Pete, As I've previously reported, I live in a high RF environment with 5 stations within 5 miles, 1 of them under 4 miles and the other 3 under 3 miles. I have two 37's. One is modified, the other is not. One has a scavenged 6 kHz filter from a Sangean ATS909. It has done a remarkable job of controlling the locals and the sound is very good. One would not believe it is the same radio. My experience with filtering a.m. on my Drakes is that 6 kHz is more pleasant to listen to than 4 kHz filtering. Normally I would suggest trying each in the 37 to determine your preference. However, the board is fragile and can't stand a lot of soldering/desoldering. YMMV. I think it would be possible to solder in SIP/or "shady tree engineered" IC sockets that would facillitate filter change out. The filters must be laid on their sides to fit between the boards. Have Mr. Wizard think of this approach. I think it will work. I'll probably do this approach on the second 37. If he would like, I can email him photos of the work with directions. 73 Gil _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca
