I am looking for a great cheap but powerful vintage am radio. The ones that I have just cant pull the signal in that I want. I love listening to talk radio but I live way out in the country and can usually only pick up my favorite station in the summer time and even then it's not that good. It just seems that the newer radios are just not as strong as some of the old ones. I have a little Kaito multi band radio and two other newer type radios. I am 60 miles from my nearest station. Do I need to invest in a great vintage transistor radio or do I just need one of those round indoor am antennas? Thanks
A loop antenna would help in any case. If you are interested in a genuine vintage radio, you should be aware that almost any of them from the mid-70's or earlier will require some refurbishing to work their best. It's not very hard in most cases, but probably necessary.
Assuming you want a transistor radio, I would suggest a GE P-780 or a Zenith Royal 2000. Both were intended to be the highest-performance radios possible, and the Royal 2000 was the very first AM/FM portable radio, and arguably the best ever made. They tend to be rather expensive ($75 at eBay prices). An alternative is a "lunchbox radio" like the Zenith Royal 755, which has very good performance, very good sound for AM, and is dirt cheap.
An alternative is a multiband portable radio like the Zenith Royal 1000/3000 or 7000. I won an informal "DX Contest" here a few years ago with a Royal 1000 and a loop antenna, picking up a 5000 watt station in Hawaii from here in Sunnyvale, CA, about 2400 miles. That's unusual (and there's nothing but salt water and a line of hills between here and there), but tells you what can be possible during nighttime on medium-wave.
