Congratulations! Easy, isn't it?
Im glad you're already considering more, it's far to simple to just pick up a cheap handheld, use it for the local repeater and then get bored.
Been reading / watching lots of reviews on base stations, itching to get my first base TRX setup, lots of choice though
A lot of people will tell you to get an Icom-7300 and it's good advice, it's a very nice wireless but I don't find it ergonomically very straightforward. I'm sure it's perfectly fine after sitting and using it for a while but we had one on GB55RC last year and even over the course of a weekend, I just didn't get on with it.
When I was looking for an HF radio after my 847 was destroyed, I went to W&S and sat there for the best part of a day just playing with different radios to see what I liked the feel of. The one I found the most intuitive to use and where pretty much all the regular controls you're going to use are on the front panel, rather than having to dive into menus was the TS-590 and it helps that it's got a fantastic receiver, right up there in terms of performance. I bought one along with the associated voice module and although it's a superb radio. I upgraded from the original model to the SG a while ago, just because I'd managed to scratch the screen and it annoyed me! There are many 'shack in a box' radios but they're all compromises. Radios like the 859/897 are dreadful to use with so few controls and everything being menu driven and the receiver is awful. They're sensitive enough but they have no selectivity worth talking about. Don't even start me on the 817 or the 703
If you want a good, solid HF radio with a very good receiver, for sensitivity, selectivity and ease of use, you can't go wrong with a 590 and the original 590S can be found second hand for an absolute steal.
