<> The converter is only about 4x4x1". It can tune *parts* of the 19, 25, 31 and 49 meter bands. There is a button on the front for each band, and they are ganged to the on/off-bypas switch. There is an LED on/off indicator. There's good news and bad news, mostly good. It does a very good job converting for my car radio (an AM/FM Ford OEM). It down converts on a 1:1 ratio to the tuning strip. Shortwave comes in between approx 800 and 1200 Khz, giving a 400Khz slice of each band: 19m 15075:15475- 25m 11638:12038- 31m 9438:9838 and 49m 5875:6275. Reception is about on par with a $100 portable, BUT with a much better bandspread. Heavyweights (RCI, BBC, DW, etc.) come in with hardly noticable interference. If a station is down in the dirt, it's lost. Nighttime reception is great, daytime poor. Suprisingly, there is hardly any fade. Now for the BAD news...1) It cuts heavily down on regular AM reception (I know, I know, I should thank heaven...). FM sensitivity is left unchanged. 2) My car electrical system causes so much RFI, that I might have to license it. I can quiet the ignition system, but weaker stns get wiped by, say, the windshield wiper motors. 3) The 'mounting hdwr' supplied was a joke. A trip to Radio Shack was necessary. All in all the MFJ allows me to fulfill a childhood wish of DXing in the car, and gives me something to twiddle with in traffic. It's worth the $80. M. Kenig, ATT-IS S. Plainfield

#R:abnjh:-67300:trsvax:52800020:000:362 trsvax!mikey Jun 12 09:28:00 1984 If it cut down the AM sensitivity, retune the car radio. There should be some external adjustment labeled "ant tune". It may be internal to the radio and more trouble than it's worth, especially if you don't care about AM that much. However, you may want to retune it for maximum reception of the shortwave to increase sensitivity. mikey at trsvax KA5MJQ
