It's amazing what you find. I have just purchased a working Lokata 7 radio direction finder and hand held compass. I whacked some batteries into it and the little screen on the front displays digital information, from what I imagine are marine beacons which, since the advent of GPS are probably no longer used.

I will use it as a hand bearing compass but wonder if anyone has one of these devices or if anyone has a manual that I can aquire.

Redefine success"! Blast from the past. Not that I've looked lately, but I think I've still got mine on 'Athene of Lymington' can't look right now 'cos she's sitting on the concrete in Preveza, Greece. Not that I always hit the target, of course, as my crew can attest. The marine stations are long gone, but as far as I know the aero beacons used for aircraft navigation are still broadcasting. You just need to know the frequency, tune the Lokata 7 to it, then swing from side to side and wait for the null, which gives you the bearing I assume you have the plug-in headphones as well.

You obviously need at least three bearings to give a reasonably accurate fix, which may be the problem these days. Anyway, if that doesn't work you can always go back to the cross staff Auzzee , As a retired airline pilot, I can inform you that most of the aero NDB's non directional beacons are being decommissioned as a cost saving measure, since they are no longer necessary for navigation. I would suggest trying to use commercial AM broadcast stations as they are much more powerful and still available.

Just an aside, I have never used an RDF on a sailboat, but understand that they have to be calibrated for the rigging effect. Any advice there? Cheers, gts Originally Posted by Auzzee. Lakota 7 RDF. Gents, I don't know anything about said unit, but as a retired airline pilot of nearly 40 years, I do know something about the use of radio direction finding.

First , you need to tune to the frequency of a radio station LF or AM with a known charted location. As stated in an earlier post, which I just noticed, most of the aero NDB stations have been decommissioned so AM is probably your best choice. Second , you rotate the antenna or the radio, if the antenna is fixed to obtain the NULL weakest signal as that is much more precise than the strongest signal.

There will be two null positions degrees apart so it helps to know the rough direction to the selected station. The null occurs when the antenna is perpendicular to the line of sight to the station. Hope this helps! Lokata 7. I've just sold one of my cruisers and on beavering through the lockers before handing on I found a Lokata 7 which I'd forgotten all about!

Haven't used it for years but it certainly worked when the old maritime beacons were running they're not now and neither are the aircraft ones. I have not tried using AM radio stations as a source but the unit fires up and it looks as though it's just come out of the box which it has as it was still in the original box! The headphones and the instruction manual are still with it so if any 'oldtech' enthusiast is after one of these get in touch!

This Wiki article gives all the guff on these old tech devices. Older posts now, but did you ever come up with a manual for the Lokata 7? I have the same unit and am also looking for a manual!
