I can help you too. We were playing quite a bit on 145.580 during May and June. That might be a good place to play on simplex; possibly catching someone else monitoring. Post a note with a couple hours notice (if possible) for when and where you will be on. It looks like you are probably hooked into the 6 pin data jack on the Kenwood, so you can easily talk on the same freq to iron out any problems. A couple of hints that catch a lot of beginners-
1) Be sure the Signalink is plugged into the computer before you turn it on.
2) Double check the soundcard settings in FLdigi for "USB Sound Device". If not remembered by the software, save config, exit, restart and check again. (see step 1)
3) Watch your FLDIGI squelch control (slider at bottom right). You need to adjust it down close to the noise level. Requires fiddling when you change modes.
