Author Topic: Ten Meters and Channelized Operation  (Read 964 times)

I've recently gotten back on 10 Meters. I'm running a little Radio Shack HTX-10 Tranceiver into a Mag Mounted 3' Firestick. I'm located in Sebring, Florida and am particularlly looking for any stations that may be on in or around this area.

I wrote an article for 73 Magazine in the October 1978 edition, "CB to 10", about modifying a PLL CB rig to 10 Meters. At the time I had set it up for channelized operation, with channel 1 being on 28.760 and channel 23 being on 29.050. Since the majority of activity now is on SSB, are there any corresponding channels being used on 10 meters? In other words, if you were using a converted SSB CB rig, what frequency would you put it on for channel 1? My rig can change frequency in 1, 10 or 100 khz steps. Since it is easier to scan a large area in 10 khz steps, I selected that. I usually scan from 28.305MHz and then 28.310 up.

Can someone tell me if there is any commonly selected frequencies that are monitored during mobile operation? Someone told me that 28.345MHz or 28.380MHz were used for that but I'm not sure. Years ago I monitored 28.800MHz listening for 10-10 International nets. I understand they still have them there too. If anyone has any comments or suggestions about this, I'd be interested in hearing it.

To my knowledge there are no "channels" on 10 meters, with the possible exception of the illegal truckers who propagate 28.085 with their Pilot Ranger radios.

I did read the article, and there have been others as well. Aside from the legality issues, most of the converted CB sets I've played with all have excessive IMD. Personally, I prefer my 706.

He's not asking for channels, he's asking where on 10 people are working, so he can re-frequency his converted CB rig there.  CBs are by necessity channelized.  But, with an Incremental Tuning control, they can tune up an SSB signal that's not on the "channel".

During the last contest, I worked a few 10 meter contacts from about 28.5 to 58.575.  But, I didn't have a 28.3 crystal in my KWM-2A at that time, so I can't say about 28.3-28.5

Thanks Bob, you hit the nail on the head. As you figured, I'm not using a "channelized rig" but was inquiring if 40 channel SSB rigs were converted, what would the converted frequencies be.

I doubt that even pertains anymore. With all these HTX-10 Tranceivers available, who needs to convert a CB rig! I guess I probably could have simply asked what frequencies are usually monitored when operating mobile on 10, hi hi.

Thanks again Bob.

I also bought an HTX-10 ($89). At first I was afraid that it would be a cheap low performing modified CB. I was supprised by its performance. Using a simple dipole at 15' the first station worked was Ireland! I have since gotten an IC-718 but the HTX-10 still sits on the bench.
