Re: [Drakelist] SW Crystals Suggestions for the R-4B?
Aaron, I notice that no one has really answered your question. For my listening enjoyment, I like the ranges 5.5 to 6.0, 6.0 to 6.5, 9.0 to 9.5, 9.5 to 10, 11.5 to 12, 15.0 to 15.5 and 17.5 to 18. If that's to many crystals, the grouping around 9 to 12 megs in the evening brings the most international broadcast in. The 6 meg ones are becoming largely "shortwave evangelists", both living and dead, hi. Hope that helps!! Old time shortwave listeners on Drake gear have found a crystal frequency that gives like 5.7 or 5.8 to 500 kc up from that and solved having to have two crystals in the 6 meg range. If I run across mine in a drawer, I'll let you know what they did. 73, Don, WB5HAK___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist

At 20.8 in the transmitter and a 21.1 in the receiver will work fine as long as I don't use it in Transceive mode. Still doesn't solve the SW dilemma.

There is a slight variance in the proper crystal used between the R4 and T4 but it works fine. I use my twins on 30M all the time. There is some fine print in the crystal selection chart that allows for this.

The plan is to run 160, 30, 17 and 12 on the transmitter. Correct me if I'm wrong but I was under the impression that the older Drakes should not be used on 30m (or anywhere else within the 10.5 to 12MHz range) due to the possibility of spurious signals arising from beats with the VFO. —Carl Maniscalco, KJ6BSO ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist ___ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
