开云体育For you FT mode folk,For Field Day, Try to use FT-4 as much as possible. Use FT-4 until you run out of people to contact. Then switch to FT-8. Do FT-8 for like 30 minutes and then try FT-4 again. Reason? Really simple! You can make twice as many contacts for any given amount of time! BUT, BUT, BUT, FT-4 is not as sensitive as FT-8. While this is true, And FT-4 is about 4 db less sensitive than FT-8, and that is HUGE in the VHF/UHF world! Where you have quiet bands, and no interfering stations. 4 db is gigantic! Especially when you have a chance to get anywhere near the max sensitivity of those programs. But On the HF bands with a LOT of band noises, in addition Field Day with the kazillion of competing signals, you are not gonna get anywhere near the program sensitivity spec's anyway. And 4 db? it is not even 1 S unit. it is only 2/3rds of a S unit difference. During Field Day you are NOT gonna see this difference. If ya wanna get some awesome FT contest type of operating practice, every Thursday evening is a 30 minute sprint, that it's sole purpose is to make you a better FT contester! Details can be found here. Give it a try, it's kind of fun! Joe WB9SBD |
