Title: 6 Meter digital freqs
Post by: WB6RLC on May 28, 2012, 07:13:47 PM
Now that 6M is starting to open up, I'd like to do some digital on 6.
What is the SSB PSK freq?
What is the JT65 freq (non-EME)?
Do they use JT65-HF?

Thanks
Glenn

I don't think there are any hard and fast rules for digital modes on 6M - not much activity. 50.290 has been recommended by some as a PSK31 frequency. I've done some calling there during band openings but no response. Probably everybody too busy making SSB contacts on the lower end.

As long as you stay above 50.125 you are probably okay.

For meteor scatter using WSJT FSK441 and ISCAT 50.260 USB is the calling frequency.

For Eskip using ISCAT or JT6M 50.230 USB has been a spot where Folks looking for DX have congregated.

ISCAT...
I've read some data to support that ISCAT is the best mode to use on 6M...better than J65...I've downloaded the WJST9 program but cannot for trying every option--get the program to work...either in transmit or receive!  I use WSPR and J65 so am familar with the modes...but this WJST9 has be beat..ANY help would be appreciated.....
FYI I do hear 'lots' of action on 50.260mHZ so assume its ISCAT.

The few PSK QSOs I've had on 6m have been at 50.290.

DIGITAL BAND(guide..not official) PLAN FOR VHF/UHF

This is NOT an official band plan but a guide for most "normal" digital activity and areas will vary in different places so please use common courtesy and if you are unsure ask local operators and or listen.....but never run digital on the SSB/CW calling frequencies or the EME subbands

" ... not much activity" ???

Possibly you should try JT65 on 6M at 50.276. Yesterday afternoon (6/3/12) there was about 3 hours of non-stop wall to wall (on the waterfall display) JT65 activity from SoCAL all the way to the New England area. I worked several upper East Coast and NE stations and others stations as far south as VA and NC all the way back to CO and UT, all on JT65 on 50.276 Mhz (6M).

Thanks Gene.

That was the freq I was looking for.  I'll give a listen.

I'll throw in my thanks as well.

I'm discovering that leaving JT65HF open, with the transceiver tuned to 6m is a nice way to get in a little radio time while telecommuting.

Without a real 6m antenna, I don't hear much, but I'm happy when a little green bar shows up in my peripheral vision, especially if it's from a grid I don't have confirmed yet.  :)

On a related topic, does anyone know for sure if JT65 QSOs are valid for the upcoming VHF contest this weekend. I looked on the ARRL website and there was no mention of any particular modes, only the bands to use and need for exchanging grid squares which I already knew about.

I figure if 6M isn't open too well that maybe I could pickup a few points on JT65 while awaiting the big SSB opening. I have actually had JT65 Q's on 6M when the SSB/CW portion was dead as the proverbial doorknob. Guess that is something to be said for DSP processing.

Sure. JT65 QSOs are valid in the ARRL VHF contest if the exchange is complete.

I have made many valid JT65b EME QSOs with K5QE via EME in this contest for example.

 ;)  Many thanks for this thread!
I tried working PSK31 on six meters but didn't know the recommended area.
Now I do.
Hopefully can make some contacts!
20 meters was really busy last night ... terribly so ... as I've never made a voice conact on six, hopefully I can make a PSK contact on six!   ;D  (More than just one would be okay too ... insert innocent expression here ...)
