Message-ID: <13395@sri-arpa.UUCP> Date: Tue, 11-Sep-84 12:25:00 EDT Article-I.D.: sri-arpa.13395 Posted: Tue Sep 11 12:25:00 1984 Date-Received: Tue, 25-Sep-84 00:36:25 EDT Lines: 14 In my experience, antenna tuners are generally a waste of time for receiving. If the receiver is any good, the limiting factor is usually noise and interference external to the receiver. The tuner affects the desired signal and the undesired interfence equally, and does nothing to help you discriminate between them. If your receiver is so poor that you are limited by received signal strength and receiver front-end noise, you'd do better to get a preamp. For most receivers, this will be of significant value only on frequencies above about 15 MHz, but if you do a lot of listening up there, it might be worth it. 73, John Sangster, W3IKG jhs at mitre-bedford
