JT65A

For discussion of MGM (digimodes) on 4 m, e.g. PSK, FSK

JT65A

Hi all,



Just wondering if JT65A is used on 4m, as it's quite widely used on 6m, I have never heard it on 4, only MSK on 70.280. Indeed is there a allocation for JT65 A ?

Cheers

Indeed difficult to find clear information about JT65 on 70 MHz:

WSJT-X V1.7.0 indicates 70.091 as center frequency for 4 m, but in the RSGB bandplan 70.0 - 70.1 is the area for beacons.

It would be clearer to use 4 m analog to 6 m:

50.276 JT65
70.276 JT65

50.280 MSK144
70.280 MSK144

Would that be a simple thougt?

Hi Jeremy,

tnx for info. I will try to monitor 70.176 for JT65A (skeds via KST).

Just made my first FT8 qso on 50.313. Is there already a frequency for 4 m? WSJT-X V1.8.0 is suggesting 70.100

Hi Harry,

I think 70.100 would be very unpopular as it is in amongst the beacons, I have never heard this mode on 4m yet.

I noticed a few spots lately on 70.174 also for JT65, so all activity seems to be between 70.170(DL) -70.176

Best 73
