I remember listening to somebody comment back then, that there was a group of hams that was doing FM on 160. BTW, if I remember right, you can only do FM (as NBFM), below 29.0 Mc, if the bandwidth isn't greater than the bandwidth of an AM signal, and the modulation index isn't greater than 1. If I remember right, if your ricebox was like my FT-897D I sold in July, the FM bandwidth was probably, the standard bandwidth for 10m FM & above - 15 kc. Did you change the deviation of your rig to comply? Only a very few rigs were made in the late 40s & early 50s to the NBFM, 6 kc standard - Collins made an NBFM adapter for their rigs in the early 50s; the Hallicrafters HT-19 comes stock with NBFM capability, and I think the Sonar Company made an NBFM exciter. CQ Magazine's, Radio Classics column talked about 6 kc NBFM in the July or August issue. 73, Ellen - AF9J ______________________________________________________________ Our Main Website: http://www.amfone.net AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
