    I would like to ask for some help specifically from hams in the northeastern part of Ohio. A friend of mine would like to be able to talk simplex on 440 and the bandplan is useless for this question (other than specifying 446.00MHz as the national simplex calling freq)
    Can someone tell me what the acceptable simplex frequencies are on 70cm in the northeast Ohio area? All the bandplan says is that frequencies between 445.00-447.00 are useable as long as there isn't a repeater using that output in your area.
    Thanks very much in advance.

    The SERA bandplan (the coordinating body for the southeast, not including Ohio [which isn't in the southeast of course]) specifies the following 70cm FM simplex frequencies

    445.9125 # 445.9250 # 445.9375 # 445.9500 # 445.9625 # 445.9750 # 445.9875 # 446.0000
    446.0125 # 446.0250 # 446.0375 # 446.0500 # 446.0625 # 446.0750 # 446.0875 # 446.1000
    446.1125 # 446.1250 # 446.1375 # 446.1500 # 446.1625 # 446.1750

    I expect that those (especially the ones near 446.0) are probably clear in Ohio as well.

    446.000 MHz is the "national FM calling frequency" and probably should be tried first. There just usually isn't that much activity on 70 cm FM simplex and thus most, if not all, of the other frequencies are not going to be monitored. As for moving a QSO from the calling frequency, then the 25 KHz channel steps are the most used.

    Of course SSB and CW have different calling frequencies.

    Sixmeters,

    I am too in northeast Ohio. I am in Hubbard, 1 Mi from the Penn Ohio line and just a couple miles out of Youngstown. I hear very little on 440 simplex. Actually, the 440 repeaters we have locally are very underutilized.
    If anything try 446.000 or a scan of the band. If you want to run a few tests and have a good location and antennas, come to 147.515 simplex. There are quite a few of us in the Youngstown Oh/ Sharon PA area that operate on this frequency, and a few of us sit on hilltops. Come check us out some night. We'd be more than happy to have you join us!
    get a signal.......

    Do not use 445.975 in Ohio. Someone thought it was a good idea to put their wide area repeater's link frequency 1 full channel away from the national FM calling frequency, WITHOUT PL no less. Anyway, you might have trouble if you use that frequency.

    If you monitor 445.975 MHz and don't hear anything after a while, why not go ahead and use it? There may not be any interference, and anyway, don't we all have equal rights to any frequency (within license class limits, of course)?

    I guess you could, but keep in mind that you would be heard on the output of the linked repeaters.

    Good point, but it seems to me that link frequencies should be documented somewhere, so folks don&#39;t have to find out about it by word-of-mouth. Also, if the traffic on the linked repeaters is so low-volume that you don&#39;t hear anything after monitoring for a while, seems like they&#39;re unnecessarily eating up bandwidth.

    Not really expecting a resolution here, merely observing and thinking about it.
