Hello friends, I have been looking at the lack of 60m wspr activity in N. America and finally came up with a plan to remedy that problem. In retrospect it should have been obvious long ago. Firstly, the common worldwide wspr frequencies are 5.288700 and 5.366200. Unfortunately, neither frequency fits into the NA ( US and Canada) legal bandplan. So, there has been no (legal) N. American wspr operation. For those who don't know, wspr transmissions are conducted only on USB and are basically a 1500 hz tone that varies by a very small amount. So they are very narrow bandwidth. There is a channel on 60m (operations on 60m are channelized), 5357.0, that is currently used in many parts of the world for JT-65 operation, which is a cousin to wspr. Jt-65 is similar to wspr in that it also uses a 1500 tone as nominal center frequency, but it also allows the user to change that transmit anywhere within the USB bandwidth, defined as 2.8 Khz. However, most JT-65 users never go below 300 hz for transmit. So, here we have 300 hz, from 5357.0 to 5357.3 that is never used, but is a legal frequency for N. American users. What to do? Very simple. If you tune your wspr transmitter to 5355.7 USB, you will generate a 1500 hz tone at 5357.2, which is within the legal 60m NA channel. And because the wspr receiver bandwidth is 200hz wide, that means that being centered on 5357.2 means that you will have a buffer of 100 hz at the bottom of the channel to catch those poor unfortunates that sometimes go astray. This goes back to what I said at the beginning. It is a solution so obvious that I'm surprised that no one has thought of it before. To sum up: Additional use of a legal frequency that is already in use by digital users. No interference to the existing users. And finally, no need to negotiate new allotments from any organizations. What's not to like? That's my proposal. And for those interested, I am currently operating during appropriate hours on 5355.7 USB wspr. Legally.
