    10m isn't dead

    Another day... the band is open again now... my local time of roughly noon. That VP8 is calling CQ again, and possibly making stateside contacts since he's giving reports to them. I can't "see" them, only the VP8. Made my point... no more posts on this subject. 73 my friends.

    10m isn't dead

    I hear 'ya on not making that new purchase fogdog. It's been awhile since I've seen what the band is capable of. I just made this post to point out that, if you're in or near Texas, SA comes in on 10m often... btw, I'm copying on a simple wire vertical with the base about 4ft. off the ground.

    10m isn't dead

    I'm sure what I see is "regional" so that's why I mentioned my location. Again, I see this SA pattern three to four days of the week.

    image from today's 10m FT8 rx activity.

    10m isn't dead

    I've made it a point to monitor 10m the past month or so. Most days I can see FT8 activity from South America. I'm located in Texas and am surprised to see that the US stations are seldom there to make contact with these stations. Today the dx was coming in from approx. 1900- thru 2100z and at...

    SW number station

    Yea, I don't believe it's Selcal. It's indeed a mystery. On the sdr, it's not the $1200 Elad Duo. It's the S2 (no transmit... rx only) for about half that price. After a lifetime (decades) of using radio "boxes" for SW-LW-HF reception, I took the plunge and bought the sdr, not knowing the...

    SW number station

    Does sound like Selcal... Wonder if someone else will run across this transmission at another time and see if they get the same audio I got.

    SW number station

    Ok... I managed to set up a temporary video on the 'net taken of my sdr screen (recorded) during a numbers station transmission. Yes, I know the video isn't in perfect focus, and the sounds dynamic range isn't great. The sound of the digital data is far stronger than the S/S female voice. The...

    CB Dx on the digimodes

    Lots of 27.700usb SSTV rolling in at this time... Just a "heads up" to those who wish to monitor the activity.

    SW number station

    I'm not sure how to post an audio clip on this board. As far as identifying the mode, a lot of the digital audio sounds similar... just "hissing" noise. I think viewing the audio spectrum might be more productive. Could you use a screen capture photo? I think the stations are interesting...

    SW number station

    Noticed a spanish language AM "numbers station" on 11.435mhz at 16:00utc today. I've heard them many times in the past, but it seems they are using a different format. At least this one is. First, the usual voice number readoff, but then a two-tone followed by a transmission in some digital...

    CB Dx on the digimodes

    That's cool IMD262! I'm a fairly recent observer of the activity myself. I'd like to see how many countries I can log (receive). I'm just an "swl". You might consider placing those images on one of the "photobucket" type websites for all to see. Your images are an interesting history of the...

    CB Dx on the digimodes

    Give it a try. It's been quite a while (last spring) since I was seeing the activity. Back then Europe was in every morning. By afternoon, the band shifted to south of the border. I saw quite a few very nice scans back then. It looks like the activity is picking back up. The only problem are...

    Stopping channel bleed over for locals.

    Oh yea, no regulation is an absolute no-no. Even with regulation, if the supply is too small, the voltage will "sag" on voice peaks and cause all sorts of bad waveforms into that amp.

    CB Dx on the digimodes

    Nice to see propagation supporting SSTV again on 27.700 usb (in spite of fierce ssb traffic). Germany and France appearing on the display at this time.

    Stopping channel bleed over for locals.

    CK, I would give you the nod that a ham rig with filtering is a better performer than a CB costing a lot less. So these guys should "pony up" and all buy ham rigs. The problem will go away. Case closed. ( and I am jesting with you CK ) :-)

    Stopping channel bleed over for locals.

    I don't think this is an issue of cheap CB's. I've seen some pretty good rx front ends on quality CB's. Even without "power" (especially when the stations involved have good antenna systems), the distances you describe are very close and the rx front ends of ANY equipment take a beating. Ham...

    Stopping channel bleed over for locals.

    Murphy's law postulates that the direction of the beampath needed to work that choice dx station you've been looking for will inevitably be the same beam heading of the local station you're trying to minimize signal to. ;-)

    Stopping channel bleed over for locals.

    CK gave you excellent tech tips but... Maybe I'm wrong, but it sounds to me like all of you locals are just too close to each other to expect no bleedover no matter if your "clean" or not. Let's assume you're all running power. Your 400w is one heckuva level to deal with locally. Now I doubt...

    CB Dx on the digimodes

    Thought I'd add a final note to the 11 meter digi mode post. I realize that most ops here may not have much of an interest in listening to this activity (and that's understandable) especially since we can't participate, but I find it interesting never the less. It's a challenge to dig out...
