So I went and bought one of these cute little Tecsun radios that have the signal strength dbu meters in them. Why? I guess because I felt like it at the time :) I've always wanted to take one of these out and compare the dbu numbers to actual field strength readings in volts (well, mv anyway). Theoretically, if these radios are built with any decent quality control I should be able to determine what dbu = what mv, etc. and if this holds even slightly accurate from radio to radio ya'll could use the info for some non-scientific field strength readings. Seems to me there was an outfit selling Tecsun radios that came with a chart that did this, actually (at a rather steep markup if I recall). So, anyway, something to play around with.
At first I thought I had received a radio for a different country. Only tuned to 1620 (which worked for me since my station is at 1620) and the ad sad AM tuning 520-1710. but I discovered when I changed the AM tuning step from 9 to 10 KHz, it also changed the band for AM from 522-1620 to 520-1710, also changed FM from 64-108MHz to 87.5 - 108 and changed the temperature from C to F. Thsi wasn't mentioned in the instruction booklet (although I admit I had to read it with my reading glasses AND a magnifying glass).
Anyway, experiment results to come :)
