Worked ‘em?  How about a QSL?

The ARRL 8th area qsl bureau has just sent out one of their periodic shipments of DX cards to all their letter managers. I am the manager for the E letter, so if your callsign has 8E in it, your cards go via me. I received about 1000 cards to sort and mail to all those who have envelopes on file here. Some call signs get special treatment, like K8ES (our club callsign), which I deliver in person at a club meeting. We received 4 cards this time. And then there are a few odd balls like K8EHB who received one. If there are any other 8E calls out there who receive DX cards let me know. If you contact DX stations, some of them WILL send you QSL cards via the bureau.  You cannot stop it. And they will generally expect to receive a card in return. If you want to get your cards, you must send self-addressed, stamped envelopes to your letter manager.

Radio Data Broadcast System Time Foibles

FDBS is a system used by FM broadcast stations to transmit extra data. You may have noticed this in your car radio, when the display shows things like call letters, format (news, sports, talk, rock etc), song titles and performer etc. FDBS is a subcarrier that can send about 1 kilobit/sec of data, and that is how the display gets its information. FDBS also transmits the local time (supposedly). I have a weather radio that happens to also receive FM broadcast, and it has the capability to set its clock display automatically, based in the FDBS information it receives from the station it is tuned to. I decided to turn this feature on, so my weather radio would always display the correct time. First I tried WOSU-FM 89.7 MHz, the OSU station.  After several days, the time was NEVER set. I finally concluded that WOSU is not transmitting the time at all.  Disappointing, since I thought they were a technology leader etc. Next I tried the the Delaware station WVMX on 107.9 MHz.  It set my clock immediately, but 26 minutes SLOW.  I let it run for a long time but it always stayed at 26 minutes slow.  Bummer.  I was beginning to think my radio was not working correctly.  But the radio allows you to program in 3 different FM stations, so in desperation I tried WMMR on 93.3 MHz.   It also set my clock immediately, and I cheered when it set the time to within  a minute!!  It would seem that the RDBS time signals are not all they might be, and one wonders if anyone at the stations is paying any attention to this. Does anybody know anything about this? - Bob W8ERD A CW Bug If you remember one of my hobbies is collecting pictures of ladybug shells because I think they are trying to communicate with us using Morse code. All I can find are dits... until now -Wally, W8WLK
