When you hook up the SRS FS700 to the antenna you can monitor the front
panel
LORAN output with a spectrum analyzer and determine what has to be
notched out
either in a separate multicoupler with high and low tunable notches like
the Austron 2084
or the notch filters ( greater tuning range) built into the FS700.
My internet search a few days ago shows Loop Head in Ireland was never
built/commissioned.

Good Morning Claude,
I am assembling a K9AY terminated loop antenna, pointing to N. Europe.
(~30 degrees)
Will use a ARR preamplifier at the antenna.
I hope to start listening later this month.
Some stations to listen for:
Lessay, France master on GRI 6731, Soustons France, slave X
BO , master on 7001, Jan Mayen, slave X, Berlevag slave Y
Sylt, on 7499, Lessay, slave X, Vaerlandet, slave Y
Eidi (Ejde) on 9007 master, Jan Mayen slave W, BO slave X,
Vaerlandet slave Y
From my location on Cape Cod FN41sr, looks like the closest active
chain is Eidi with GRI of 9007
Eidi, IP62lh DX of 2900.1 miles
Jan Mayen, IQ50pv, 2900.2 miles
Lessay, IN99fd at 3274.1 miles
Soustons, IN93hr at 3412.4 miles, (6731 GRI)
I have not calculated BO, and Berlevag details (7001 GRI) nor for the
Sylt chain.
A google search on "Loran C stations" will show a listing of the few
active stations
with the station details like RF power output and Lat/Long.
I have converted Lat/Long to 6 digit grid locator for my ease in LOB and
DX calculations with BD2004 software.
Sky wave propagation should be possible for the North Atlantic, European,
Western Russia, Saudi, and Mediterranean chains.
Low likelihood of any ground wave and its better accuracies.
I miss my Nantucket Loran-C station and its Cs accuracies.
A modern Stanford Research Systems model FS700 Loran C receiver
is on hand as the receiver.

Thats odd it says loop head Ireland not exactly the middle of the ocean. At
least thats the closest station I can find.
But that said I can get a frequency measurement but also at my very limit
from what I can tell.
I do want to look at the autron 2000 and SRS FS700. The 2000 lets you see
things more easily and the SRS may have a better front end. Hard to say.
I really have a local noise source thats causing trouble and not sure how I
will find it.
