#Jt65 radio full#
This is one of the more tricky modes to set up for, and this won’t be a full “how to” guide, as there are plenty of those online already. A screenshot of the PSKReporter website, showing received signals Setting up for JT65 You can also use the great online PSK Reporter website to see where your JT65 CQ calls are reaching, making it great for checking your antenna’s performance. You also don’t need a lot of power to make a contact – you can work the world on 10 watts. It also works many dB below the noise floor, so although you may not be able to hear any signals – they could be there. JT65 handles very weak signals, just like WSPR, so will get through where voice and PSK31 won’t. It’s a case of tuning in to a JT65 frequency, waiting for one-minute transmit cycle to complete, and looking for a CQ message to reply to. You’ll see from the above screenshot that there is a “waterfall” (as with PSK31) that shows multiple QSOs. One person sends on the odd minute, and the second person sends on the even minute. M0PSX says Reception Report Received (all OK)Įach message of up to 13 characters is sent over the course of 50 seconds, starting at the top of each minute, so the above conversation would take seven minutes. Here is a typical conversation over JT65: “CQ M6PSK JO01” With JT65, you’re restricted to very small messages, with a limit of 13 characters per message.
It’s also great for making contact over distance with low power, where a voice signal just can’t make the trip.Īs with modes such as PSK31 and WSPR, you interface your HF rig to a computer, and send out text encoded by your computer over the amateur bands. JT65 is one of the more specialist data modes that I’ve played with, but I must admit, it’s quite addictive.
