    Just logged my 2nd ever Cayman Islands station, thanks to Rabbit Ears RDS Autologger. ZFKX-FM 107.1 in George Town. Double checked with the RDS Spy logs...sure enough, "X107.1" decoded with a PI of 4F29. 1,021 miles for Cayman #2. screenshot-rabbitears.info-2021-08-04-13-12-17-419 ZFKX 107 1 in George Town.png

    Why should you consider adding an automated RDS auto-logger from Rabbit Ears to your shack? I can think of a few good reasons. The photo below is from not even a month's worth of having the system running. Many of these receptions came when I was at work, out of town, or doing family activities--a lot of new ones in my logbook thanks to Russ.

    The great thing about the Rabbit Ears implementation of RDS Auto logging is that it calculates the "I-Heart Radio" variation for you. And it "error checks" by comparing your decodes to the frequency of reception. If they don't match, it doesn't report the reception. Virtually eliminates false decodes. There is a version of this for both SDR Sharp (#SDR) and SDR Console that will auto-scan. See the top of this thread for details.

    You can try substituting each other digit for the 1 in the first digit of the PI code. For example, if you log 18C6 on 105.9 you'll find it converts to KDIK. There is no KDIK.

    Try 28C6, 38C6, 48C6, 58C6, 68C6, 78C6, 88C6, 98C6 in a PI-to-callsign converter. (I have one on http://www.w9wi.com/articles/rds.html) You'll get:
    28C6 KJJY (92.5, Des Moines IA)
    38C6 KPLM (106.1 Palm Springs CA)
    48C6 KVNA (100.1 Flagstaff AZ)
    58C6 WBOO (ch. 50 Elk Mound WI)
    68C6 WHQC (96.1 Shelby NC)
    78C6 WNRQ (105.9 Nashville)
    88C6 WTTE (ch. 28 Columbus OH)
    98C6 WZUS (100.9 Macon IL)
    You can reasonably presume you had Nashville.

    (this one was really unusual in that every substitute PI actually exists!)
    Don't forget about A8C6 - WQSK (97.5 Madison ME)

Next question is, do I need to continually scan the FM band when I'm not actively DXing because I haven't figured out how to do that in SDR Console, only in SDRUno.?

    I would love to participate. I have an SDRPlay RSP1A, although I'm on a Mac using Gqrx.

    Updated my computer to the latest version of Windows 10 last night...this morning it still hadn't finished the install, and I had to begin again. Ended up missing a big part of the opening this morning with the auto-logger. Still put two news ones in the log.

    After running now for two weeks, including one great opening on June 28th, I can say that this tool is nothing short of incredible. During that opening, I was able to dedicate the Airspy HF+ SDR to the Rabbit Ears auto-logging of RDS stations--which netted dozens of new receptions for the log. At the same time, I also recorded an 8mhz I/O file using the AirSpy R2 for later review, and DX'ed LIVE using the Elad SDR. Russ has created something really special for FM DX'ers here.

    Easy to get started, and can be done using an inexpensive RTL SDR (Dongle) for about $20 bucks married to a simple outdoor antenna including a dipole. Let it run 24/7 and you'll be amazed at the new stations that you'll log.

    Some suggestions for improvement:

    It would be great if the software could alert you when you log "All Time New Ones." By flagging these for say 72 hours. After you've logged a lot of stations, it's not easy to spot when a brand new station is logged for the first time. Adding this "Flag" would really make the tool more useful.

    After a big opening, the new stations don't always disappear from the "logged in the last 24 hours" section but instead linger. This can clutter the map and make the tool less useful.

    Minor things to be sure...love this tool. We need more FM DX'ers from the West in USA and Canada. What are you waiting for? Join the fun today!

    Up and running now in Alabama. We need more stations out West. Easy and inexpensive project...join in on the fun.

    Rick-- To download the software, you need to contact Russ directly via e-mail. He will assign a unique user number for you, and send you links to get you started. Let him know if you want to run SDRSharp (#SDR) or SDRConsole or if like me, you want to try both.

    He can be reached here:

    If you're interested in participating, contact me at XXXX_vhf@hotmail.com Substitute XXXX with my ham radio call sign KB8U

    It will be great to have you join us. Super fun!

    Note that Russ has a version of this for both SDRSharp (#SDR) and for SDRConsole. E-mail him for details.

    Working on getting this setup for my site in Birmingham.

    I don't think you're talking about using the RabbitEars auto logger, just RDS in general. Most iHeart stations use a 1 as the first digit of the PI code, which makes them show up with K callsigns. For example, 93.3 WSNE sends out the code 1586, while the correct code for their call letters would be 8586, The RabbitEars auto logger is somehow set up to understand these codes for the iHeart stations near me, possibly using the WTFDA database.

    Larry--so excited to see this! I've been using SDR Sharp along with the RDS Data Logger plug in for about five years...and it's put lots of new stations in the logbook by allowing it to run unattended and then looking up decodes later in the WTFDA database. This takes the same concept to an entirely new level.

    Now, I'm strictly a Windows guy, so the idea of "compiling packages", etc. is a little scary for me--but I have the hardware and software configured and running now. Can't wait to add Birmingham, AL to the list of sites. This is super exciting. We need these all over the country--it would be like our very own e-skip detection network! Hope lots of FM DX'ers will join in.

    Thanks for all that you do for the hobby.

    73,
