I have heard quite a few discussions regarding the QRP calling frequencies on the HF bands and it seems that there are some minor differences, depending upon location etc. Here then are the QRP frequencies I monitor. If you should have any amendments to them then please E-Mail me
160 METERS (Top band)
1.810 MHz (CW) - 1.910 MHz (SSB)
3.560 MHz (CW) - 3.690 MHz (SSB)
7.040 MHz (CW) - 7.090 MHz (SSB)
14.060 MHz (CW) - 14.285 MHz (SSB)
18.096 MHz (CW) - 18.130 MHz (SSB)
21.060 MHz (CW) - 21.385 MHz (SSB)
28.060 MHz (CW) - 28.360 MHz (SSB)
144.060 MHz (CW) - 144.285 MHz (SSB)
Because of the availability of cheap TV colour crystals and the inventiveness of radio amateus in general, you may also find QRP CW activity on or around 3.575 MHz.
Note that these frequencies are the EUROPEAN frequencies, there may be some differences in the USA.
