    ARLX005 LF-to-LF Transatlantic Amateur Contact is Completed

    Amateur Radio history was made this month when amateurs in Canada
    and the UK completed what appears to be the first two-way
    transatlantic Amateur Radio exchange on 136 kHz. Larry Kayser,
    VA3LK, and Lawrence ''Laurie'' Mayhead, G3AQC, managed the LF feat
    using extremely slow CW that featured 90-second-long dits and
    180-second-long dahs. The two-way contact took two weeks to

    ''We are the first to do a two-way QSO on LF across the North
    Atlantic as far as I am concerned,'' Kayser said. ''We are the ones
    who put the stakes in the ground; others will build on what we have

    The VA3LK-G3AQC contact began February 5 and was completed February
    19 with the reception and confirmation of VA3LK's report by G3AQC.
    Both stations used spectrographic software and computers for
    receiving. The participants agreed in advance to a ''firewall''
    between them for the duration of the contact and that all QSO
    information was exchanged over the LF radio link.

    The UK has an amateur band at 136 kHz. While Canada has not yet
    authorized general Amateur Radio operation on 136 kHz, Kayser and a
    few other Canadian amateurs have received special authorization to
    conduct LF experiments there.

    G3AQC and VA3LK were using a combination of commercial and surplus
    equipment at their respective stations. G3AQC estimated his
    effective radiated power at 350 mW, while VA3LK said he might have
    been at the 5 W ERP level.

    In October 1998, the ARRL petitioned the FCC to create two amateur
    LF allocations at 135.7-137.8 kHz and 160-190 kHz. The FCC has not
    yet acted on the request.
