Bouvet Island Dxpedition – are u ready? 3y0z

Bouvet Island Dxpedition kicks off late January

Thee Yankee Zero Zulu…   listening up…

It is the most isolated spot in the whole world – a fact which anyone who cares to spend an instructive five minutes with a pair of dividers and a good globe can easily verify. Around Bouvet Island, it is possible to draw a circle of one thousand miles radius (having an area of 3,146,000 square miles, or very nearly that of Europe) which contains no other land whatever. No other point of land on the earth’s surface has this peculiarity.

It’s also #2 on the DXCC most wanted list.     Come join us as we bust the pileup and work 3Y0Z from the K9IU ham shack !

Sure to bring out the best of DXers world wide (and a few kids, lids, and slims too)

whats unique?


It’s a rare one   Last  activation was back in 2008 .

Also the timing of the expedition is a bit unusual – we are at sunspot minimum- these guys are spending big bucks to do a Dxpedition with the sun isn’t spotting     -probably a bucket list thing.  No time like now –  just the same they’re gonna have fun and make lots and lots of QSO’s !

We of course wish them fair winds and safe travels, and especially good propagation !!

Repeater Mapping Online – Hypothetical Radio Coverage Maps

With all the work on the K9IU repeaters, a few of us got curious about coverage and some what-if’s with respect to antenna gain, height above terrain, power output and more.  Check out this cool program for repeater mapping – free and web based:

Here is a sample of the coverage of the K9IU VHF repeater according to the computer.  Coverage is actually a bit better than what the computer depicts.   Interesting none the less.

As a reminder, K9IU is hosting analog and digital repeaters which provide traditional analog VHF FM,  as well as C4FM System Fusion (VHF),  D-Star Digital (VHF and UHF) and DMR (UHF) repeaters.

Please consider to join K9IU – dues are just $20/year and all funds go to expand the club’s radio room / ham shack equipment and repeater system.  We hope to raise enough funds to keep improving our repeaters and do some experimenting, adding back an IRLP/Echolink node and cross linking the digital – analog systems.

D-Star VHF K9IU Repeater back on air – now @ 146.940 Mhz

We completed maintenance today to get the K9IU VHF D-Star Repeater back online.     It’s currently up and running in local mode until the node controller (a raspberry pi) is configured.

Note the D-Star list is in need of update, for Bloomington we have the 146.940/(146.340 input) VHF repeater and the 444.900/(449.900 input) D-STAR on UHF.

IMPORTANT: Don’t forget to change your D-star repeater config in your radio accordingly, the list from Icom/D-Star Info is incorrect and outdated.

The UHF D-Star repeater is also on air but in local mode for now.   Also awaiting the raspberry Pi node configuration.

Reflector 024 should be back soon !  The trick?  A 20 year old windows xp notebook –  driver works !

Thanks to Matt KB9YOJ  and Corey KB9JHU for help getting us back on air !
