I'm using a 205 purchased new in 1996 in front of an Etude. It has not had the problems you describe. Sounds like you have a serious calibration issue that should be handled via warranty. My unit has been helpful in my reception situation -- I'm about halfway between two large East Coast cities, and their signals are fairly weak due to distance. I have a few very strong local station signals that tend to overwhelm the dial. The 205 boosts the weak signals significantly, while not emphasizing the strong locals.
Magnum Dynalab 205 FM Signal Sleuth focusing bad?
i recently bought a used Magnum Dynalab Signal Sleuth (model 205). and it has a BIG problem... the focusing control is not working in the right range. for instance, if i were to be listening to the channel 91.5MHz on my Yamaha TX-950 tuner, i would have to set the 205 to about 95-96MHz. so, in other words, it's off by about 4-5MHz. and that is a terrible problem if you want to listen to say, KROQ, which is at 106.7MHz... cause the knob doesn't go above 108MHz, so i can't even use the 205 with that station!
also, another problem is that the gain control is labeled wrong too. it has the 0db position at about 10:00. however, the actualy 0db position is at 12:00. now, this might suggest that the unit is capable of more boost, but somehow the knob or the circuitry it's associated with isn't going high enough.
i dunno....
the guy i bought this from said he sold 2 other units previous to mine, and both had the same problems. so, it seems they're all like this......
you guys have experience with this signal amp?
