Subject: Re: [ultralightdx] Logging Your First Ultralight TA or TP
Gary and Mark C,
Gary, That was an excellent discussion of logging your first TP....
Mark's was excellent, as well, addressing the TAs.
Would you two mind if I copied your messages, made them into a
reference PDF and put it on dxer.ca under the title "Logging Your First
Trans-Atlantic or Trans-Pacific Station on an Ultralight???
I might add at the bottom that another way is to do the mod to attach
an external antenna directly to the Ultralight... that can really help,

There are very few experiences in the AM-DX hobby more thrilling
than logging your first TA or TP on an Ultralight radio. As the fall
DX season approaches, propagation will slowly improve to make
transoceanic stations stronger and stronger. Already there is much
anticipation and discussion in our Ultralightdx group about how to make
these thrilling catches.
Obviously, those lucky DXers living near ocean beaches will have
the best chances of logging TA's or TP's on Ultralights, but there are
certain general guidelines that will increase your odds, no matter
where you live.
1) Familiarize yourself with the strongest-signal TA (or TP) stations
and their frequencies. Mark Connelly posted an excellent list of the 18 strongest TA possibilities in a message to Richard Allen on August
27th, complete with extra information on other TA possibilities. To
Mark's outstanding advice, I would submit the following list of great
TP possibilities, all of which have been received on a stock ULR here
on the west coast:
594 JOAK Tokyo, Japan (300 KW)
693 JOAB Tokyo, Japan (500 KW)
747 JOIB Sapporo, Japan (500 KW)
774 JOUB Akita, Japan (500 KW)
828 JOBB Osaka, Japan (300 KW)
972 HLCA Dangjin, S. Korea (1500 KW)
1566 HLAZ Jeju, S. Korea 0 (250 KW)
1575 VOA Ban Rasom, Thailand (1000 KW)
Of these, the strongest bets are usually JOAK-594, JOIB-747 and
JOUB-774. Choose a few possibilities from this list, according to your
local QRM situation. The stations in S. Korea and Thailand are more
challenging than the Japanese stations, but are very possible on stock
2) If you are chasing TA's, you will need to listen around sunset,
and if chasing TP's, you will need to lose some sleep like the rest of
us by listening around sunrise. (Note: If you actually end up logging
TP's, the loss of sleep is easier to tolerate).
3) Use an SSB-equipped "spotting receiver" to check the signal level
of the transoceanic stations you are attempting to log. Place the SSB receiver (E1, ICF-2010, ICF-SW7600GR etc.) in either USB or LSB mode,
and dial in the transoceanic station's frequency. Then offset the dial
about 500 Hz, and check the strength of the heterodyne (whistling
sound) to see if the station is strong, weak or non-existent. If you
can hear audio on the station's actual frequency (on the SSB receiver
in LSB or USB mode), then your Ultralight has a fighting chance to log
the TA or TP.
4) Ultralights are always stuck in the AM mode. For this reason,
they have trouble hearing TA's or TP's=2
0only 1 or 2 kHz away from strong
domestic stations. If the TA or TP's frequency ends in a 3, 4 or 5,
your chances are better than if the transoceanic frequency ends in a 1
5) If you live in an east coast or west coast state and can drive to
the ocean coast for a DXing session, you will increase your chances of
success immeasurably (as long as it is reasonably isolated, without
many local stations). Salt water can make almost any Ultralight
perform like a champion.
6) Hot-rodded Ultralights need hot-rodded SSB spotting receivers.
These Ultralights (with 7.5" or larger loopsticks) can easily exceed
stock SSB receivers in sensitivity. The new E100 Slider
Loopstick-equipped models will outperform any stock SSB receiver,
making it necessary to use something more sensitive (table receiver
with external antennas, or SSB portable with huge loopstick) for best
7) Experienced DXers will go out of their way to help you-- feel free
to ask questions about languages, programming, ID's, etc.
8) Have fun! Receiving 3 TP's on a stock SRF-59 is what hooked me on
the Ultralight concept. Be psychologically prepared for a similar
transformation in AM-DXing excitement! :>)
