Model 60 Woes continued
#2

Hello Ron. ..., generally speaking, I have found the early TRF type circuits leave alot to be desired on all-across the entire AM band reception!! However, the audio quality produced from these old type receivers is Awesome!! Back when TRFs were made, several AM Stations were transmitting at very high wattage levels (all day & night). Some as high as 500kw. Signals from those old Radio Station transmitters could "wake up" a simple-designed AM receiver in those days!! I have many restored TRF radios in my collection, and as much as I enjoy listening to them from time-to-time, the "antenna-feed" longwire antenna designed circuitry was a low-cost way to "link" to the most powerful stations on the airwaves. Down here in Texas, I can receive a VERY few powerful Mexican stations on the low end of my TRF dials, as some of them Mx AM broadcasters are still using over 100kw transmitters. Otherwise, its "hit or miss" using these old TRF receivers. I have also found that even a short 25' outdoor longwire antenna can "overload" some TRFs circuits receiving capabilities!! I have found using a 250 pf mica cap in series with the antenna lead wire really helps sometimes. You might try that, but most old TRF designed radios are "touchy" as a old maid at a "stagg convention"!! Sounds like your TRF radio is working just as well as most from that era to me!?
