe. Only DX heard on 40m was ZL3XDJ with S3 to S5.
Went to 20m. Silence, but JA8OW answered a CQ. Signal from S1 to S3. He was using 400W and a 3 el tribander. I got a 589 report.
2017 March 6
Worked ZL4TT at 1824z on 80m CW LP. Poor conditions with 339/339.
Found out I was logged as SM0DRF on 30m by VP6EU :-(. Fortunately the 17m QSO was OK as they went QRT just after.
This morning QSOs on 40m CW with Ian, ZL2AIM, Cliff ZL4AS and Drew VK3XU. Drew was using 100W and a dipole. Fair propagation (SSN:11 SFI:73 A:16 K:3).
2017 March 5
VP6EU (Pitcairn) worked on 30m CW at 0837z and on 17m at 1500z. Still poor propagation (SSN:0 SFI:75 A:22 K:3). Very weak and fluttery signals. No S-meter deflection.
Later in the evening worked LU1AJH, PY2CSU and VU2ONR on 40m CW with good signals. So the Aurora is loosing its grip.
2017 March 4
Conditions very poor (SN:36 SFI:78 A:22 K:5). No Rev beacon DX spots on my CQs but QSO with ZL3XDJ/QRP on 40m LP in the morning. Brian was using 10W:
Not a beep from VP6EU during the whole day.
2017 March 3
VP6EU S1-S2 on 40m CW from 0800z to 0830z then going down.
2017 March 2
Poor conditions but Paul,ZL4TT had good signals on 80m LP coming in best on my NW beverage. SN:55 SFI:81 A:36 K:4 after last nights Aurora.
QSO with FK8IK, Mic on 30m CW at 0725z. Mic was a good 579 and only DX on the band.
5Z4/DL2RMC on 30m CW at 1632z
ZL4TT on 80m CW at 1802z.
2017 March 1
QSO with ZL4TT, Paul on 80m CW at his SR at 1809z. He was using 400W and his 43 ft vertical with 2 elevated radials. I was listening on my 185m unterminated SW beverage listening “over my shoulder”. Was TXing on the 2 el inv vee wire Yagi and with 1 kW.
Later QSO on 80m CW with Rob, W1MK at 2220z. All signals had a strong aurora echo when listening on the dipole. Less so with the NW beverage.
2017 Feb 27
Worked JR2UBS on 40m CW at 2204z with 599/599 but with Aurora flutter.
2017 Feb 26
XX9D worked on 17m at 0725z. Also on 15m CW but that was a DUPE :-(. A case of senior moment.
DU7ET worked on 80m CW at 2212z. He was stronger on the Inv L dipole than on the Inv Vee Yagi.
2017 Feb 25
JR6CSY worked on 40 CW at 1612z.
VA2QA worked on 30m CW at 1821z.
CX/N3BNA worked on 30m CW at 2112z.
Today whole 160m from 1810 kHz and up is occupied by SSB contesters.
2017 Feb 24
Last evening XX9D was peaking S8 at times on 160m but no QSO. They seem to have problem with receive. Maybe QRN.
This morning 80m was poor. Went to 40m. Propagation was fair with QSO with ZL2RX, ZL3XDJ, VK3FGE and FK8CE.
Outside -8C blue sky and snow.
ZL1AIX had a very good signal on 80m CW peaking just before 1800z. No QSO.
Worked PY2NN on 40m CW at 2229z with 579/579.
2017 Feb 22
Worked WP4L on 40m CW at 0744z with 559/559.
Nothing heard on 80m this morning.
Worked A31MM in Tonga on 80m CW at 1559z. Not very strong.
2017 Feb 20
Worked Ian ZL2AIM at 0632z on 40m CW. He was S9 with some QSB and I got 579. Recording from just after the QSO:
Bit later at 0655z ZL1DCO, Dave in Auckland in the log for 40m. He was running 10W into a dipole.
At 1611z QSO with Yosi, JA9PPC on 80m CW using the 2 el Yagi. Was receiving beter than the Inv L dipole. 569 both ways.
XX9D in the log for 30m at 1645z. Very weak.
QSO with HS0ZME, Lars SM6NT on 30m at 1650z with 599/599.
2017 Feb 19
QSO with Brian, ZL3XDJ on 30m at 0715z with 599/599.
3XY3D in the log for 30m at 2209z. Was S1 to S3 working NA but came back on first call. Only station heard on whole band!
2017 Feb 18
ARRL contest so fled to 30m.
QSO with Pete ZL2AZ in Wellington on CW at 0724z. He was a good 579 and I got 569.
2017 Feb 17
Worked ED8URT on 80m CW at 2235z. The Inv L Dipole was 1-2 S-unit better than the 2 el Wire beam when that was tuned for NE. When switched to SW, the beam was 1 S-unit better than the inv L. Signal strength around S9 so 6 dBs per S-unit.
WA1BXY worked on 80m CW. He was stronger on the beam tuned for SW than on the inv L dipole!
A Reverse Beacon comparison favours the Inv L Dipole with 2-3 dBs on NA East Coast.
2017 Feb 16
QSO with 9K2NO on 160m at 2049z. He was slightly stronger on the tower than on the dipole but S9 on both.
Tried XX9D on 1823.5 kHz earlier but deep QSB and no QSO.
QSO with Jw2US on 160m at 2117z. Slightly stronger on the tower. Peaking S7, First call.
Listened to W1MK on 80m CW at 2250z and he was at least one S-unit stronger on the 2 el Inv vee Wire beam tuned for SW than on the Inv L dipole with one leg pointing horizontaly to SW 20m up and the other leg almost vertical. Very strange.
QSO with A5A on 80m CW at 2317z, Was much better on the Inv L dipole. S8-9. First call.
2017 Feb 15
Worked XX9D on 40m CW at 1504z and on 80m CW at 1530z, 10 minutes before my SS. That was on the 2 el wire beam since I thought he was stronger on that antenna on receive but still very weak at 1520z. But when checked again after QSO he was S6 on the beam and S7 on the inv L dipole.
2017 Feb 14
Worked XX9D on 15m at 0647.
80m looks poor. Very weak spots from Europe and low from NA.
ZL3NB heard with 449 at 1715z on 3511. Going down. No QSO.
2017 Feb 13
Called XX9D on 80 and 40 for two hours and no QSO.
At 1756z a new contact on 80m with Yosi JA9PPC with 569 both ways. He seemed to be 1 S-unit stronger on the wire beam than on the inv L dipole but when asking him he said both were equal.
80m in the morning didn’t produce any DX despite fair Rev Beacon spots from NA. Worked ZL2AIM on 40m at 0708z. I was weak with him, up to 559 but he was peaking 589. Bit later worked ZL3XDJ at 0742z. He was about 569 here while I was peaking 599 plus 10 dBs. So very strange propagation.
2017 Feb 12
Worked Yosi JA9PPC on 80m at 1804z. He was markebly stronger on the wire beam than on the Inv L dipole unlike JA7BXS yesterday.
TL8TT was worked on 20m CW, 20m SSB, 17m CW, 17m SSB and 15m CW during the day and 40m CW in the evening. Higher bands were closed.
2017 Feb 11
Heard LU and NA stations with reasonable signals in the morning but no contact. Seems as my best time is well before SR.
Worked VK3XU on 40m CW at 0735z and TL8TT on 15m SSB at 1035z.
VK3IO on 80m at 1801z on the wire beam.
JA7BXS on 80 at 2114z. 5-10 dBs better on the Inv L dipole than on the Wire beam (as usual)! Ham CAP proposes 20 dgs take off (6 dgs at 5 MHz).
2017 Feb 10
This morning NY2PO was very loud on 80m, 45 minutes after our SR. S9 on the meter and I received 569. He was about 10 dBs stronger on my inv vee 2 el Yagi pointing to the SW than on my inverted L dipole with one leg horizontal at 20m and one leg vertical. Normally it is the other way around.
When comparing 80m Reverse Beacon spots from SM4OTI he had an extreme signal strength in a very short peak on the NA East coast right at his SR. This is at VE3EID:
Worked JA9PPC on 80m CW in the afternoon and later VK2BJ.
