3Y0J: SETUP PLANS & FT8 ---> On 7 December Ken, LA7GIA  posted the following
to the Facebook group (https://www.facebook.com/groups/3093983840726129/) of
the 2023 DXpedition to Bouvet.
  Our camp build up plan consists of 4 distinct steps that have been matured
  and developed  during the last 2.5 years,  based on  lessons learned  from
  other DXpeditions.  Lesson 1 is be prepared to go onshore Bouvet  during a
  short WX window.  Thus, if our only chance is going onshore during a 3h WX
  window,  we will bring  our  lightweight equipment  in Step 1.  Step 2  is
  defined as  expanding the station setup with yagis.  Step 3 is bringing on
  the lowband antennas,  and Step 4  is the final step where we complete our
  We have had some feedback on FT8 and the operation. Because we plan to run
  12 stations at peak times, going QRO on FT8 is a question about logistics,
  fuel and risk.
  A lot of amplifier failures on DXped are due to high power and human fail-
  ures.  Thus our setup minimizes this risk by running the 4 FT8 machines as
  much as possible on the yagis, no setting changes allowed by operator. FT8
  operator  can adjust the number of streams,  redirect his call to specific
  continents or adjust the dB level of receiving stations.
  The machines will be running on fixed 100W.  We will start with 2 streams,
  and we might also go single stream. We will monitor our signal reports be-
  fore an adjustment.
  Bringing fuel for amplifiers is also a constraint logistic wise,  all fuel
  has to go into the zodiac and onto the shelf,  please understand that this
  is not a fly in/out DXPed - we're running on generators. We will on Bouvet
  continuously check the available fuel, we have an inline electronic meter-
  ing system. Based on available fuel we can
  (1) increase the heat in the tent (our tent is not heated 24/7!),
  (2) go QRO on CW/SSB,
  (3) go 500W on FT8, two machines max due to power output bottlenecks,
  (4) start the 1000W waffle machine.
  Please note the RF output power levels  are thus initial power levels dur-
  ing start up!  Thus FT8 QRO operation >100W is a question about logistics,
  power rating of the generator circuits  and how to dispatch the load,  but
  also an energy constraint and amount of fuel available.
  Given we can handle the power output  and  energy constraints, we will try
  2x500W on FT8,  that might as well include 160/80m.  However,  our lowband
  ops are likely to be able to man the 160/80 station during the 8h opening,
  only in the case we're not able to man the 160/80m  we will discuss to put
  the FT8 machines on lowband.
  We're not ruling it completely out,  but seeing  the strong team of CW/SSB
  ops this is unlikely to happen, but not impossible.  We have low band  ops
  paying $25,000  to go on this trip for  their lifetime 160m experience.  I
  personally doubt all of them will be sleeping during prime time!

ARRL SCHEDULED MAINTENANCE ---> On  15 December  between 9 and  13 UTC  "the
ARRL HQ network infrastructure  will have  a major upgrade  performed",  Bob
Naumann, W5OV, ARRL Director of Operations has announced. "While not specif-
ically related to LoTW, it is likely that  during this time period,  you may
not be able to reach the  LoTW system  (or any other ARRL system)  until the
upgrade is complete. Please try to avoid this timeframe".

QSL CQ7P ---> The  Portuguese DX Group,  CS5DX (ex CS1GDX)  is receiving QSL
requests for  recent QSOs with  CQ7P.  That was  the callsign used  by  Joao
Rafael, CT1BOP during this year's CQ WW DX SSB Contest,  and the QSLs should
go direct to  Joao Rafael Almeida, Colegio Campo de Flores, Estrada Nacional
10-1, Lazarim, 2829-514 Caparica, Portugal.  Cards already received  by  the
PDXG will be forwarded to him. [TNX CT4NH]

VK5KI ---> Effective 5 December, VK5KI is the new callsign for Tony, VK5AVB,
a resident on Kangaroo Island (OC-139)  who operates mainly SSB.  Originally
granted to VK5GR,  the callsign  was used  from Kangaroo thrice  (July 2020,
January 2021 and July 2022). Charles, M0OXO will continue as the QSL manager
for VK5KI (QSL via https://www.m0oxo.com/oqrs/logsearch.php) [TNX VK5GR]


QSLs  received direct  or  through managers:  3DA0RU,  5R8LH,  5X7W,  7P8RU,
AP2FLY, E20AX/p (AS-107), E51BQ, EP2HAM, GB22HQ, HK0/PY8WW, HZ1HZ,  K7K (NA-
070), OZ5TG, PV8DX, S21SM, V31XX, V85T, VK0MQ, VP8ADR/40, VP8BTR/40,  YJ0CA,
