The famous old workhorse, the LH Series Little L-Per Direction Finder, is no longer in production or available from the factory. It has been replaced by the LL Series Little L-Per Direction Finder. The change occured when some of its key components became obsolete. The new Lpers incorporate state-of-the-art technology and many of your suggestions for improvements, including ease of operation, more compact, waterproof receiver with no separate parts, easier to read display, and flexibility in frequency selection (no crystals) with the same or better performance as the L-Per you are used to using.
We have also discontinued manufacturing the LA Series Aircraft Direction Finder. The new LL Series Little L-Per DF can be used in aircraft with the LAA Series Antennas mounted on the aircraft (same as used with the LA Series DF).
We will continue to support the older style LH and LA Series Direction Finders with repair service and some accessories.
We are providing information and specifications, as well as Operating and Maintenance Manuals where applicable, on our discontinued equipment for your convenience.
