Hello OldTech! I just read you have a Yamaha T-80. I've had one for years, and it is a very good tuner. I'm not sure you are interested in this, but this tuner is also well known in the AM DX community as being nothing short of amazing on AM. If you can ever hook it up to a decent loop antenna, you'll be surprised at the results. The best type you can get now that isn't very expensive is a 12" tunable loop which Terk makes. It does ok on a traditional AM loop as well.
I'm about 90 minutes east of you, near Buffalo, and with a 12" tunable loop, especially during the winter months, I can tune in Chicago stations during the evenings regularly (720, 670, 780, 1000), and I can get live broadcasts on Saturday night from the Grand Old Opry out of Nashville's 650. If I 'point' the loop during the south, and if the conditions are decent, I can tune in stations from Cuba on 600 and 620, Baranquilla, Colombia on 760, and Caracas, Venezuela on 750 and 780.
If you are going for these long distance stations on AM, make sure you have the Filter (FM NR/AM Amplification) switch turned on... it helps reduce adjacent channel interference. Also, you can take advantage of the Fine Tuning Control to tune a bit further away from a noisy local station.
Finally, one other useful tip for the T-80, and this is regards to FM. I and others have found that if you going to use an indoor antenna on FM, the best hook up is a single wire, 3 to 5 feet long, hooked up to only one of the 300 impedance hook ups on the back of the tuner. Don't ask me why this works, but it really does!
I hope you continue to enjoy your T-80, and if you do try any of the above suggestions, let me know your results.
