Dear Elecrafters,
Local telecommunication authority is considering 60m operation for the hams in VR2. For output power of 15W PEP, using a dipole for NVIS, what would be the likely usual communication range 7/24 round the clock? 100km radius? Any advice will be appreciated and thanks for the band width here. 73 Johnny VR2XMC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

In the mid to later 60's while "vacationing" in SE Asia, most of our
in-country net frequencies were in the 5 MHz range. Generally, it was 100W [KWM2A] to a low dipole [GRA-4]. From Vietnam, we had no problem with stations in the Philippines, Thailand or anywhere in-country. That's about 8 dB more than your 15W, a tad over 1 S-unit. Having CW and Data [<2.8 KHz BW] as well as USB is probably more important than power. 5 MHz sometimes went long after sunset but still worked. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 3/2/2016 12:52 AM, Johnny Siu wrote: > Dear Elecrafters, Local telecommunication authority is considering > 60m operation for the hams in VR2.

I haven't used the band but I would expect it would have characteristics similar to the 80m and 40m band. Those bands are generally short range during local daylight hours and can be around the world after sunset. -- Cheers!

I use 60m occasionally and I don't think it is "reliable" 24/7.
especially for only a 100km radius. 60 tends to go long in the evenings. It works well as one tool in a toolbox with several tools. But I think it shines for longer distances than 100km. As others have said, it's better than 80 during the daytime and better than 40 in the evenings for short distance. But don't be surprised if 400 miles (600 km) is the closest you can work some evenings. I would also suggest higher power to help with poor propagation and/or summer QRN.
