All frequencies are keyed from Londonderry. This might seem like a unusual setup but it is used extensively in the Armed forces.
Also for your information, we use a TT-273 Transmitter Distributor with standard teletype tape. The signal then goes through a CV-2015A (Teletype to Morse Converter). This converter is made by the Wiltec Corporation of Wilbut, Connecticut. The output is Direct Current keying which may travel via microwave, tropo., or landline; or any combination of these to
the above listed locations. Using the ISB mode of transmission on the above
frequencies, also have the capability to key 75 baud radioteletype when the requirement exists.
I hope the above information will be of use to you in your DXing efforts. I have enclosed a QSL card for the frequency you reported and look forward to hearing from you in the future. We will send QSL's for any frequency for which we are responsible.
