4B4B DXpediton NOTES:

4B4B is now QRT...

UPDATE - Wednesday Feb 28, 2018 18:12 UTC:

According to an update on his page he will now be active the entire month of March...starting tomorrow!

UPDATE - Friday Jan 26 15:59 UTC:
Usually I don't feature solo DXpeditions but this is a rare entity and Mark, XE1B, has put a lot of time and effort into making this one happen!

He will be active as 4B4B from Socorro Island (in the Revillagigedo Islands) on March 1-15, 2018. Socorro Island is IOTA NA-030 and Grid DK48mr.

Revillagigedo was last activated in 2011 and is number 32 on Clublog's "most wanted" DXCC list!

On the 4B4B page, Mark notes that it takes several years to get through all of the paper work and permitting - contributing to the scarcity of this DXCC entity.

As there are no flights to Socorro he will be sailing there on board the Mexican Navy battleship "Manuel Doblado".

Mark will be active using SSB on 160, 80 and 40 meters plus 20 through 6 meters. He is planning on the following frequencies :

1850, 3790, 7065, 7165, 14195, 18140, 21295, 24940, 28475, 50140 KHz

Gear is scheduled to include an Icom IC - 7600 transceiver, an ACOM 1010 amplifier, a Spiderbeam on 20-10m, 4 element yagi on 6m, vertical on 40/80 and a long wire on 160m.

For me this would be an ATNO and I hope I can get Mark in the log - good luck to all of you!

I'll update this page soon - 73 de Randy / WB9LUR
