OK, discovered why there is audio only on the 2.5 and 5 MHz bands: These bands disable transmit...so the transmit-when-on problem is still there.
It looks like there is a comparator on the MC3302P IC that is outputting high even though its two inputs are relatively equal (U301D, inputs of 9.6V and 6.0V should generate a low output...instead, it's high and appears to be keying the transmitter via U302). Anyone ever seen this IC go bad? --Brian/WA3ITE _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
