On the left is a Grundig RF 121u not working I got for free. The middle on is a nice little AM Tube radio made by Farnsworth in 1946. It is a model ET-066 and it does work. My Dad picked it up for $20.00. The radio on the right is a working Grundig TR-807 a co-worker gave to me. Pretty happy. I think I can fix the little Grundig stereo. I suspect it is a bad transformer.

I own a Grundig TR 807 radio. There has been much criticism as to this radio's poor overall performance on shortwave. The radio's included antenna for shorwave reception introduces much noise, in that the low signal-to-noise ratio results in overall poor shortwave performance. However, there are 3 fixes that greatly improve reception: Attach a good ground wire from the radio's ground terminal to such a ground as a grounded table lamp. Also, detract the antenna and attach to it a reel in antenna placed near a window. Last, make that sure you clean the various band selector buttons with RS Tuner Cleaner lub. (with age they tend to reduce sensitivity). These 3 fixes now make the radio's background noise much less, and now I can get excellent performance equivilant to my NP RF-5000A. What's great about this radio, once you get rid of all the noise, is that the tone of the transmissions are very good to copy. For example, All India Radio now comes in very clear with pleasant listening volume/tone. So, just give this radio some TLC and it will amaze you in how good a radio it can be.
