Plans continue to make certain that all is in readiness for my expeditionary cruise to Antarctica aboard the M/V Enderby in February 2018.
A cruise previously planned to Australia and New Zealand aboard the Holland American Line ‘”Noordam” occurred in late October. During that time I was able to visit with Rodney, the owner of Heritage Expeditions in Christchurch, New Zealand and Rowan Homes who owns Nautic Electronics.
I gave Rowan the MFJ 998RT auto-tuner and he installed it inside of a Fiberglass Reinforced General Purpose enclosure. This and the Pacific Aerials High Frequency SSB Vertical were then mounted on a top deck railing aboard the Enderby.

Another project was to be assured the primary radio set up – the Yaesu FT 897 and SPE 1.3KW amplifier were communicating happily with each other and the MFJ 998RT auto-tuner. This necessitated a ‘road trip’ to Starkville, Mississippi, home of MFJ where Martin Jue, Richard Stubbs, Ben, Mike and others let me set up a temporary station using a vertical antenna and testing everything out. All worked well.
MFJ employees setting up temporary vertical so functional testing of the Yaesu 897, SPE 1.3KW amplifier and MFJ 998RT auto-tuner could be verified. (see pic to the Right)
Bolted onto an aluminum panel with padding underneath are the Yaesu FT-897 and SPE 1.3KW amplier. The amplifier can fly as in-cabin, carry on luggage due to its compact size and 22 pounds weight. The SCS Pactor Modem and West Mountain Radio RigBlaster Blue sit on top of the white Velcro mounting patches.
My visit with Rodney was most enjoyable and informative. This voyage is one that I feel especially fortunate to be going on. I’ll provide more details via the radio email Winlink program during the trip.
If propagation is more favorable in February than it was in October, I should be able to make a large number of contacts especially during Antarctica Activity Week, February 17 to 25, 2018.
As a back up, I will be using an Icom 7100. A problem shared by both the FT 897 and the IC 7100 is a lack of sockets to plug stuff into. Common to both radios is the need to have an SCS PACTOR Modem as part of the complement, and, to have minimal to none cable switching going on.

The FT 897 problem was resolved with a bhi CAT-MATE Electronic “Y” Splitter and a quick jumper move at J102 on the ACC 1/8 inch socket for ALC and PTT control to the SPE amplifier.
The Icom 7100 requires the use of the ACC conversion cable (OPC-599). ACC1 on the “Y” cable accepts a 9090 cable from Farallon Electronics to the SCS PACTOR Modem. The ACC2 socket will take the PNP-7D1 cable to the MFJ Ameritron ARB-704 amplifier-to-transceiver interface. The ARB-704 will output ALC and PTT to the SPE amplifier.
Of course another road trip to Starkville will be necessary to make sure all this works.
Next on the list is an after Christmas shopping trip to the Mall of America in Minneapolis, Minnesota for warm weather gear as per the suggestions of Heritage Expeditions and several other ham friends.
All I want for Christmas is an SFI above 100 for the month of February. I won’t be too dismayed if there is a good to spectacular auroral display sometime before we get to midnight sun conditions.

What else to say? John, congrats for the excellent job. You and your friends are doing really great.
All seems to be well planned, and your Antarctic adventure, I’m sure, will give you lots of satisfactions; we’ll follow you every day.
