NEWS UPDATE – Mark arrived yesterday and according to N0UN (recording below) he will remain on Socorro island for the next 5 weeks. He’s running 300w and a 140′ off center fed wire at 60′ with no QRM on the island.


FEBRUARY 27 – According to entry for 4B4B, the dates of the expedition are now for the entire month of March.

DECEMBER 12, 2017 – Mark, XE1B will be active as 4B4B from Socorro Island, Revillagigedo Islands, NA-030 between March 1-15, 2018. QRV on 160-6m; SSB. QSL via XE1B direct, Club Log OQRS.


  1. It will be hard to work. One operator, only SSB. Americans will make a huge Pile Up.
    For EU queue is too long.

    Good luck!

  2. Frank,
    Careful with Marcos XE1B, he use to keep for himself the money which is intended for sending the QSL cards.
    Also usually he end up stealing equipment from his colleagues during DXpeditions, in fact he has been kicked out from several DXpeditions in the past. Let’s see how he’s going to behave this time.
    In Mexico he’s the shame of the HAM community.

  3. Here is to Dan XE1FSK,
    What a coincidence ! as far as we know you were the one kicked out from his very dxpedition XF4MX in March 1999, The dxpedition that XE1B, Mark has conducted as Team leader in March 2011 as 4A4A earned The Mega Dxpedition award by the German DX foundation with an incredible historical record above 73 000 qso’s.
    Also Mark has been awarded in contesting obtaining top first places, and by looking your QRZ page seems that you are quite a coward trying to put down such a dxpedition. You have a big mouth and have no respect for the ham comunity, we are not stupid Dan.


  4. These QSL selling DXPeditions are becoming epidemic lately. Maybe I’m old fashioned but either you finance your DXpedition yourself or raise enough sponsoring, either you stay home.
    Trying to earn money by selling QSL cards is NOT amateur radio. It has NOTHING to do with it.
    Trying to have a free vacation is NOT the idea neither.
    The fact that he will not LOTW proves everyting! (athought there are – God forbid- expeditions that charge you for sending a LOTW confirmation).
    We’re on the wrong track with these clowns!

  5. Just another silly DX’ped to collect money from US/SA/JA/OC/West EU and tease, irritate and piss off East EU and Central AS ! Especially with no command of CW 🙂 ! And all money in one pocket. If 5 USD QSL charge for 10-20 ops big DXped to rare entity can still (but hardly) be acceptable, then there is no way for 1 person to charge the same fee and can be regarded as a coercive sponsored extortion. Fully agree with Bruno, ON6AB that “either you finance your DXpedition yourself or raise enough sponsoring, either you stay home”. Guess it’s time for ARRL DXCC to start disqualifying such “expeditions” for DXCC status

  6. Nobody is forcing any one to pay out any money. If you do not like the qsl cost then do not work him.

    If the op stayed at home as you suggest then you would not have a qso with xf4. If the op is charging too much for a qsl then you will not work him and not have a qso with xf4. Either way, the result is the same, no qso with xf4.

    I will not bother working this one as I only need the LOTW confirmation but I am sure there are many out there needing any xf4 qso and are happy to pay the qsl cost. Why deprive guys of the opportunity by forcing the xf4 op to stay at home.

  7. Too funny, Wayne! This is the second time in a week I’ve been captured in one of your on-air recordings… last week with the “P5” on cw, and now 4B on phone (I work him right after you).

  8. Worked Mark yesterday PM on 20m ssb but can’t be certain he got me in the log due to QSB and QRM. I heard him acknowledge my call but that’s all. I know he doesn’t like dupes, and I don’t blame him, but I have to take a chance again in the days ahead and get this ATNO in my log. Sure would be nice to be able to confirm his log on line in near real time or within a day or so in order to avoid having to attempt a dupe.

  9. Any chance to communicate with him and ask to try work earlier, when band in EU is open?
    Every time he starts, bands are dead here.
