EXERCISING COMMUNICATIONS ON SSB SIMPLEX

Suggested Simplex frequency for SSB operation is 144.225 MHz plus or minus 10 khz in case the frequency is in use.

 

First MoCo SSB Simplex Exercise scheduled for Wednesday 6/24/15 at about 7:50 pm PST, following the ARES net.

 

SSB SIMPLEX on VHF or UHF bands can support communication over surprising distances and over rough terrain. [Reference: Intro to EMCOMM, ARRL Publication, 2011]

 

Here are ways to improve simplex range:

 

• Use an antenna with greater gain

• Move the antenna away from obstructions

• Use a directional antenna

• Increase antenna height

• Increase transmitter output power as a last resort

 

 

Here is a suggested site on helpful hints for choosing SSB Simplex frequencies, by K0NR http://www.k0nr.com/rwitte/2m_frequencies.html
