More info from the CNN website:

The earthquake occurred just after 3 p.m.(2 p.m. ET) the USGS said. Its epicenter was northwest of Le Morne-Rouge, Martinique.

There were some injuries, but no reports of deaths, Nadine Priam, chief editor of Radio Martinique, told CNN.

Roads and homes were damaged and one person was seriously injured after jumping out of a window according to Priam. Several schoolchildren were taken to the main hospital, she said.

The quake was centered just offshore on the island's north side, between the island nations of Martinique and Dominica, Priam said.

The USGS reported its epicenter was about 90 miles below the Earth's surface, meaning shaking at the surface was somewhat muted. Earthquakes centered closer to the Earth's surface produce stronger shaking and generally cause more damage.

Despite the depth, the USGS Web site showed the quake was felt as far north as Road Town, Tortola, in the British Virgin Islands, about 350 miles from Martinique.

Watching Radio

Instead of listening to the radio I've been watching the radio signals.
I tuned into 3730 and 14230 last night and tonight and let MixW do the decoding.
Here are some of the results:

dah-di-dah-dit di-dah-dah

Its all CW this weekend on the bands. CQ WW CW is the thing right now.
I admit that CW is not my favorite mode and I barely listen to that part of the bands.
Still a lot of amateurs use CW and its a great way to communicate, even (or especially) when the conditions are as poor as they are at the moment.
So, this evening I tuned the bands a bit and switched on DM780 from Ham Radio Deluxe to decode the CW.
In that way I still had some fun and heared some nice stations.
I might learn CW in the future... but untill that time keep up the good work all you CW operators!

G5RV or Windom?

Windom AntennaI'm still in doubt about the right choice for a wire antenna.
At the moment I will only use it for SWL, but as soon as I have my license next spring I will use it to transmit as well. With the Novice license I will be allowed to operate on 10, 20 and 40 meter band.

There are a few options for wire antennas, but I want to make a choice between the following two antennas:
- G5RV Center Fed Dipole for 10-160m band - 41 meter long with 450 Okm wire
- Windom Off Center Fed Dipole for 10-80m band - 42m long with balun

I want to ask you all to help me make my choice. So, please let me know your experiences and pros and cons with these or other wire antennas. All comments are welcome!

Een symmetrische antenne zal altijd beter presteren. Het ruisniveau is lager en tijdens zenden is de kans op het veroorzaken van storing (laagfrequent inpraten e.d.) het kleinst.

De Windom, met het voedingspunt op 1/3, is ooit uitgevonden om het voedingspunt dichter bij het huis te hebben (minder coax nodig, makkelijker op te hangen). De nadelen werden voor lief genomen.

Je kan er geluk mee hebben, maar in een dichtbevolkt gebied kan een Windom je veel problemen bezorgen.

Overigens kan een G5RV ook een hoop narigheid geven als je verzuimt een mantelstroomfilter te installeren.

Hi mate.

I've only ever used a fullsize G5RV for portable work. Never had any problems. I use the flexweave material.

JA, 9K, W's, UA9's all made the log when using the G5RV on EU008 last year. Its going to EU092 next year, so you can deduce from that, that i like it!

Never tried a windom, so can't comment

New filters

New CW and SSB Filters in Kenwood R-5000My Kenwood R-5000 receiver had no additional filters in it. When a few stations operate very close to eachother I needed a smaller bandwidth. So after a year of listening on the HF bands I descided to buy some extra filters. I bought a YK-88C CW filter and a YK-88SN SSB filter to put inside my Kenwood R-5000. From now on I can switch between 500 Hz, 1.8 kHz and 2.4 kHz bandwidth instead of only 2.4 kHz.

Website re-designed

The last few days I've been busy re-designing my website. From this moment on the new website is active. The biggest advantage is the direct linking to a specific article. In the past you saw just a part of the website, but now the whole website is shown with that article. A few more small updates will be ready in the next couple of days.
I hope you'll like it ;-)

Direct QSL cards are mailed

Some Green StampsFinally I managed to get some green stamps. Most of the banks doesn't have 1 dollar bills, the smallest was 5 US$. Luckely the GWK at the railway station had them.
I Have been writing quite some cards and enveloppes the last few days and the first bunch of cards is sent across the world yesterday. So, if you're in my log the card is on its way!
I'm looking forward to the return QSL cards!
