Title: 15m SSB Calling Frequency
Post by: KD6NRP on July 07, 2010, 09:44:50 AM

On 10-meters, U.S. and Canadian hams use 28.400 MHz as a USB calling frequency to find one another during band openings. I often passively monitor 28.400 while I work on the computer or perform other tasks. This has allowed me to make several QSOs in recent weeks.

I've recently noticed that 15-meters is actually open part of the time, but very few stations are taking advantage of the band conditions.

Is there an established or unofficial 15m USB calling frequency that hams use to find one another when the band appears to be quiet?

If not, could somebody recommend one?

I believe 21.300 MHz is the unofficial calling frequency.

Hum. I think any frequency within your license restrictions can be a calling frequency. That is to say, just call CQ!

Absolutly...find an unoccupied freq and call CQ.  If you've been waiting for stations calling only on 28.400 and not tuning around you have been missing some great 10 m activity lately.  This past Saturday 10 was open all day and there were stations calling CQ on many freqs.  Tune around..probably why they make the tuning knob the largest knob on the rig...wink.

I think he is looking for a calling frequency to tune to while he does other things in his shack?

I usually check ten meters first ..  if its  open to anywhere,
then  15  is open for sure...

just pick a spot and call CQ.   Most hams are tuning up and down.

A fast spin of the dial will grab a noise blast on any  signal.
just go back to the area and wander back and forth  untill it comes back on.  easy to find a signal that way. even on an apparantly  dead band.

I want to set my radio to a 15m calling frequency, turn the volume up, and passively listen for activity while I do non-ham activities in the shack or elsewhere around the house.

Check your rig's manual. Most modern rigs, even HF rigs, have
scanning features. (Though no one I know uses them).
Program yours to scan up and down the Phone portion
of the 15m band. You can program it to pause for a certain
length of time, or maybe even stop on that freq.

21.080 RTTY DXpeditions are frequently here
21.110 QRP Novice/Tech Calling Freq
21.150 NCDXF/IARU beacons (STAY OFF OF THIS FREQUENCY) Many Hams rely on these beacons for propagation determination. For Details - see NCDXF/IARU International Beacon Network

i guess what you want to do is basically  impossible.
"callling frequency" was  more or less used/indicated on the  channelized bands..(xtal controlled in the day)

the HF bands it just does not exist or is there any reason to.
scanning, either manual or automatic is the only way.
Spin the dial and when you pass a strong signal you will hearit, back up and find it.

Nurp,

I used 21.350 MHz.
