Hi all, I've been thinking about attending a ham show this year. Who among the LF crowd expects to be coming to Dayton? To Friedrichshafen? Thanks and 73, Stewart KK7KA
Hi all, I've been dreaming about a system tentatively named MARS (Multi Antenna Reception System). The basic concept is very simple. LF signals are simultaneously captured at several stations in the
Hi Pat, This is interesting stuff! Alan, G3NYK and I have had many discussions over the past few years along the lines of a transmitting equivalent of this idea. The basic premise is that it should b
Hi Jim and all, I guess for an initial feasibility study it would only be necessary for a number of stations to simultaneously make recordings under defined conditions, and then the data could be up-
Hi Mal, Since RJ45 is commonly used for Ethernet, you should be able to find the F/F adapter at most shops that sell or install computer network equipement. If not, try the guys who do business phone
Hi John and all, Is the cave TX using a loop (wire or earth)? If so, I would expect the cave signal to be mostly magnetic, so an electric LORAN antenna, e.g. 1 m whip, would pick up little cave signa
Hi Alan and all, However in practice the capacity of the antenna continues to increase at about 5 to 6 pF per metre. This turns out to have two useful effects. First is reduces the size of the loadin
Hi Stewart, The USCG spec for LORAN requires that at least 99% of the radiated energy be contained within the 90 to 110 kHz band. Assuming that limits for the 250 kW station at Rugby are the same, th
Hi Alan and all, You should be able to easily split this, either with a PDF tool, or with a zip program. If you don't have Acrobat or a print-to-PDF utility installed, take at look at http://sourcefo
Hi Mike, I know nothing about the TS-850, but almost all radios have a trimmer capacitor or other adjustment for the main reference oscillator. If you set that properly, the slope of your tuning erro
Well, some other folks who have been separated by contract for 9 years next week seem to agree with us Yankees. In Chinese, floors are counted the same as in the US: (one-floor) is at ground level,
