|Thanks Martin, that says it all.

I've listened on portables for years, but just passed my tech exam and upgraded my equipment. A HOA restricts what type of antenna I can use, so I'm running a Cobra Ultralite Senior dipole as an inverted V, hoping the HOA won't spot it. The Cobra comes with fantastic weatherproof ladder line, which I'm thankful for given the two environments I call home (rainy Oregon and scorching Arizona). Now here's the question: I know a dipole will need a balun, but I've seen conflicting advice on where it should be placed. Here are my three options as I see them:
1) Place the balun at the apex of the inverted V I could put it in series with the ladder line, then run the ladder line indoors to a PL259 and my low-pass filter.
2) Place the balun indoors at the end of the ladder line, so it is between the ladder line and a length of coax to the low-pass.
3) Place the balun at the apex of the inverted V and run coax all the way up to it, eliminating the ladder line altogether.
Clearly Option 3 is not the way I want to go. Among other advantages, I can run ladder line under a window without drilling any holes in the wall. But placement of the balun, at top or bottom of the ladder line, is the question of the day. I appreciate any suggestions!
Thanks and 73s.

|Thanks Matthew. I do have an old copy of XP, but I'll only load that on a partition as a last resort. Offline discussions with a few knowledgeable gents has confirmed that the radios themselves do NOT run Windows. Manufacturers want users to have Windows so that they will be able to open Windows-enabled zip files of future firmware updates. Otherwise, Windows is unnecessary. But having said that, Yaesu told me directly that they have never tested connecting their radios to any OS other than Windows, so cannot safely recommend any other OS. I'd say it's about time they got off their butts and tried some new operating systems - like the rest of us.

|I run Linux Mint. I'm considering buying a Yaesu FTDX1200 or Icom IC-7410. The manuals for both indicate that they require connection to a Windows pc in order to install USB drivers.
Could these USB drivers by installed by running an emulator in Mint, then connecting the radio?
Does anyone know if either radio contains other Windows-specific software? In other words, would either radio be dead in the water without an emulator running?
My plan is to connect the radio to the Mint pc, then run Linux programs (logging, etc). I've noticed the Ubuntu Hams group and others, but no idea if any compromises must be made in order to get the radio and Linux to play with each other.
Thanks and 73,

|Just a quick message of thanks to the license exam question writers appointed by the NCVEC. I'm studying for my first license and going through the usual nerves - this will be the first test I've taken in years. So I was very thankful for the wry humor offered in Question 281 / T7C08, which provided a wonderful break. If that question comes up on my official exam I'll be sorely tempted to incorrectly choose "iambic pentameter" as the answer. Many thanks to the unidentified poet among the NCVEC question writers.|
