It turns on by itself at anytime. It will stay on until someone turns it off, then will randomly Thu, 08 Oct 2009 19:14:30 GMT Bigjed http://groups.yahoo.com/group/FRG-7700/message/837 http://groups.yahoo.com/group/FRG-7700/message/837 ...

However, I am a bit disappointed with the mediumwave sensitivity. The figures stated in the Wed, 30 Sep 2009 17:42:34 GMT Thomas Carney http://groups.yahoo.com/group/FRG-7700/message/833 http://groups.yahoo.com/group/FRG-7700/message/833 On that point, I stand corrected.  You're right, the front end of the '7700 is too broad and I had forgotten about the octave filters.    A pre-selector Wed, 30 Sep 2009 10:06:29 GMT g4gvw http://groups.yahoo.com/group/FRG-7700/message/832 http://groups.yahoo.com/group/FRG-7700/message/832 Hi All, Slightly at variance with that one Tom. While you are right about the impedance matching situation, it is worth bearing in mind that the FRG like many Tue, 29 Sep 2009 17:09:25 GMT rscha19306@... http://groups.yahoo.com/group/FRG-7700/message/831 http://groups.yahoo.com/group/FRG-7700/message/831 I have a couple of other radios for comparison, using a short (20 foot) wire antenna. Yes I do have the manual and the power supply is good. No RF test Tue, 29 Sep 2009 15:19:06 GMT Thomas Carney http://groups.yahoo.com/group/FRG-7700/message/830 http://groups.yahoo.com/group/FRG-7700/message/830 Don't waste your money... the receiver has such high dynamic range that you can receive a lot of signals without having to match the impedance, especially if Tue, 29 Sep 2009 10:35:53 GMT g4gvw http://groups.yahoo.com/group/FRG-7700/message/829 http://groups.yahoo.com/group/FRG-7700/message/829 Hi Dick Can you supply some more info. eg: Do you have the handbook? Do you have something with which you can compare it? What are you using for antenna(s)?

I am in the U.K. Tue, 29 Sep 2009 01:32:18 GMT Howard Stanyon http://groups.yahoo.com/group/FRG-7700/message/827 http://groups.yahoo.com/group/FRG-7700/message/827 Thanks for that. I will check the batteries and contacts first and then, if the fault persists, I will try to determine the offset and get back to you. ...

I cleaned the local/distant switch Mon, 28 Sep 2009 23:59:25 GMT g4gvw http://groups.yahoo.com/group/FRG-7700/message/825 http://groups.yahoo.com/group/FRG-7700/message/825 Hi, A few thoughts on this one from experience: 1st As suggested check battery and battery contacts and connectors. If this doesn't resolve then remove power, Mon, 28 Sep 2009 17:51:20 GMT Thomas Carney http://groups.yahoo.com/group/FRG-7700/message/824 http://groups.yahoo.com/group/FRG-7700/message/824 Agreed on the batteries and contacts.   Secondly, note on which frequencies the memory is off by.  You may find a pattern.   Now, frequencies stored in
