Working some JT-65 this afternoon

A decent showing on 20m JT-65
I had the day off today as I was called in last evening and worked through the night so I thought some radio time was in order! I wanted to try some digital using WSJT-X's program and JT-65 seemed as good as any mode. At first I attempted to just run JT-65 on it's own as I have done many times in the past. This time for some reason most times when the rig went into transmit my Elecraft K3 stopped transmitting and gave me an error message of ERR PTT. I did post this issue on the Elecraft reflector and got some great feedback BUT I wanted to get some JT-65 in! Next was to try the "back door"
My spots on Hamspots
approach by using Win4k3 suite rig control software as I also have WSJT-X set up under 3rd party AUX/CAT port. Using WSJT-X this way worked like a charm as most of the feedback on the Elecraft reflector site pointed toward software issues and not rig troubles. There was a nice amount of DX on the waterfall that I was decoding but when I checked on Hamspots to see who and where was receiving my 5 watt JT-65 signal it was all U.S so that was the spots I attempted to contact. I also threw my CQ out there as well to see if any local or DX heard me. KG5ICI came back to me from Texas Chris gave me a signal report of -16. I was not on the radio too long but it sure was nice and relaxing.

    I too just worked some great dx this morning. On 160 meters I worked Hawaii and Australia using JT65. Those who don’t use JT65 are really missing out.

    I run Win4K3Suite+com-0-com+Log4OM+WSJT-X+JT-Alert and they play nice together. I have two K3’s. One runs only QRP 1- 10 watts PSK31/63, Olivia and WSJT-X. (OK sometimes I cheat and go to 25 watts for PSK) I use the 32 bit version of Win4k3Wuite for that one.. At the same time I run the 64 bit version on the same computer to control my second K3+KPA500+KAT500. It is a Gateway quad core laptop.

    JT-65 is amazing 5-10 watts are netting me contacts that 500 watts with the same antenna has trouble doing. It is ping-pong radio i.e. tx-rx-tx-rx-tx-rx-73, but it really can be fun and yes relaxing…IF you have not tried it yet, you should… 2 cents.. back under my rock…73

    Good morning Tony, it sure is a nice mode and even when you hear of a solar storm in progress it seems that these digi modes still net contacts.

  • Mike VE3WDM:

    Good morning Harry always nice to hear from you, I run Win4K3, Log40M along with WSJT-X as well (less the JT alert) I have one QRP K3 and KX3 at 1-15 watts. When on the air I keep the output to 5 watts as I am in a condo and do not want to make “contacts” with those who live beside me! With most of my other rigs in the past (FT 1000MP, FT 857) I kept the digit output at 50% of rigs full output as recommended by manufacturer…….I haven’t really looked into Elecraft take on this with their rigs?
