    735's are pretty bulletproof, I have to recommend them unless you're a serious phone op - there's no selection for different ssb widths. PBT is good though and makes up for it.

    Good radio that unfortunately has a couple of dumb design decisions, that STUPID FLIMSY DOOR being #1.

    Still, I'll never sell mine.
    Pretty easy to fix, too, with the service manual.

    W4INF-- thanks for posting the video! That was great! It was nice to see the rig in action.

    I took the plunge today and ordered the IC-718. They will ship it Monday and I should have it the next day.

    In the meantime, it's up into the attic (I live in a condo and no outside antennas are permitted) for me tomorrow and get the antenna installed. It should be fun as I have to walk on the rafters as there is no floor installed up there! If I work on antennas very often, guess what's getting flooring installed?

    Again, thanks much for the info and advice, I appreciate it.

    73,

    Ok, yet another dumb question.

    It appears that the 718 allows only one additional filter. If you add the 500 hz CW filter, does it affect the SSB reception or is there already an SSB filter on this rig?

    I have heard of a W4RT filter that evidently replaces the SSB built-in filter and adds a 500 hz CW fitler. Anyone tried this? Anyone installed it themselves or should this be left to W4RT? Thanks in advance.

    As it comes from the factory, the IC-718 has two filters in the second IF.  The first, FI-1301, is 6kHz wide and in all modes, including AM, the signal passes through it.

    The second, FI-611 (also know as the Murata) is 2.4 kHz wide.  In SSB, CW, and RTTY the signal passes through it, but in AM, it bypasses it.  In my opinion, the factory Murata filter is fine for SSB, but then I mostly use CW.  Then there is the optional filter position.

    If you're going to work CW, it won't be long at all before you want either the Icom FL-52a (500 Hz) or the InRad 400 Hz filter (set up in the power-up menu as a FL-52a) in the optional filter position.  Both companies also offer a 250 Hz filter, and while better for contesting, where you can use the narrow width, it requires a little slower tuning not to miss calls when just ragchewing.  I used the InRad 400 Hz, about $25 cheaper, a little narrower, and with steeper sides than the FL-52a.  

    Once you install it, you can set the power-up menu for it and have a N (narrow) filter option on CW and RTTY.  When N is selected in those modes, the signal goes through the optional filter rather than the 2.4 kHz Murata.

    I have no experience with the W4RT filters.

    Congrats on ordering the 718. You wont be disappointed, again it's a great value. Antenna's are so very important and you may want to try a few designs to see what works well in your situation.

    The first time I listtened to a 718 was at a dealer in the middle of a industrial/commercial area. I live in more of a rural area and there was much better performance in my QTH. No I am improving my antennas and have had some excellent dx along with great signal reports. Good antennas are key.

    I also have the Inrad 400 cw filter and it helps a lot. This is a great site if you have questions. There are also a number of Yahoo groups around the IC-718 users. There you can be very specific with questions and get answers from users around the world.

    Good luck & enjoy!

    I have a 718 and it is one of the best value for money rigs around. If you are happy to have a rig without FM it will suit you fine. The menu system  in the 718 is quite easy to follow and it is a very user friendly tranceiver. After owning the 718 for over two yearsI wouldn't part with it. Recently I decided to replace my old Yaesu vhf and uhf rigs with a radio that would cover everything so decided to get a 706mk2G but will keep the 718 because it works so well.

    That excuse worked for me. I guess it worked for you also. The first thing your going to notice, at least on SSB, is the DSP filter option in receive. Once you've used it there will be no going back to older radios.

    I have a 735, but not a 718.
    I can tell you, however, that the 718 looks a little less intimidating than the 735, and is more compact.

    My 735 was made in 1987, and it still works great!
