146.520 MHz FM Simplex

Aloha!

There is a small group of us on Kauai that talk on "520" and keep it active. We recognize the fact that 146.520 MHz is the, "National Simplex Calling Frequency" according to the ARRL bandplan. However, this area is one of the few areas in the country where you can actually find somebody on "520" if you throw out a call. Based on feedback and discussions we've had, most hams think it's a good thing that we keep it active. There's almost always someone listening to 146.520 MHz and we're usually very willing to give signal reports, help visitors to our island with directions and information.

We use simplex 146.520 MHz to keep in practice with simplex mode of operation should our island repeaters stop operating. Contacts have been made between islands using simplex. Recently we started to keep a log of simplex contacts on the website for future reference should we need to operate simplex mode. Click on Simplex Log to check posted activities.

So join us on 146.520 MHz simplex, it is a lot of fun, and if you haven't done much of it, give it a try. Mahalo!

73 and Aloha

2 METER SIMPLEX CHANNELS

SIMPLEX FM radiotelephone “channels” from the ARRL band plan. The phonetic designators and the designated uses were added some years ago in the Sacramento Valley Section and have been adopted by others.

147.42 MHz has been promoted as a national ARES/Red Cross frequency. (It was chosen for its ease to remember since 47.42 MHz is the National American Red Cross low-band frequency.) The object is to have a common VHF simplex frequency for all ARC personnel. Example: An ARC DSHR worker, who is also a licensed amateur, arrives in a disaster area. He/she can go to 147.42 MHz and (within range), contact an ARES/ARC unit.

147.57 MHz has been designated and in use for SAR in some areas. Just as 155.16 MHz is the NASAR frequency, 147.57 MHz may be worth promoting as a national SAR amateur radio simplex frequency.
