ft8 160m

Post by tvdxrools » 06 Jan 2018 06:40

a bit off topic but good way to test your antenna , at the time of the recording transatlantic dx had dropped off a wee bit but as you will see with the grab at the end Texas Florida etc was received also note i have no back null at all on 160m with the beverage as its set for mw but it let Kazakhstan come in and i have also noticed that if props not bad on 160m to the USA it doesn't mean mw is good as when i was getting Texas etc on 160 mw was still very poor , David

You must still have a back null on 160m - https://en.wikipedia.org/wiki/Beverage_antenna

Wow! I've never heard of JT8, but I see it's a new mode. I keep meaning to set up my SB-2000 for WSPR, but I can never get it configured. I'm sure YouTube will have the answer. If not, maybe they can help me at the Eagle Radio Group next week.

I wonder how JT8 compares to WSPR in terms of the accuracy of weak signal detection?

WSPR would be superior. FT8 has been designed as a quick QSO weak(-ish) signal mode. Unless other digital modes such as psk, jt65, jt9 you can use high power on FT8. You can complete a QSO within 60s or less with FT8 as opposed to 5/6 mins with JTxx.

Thanks for the info. Will consider these and decide. I think it's probably going to be WSPR.

The other major difference with wspr is that it is not a 2-way QSO mode - it's akin to a personal beacon.

That's what appeals to me Stuart. As you know. I am not one for wasting endless minutes (and hours!) trying to break through pile-ups. That was never any fun for me. I do 'get it' though. It's rewarding to have to do a bit of work and then, hopefully experience the sense of achievement when you finally DO get on top and make the contact, but what a waste of time in the process. It usually doesn't work for me. WSPR completely automates things and I can still receive and transmit, without the hassle and I can get on with other things.

JT8 also appeals, so maybe a bit of that too.

Again, really interesting David. 'Boredom' is the word. What a pathetic season for such a low point in the solar cycle. It's all gone wrong. I am wondering if it will actually be better next season. Alternative hobby needed.
