We bounced this idea around in the past years but I'm not sure it ever made it into the N1MM cluster list: Is there an easy way to filter the N1MM Cluster list accessible in the Telnet window, to only

You have to read the rules to be sure. But for most contests and modes, on-air communications using the bands and modes of the contest is allowed during the contest period, to arrange a move between b

Mike, for sure "SET/SKIMMER" is what we want for VE7CC clusters. But if there's lower level user-configurable parameters for deduplication I'm not aware of them. I think AR-Cluster has more user confi

Mike, if you are in front of N1MM, you can type in a callsign or prefix and look in the lower left of entry window to see the "Human readable" country name. There are a handful of calls where you need

Eric, there's various levels of checking and deduplication at each individual skimmer node, at the reversebeacon aggregator, and in the cluster software. I agree that between those three levels, that

Mike, is Window->Multipliers->Countries better for you? The prefix abbreviations used might be confusing. I think N1MM uses CTY.DAT notation which is close but not quite identical to the prefix notati

By the way, in CQWW2019, 98% of CQ's were between 21WPM and 40WPM. The highest average WPM CQ speed was D4C, at just a little more than 41WPM. There was a thread last year where several made requests

Mike, previously the VE7CC-based clusters I used, they "deduped" skims so there would only be one skim for each station every ten minutes (well, more like a couple every ten minutes). In the past week

Bob, as a US station using the call thinking about using a history file in ARRL DX, keep in mind that DX stations are very likely to change their power from year to year. They are much more likely to

Larry et al, On copper Ethernet with wired switches, using 255 in the last octet has always worked with me for broadcast on the local subnet. On Wi-Fi I have had much more variable results with 255 fo

A feature you almost certainly want to turn off in a new Windows install used for N1MM, is all USB power save modes. Some detailed instructions here: https://n1mmwp.hamdocs.com/setup/interfacing/#usb-

John, you mention several good optimizations for CQ'ers and S&P'ers F4, that I too would love to see those in the default macro files! But for WPX in particular - where it is more important than every

You're right Mike, EXCH isn't very optimal for repeating serial number only in the sprints. For CW I have this in my F6 key: F6 NR,# Hit F6 a couple times if you need to send multiple repeats. Also ke

I want to add, that when using a guest op callsign that it is best to make a database just for that callsign. That is a convenient way to not mess up the usual N1MM station settings of the usual stati

You can add leading zeroes if you feel it's a better style or helps you get the serial number across to the other guy better. Or in RTTY contests some folks believe that it's easier to "click on 001"

I open a half dozen or more contest logs every week and never ever do I bother to look at the N1MM "Start Date" :-) I don't think there's much value in the "N1MM start date" feature. Experimenting wit

John, I highly recommend PC users install Meinberg NTPD for a full-featured very stable Windows NTP solution to setting time. https://www.meinbergglobal.com/english/sw/ntp.htm But there are dozens of

Interesting configuration detail! My two cents: In a Multi-Distributed (ARRL style at least where the loggers must be networked), it is extremely likely all the PC's are on the internet to access the

Rod, I want to correct my previous response. I think you're right that the ADIF sucked in by AD1C has to have the CQ Zone to be useful. Now that I recall the process, I exported all my N1MM ADIF's to
