EE123: Digital Signal Processing

Spring, 2017

Radio Tips:

  • How to talk:

    • Hold the radio about 4 inches away from your mouth, antenna in vertical position.

    • Press the Push-to-Talk (PTT) button. Wait 1 second before speaking

    • Speak clearly, slowly, but not too loud so the voice is not overmodulated

    • Wait 1 second before releasing the PTT

  • Comprehensive instruction manual for the Baofeng UV-5R is found Here

  • About the only way to damage your radio is to transmit (press the side PTT button) with out the antenna connected.

  • Switch between low(2W) and high(4W) power: short press # key. Letter L will show up on the screen.

  • Repeater reverse mode: short press on * key. Letter R will show up on screen. In this mode, the repeater input and output frequencies are switched. It is used to find out if the person you are talking to, is within simplex range.

  • Voice activation mode (VOX): press menue -> press 4 to enter VOX menue. Press menue -> use arrows to set VOX level. We will use VOX in order to transmit using the computer.
    DONT FORGET TO TURN OFF VOX or the entire bay are will hear your conversations!

General Operating Tips:

  • Phonetic Alphabet

  • Our class simplex frequency is 146.430 (ch-4), monitor it for EE123 traffic

  • You are well aware of this by now, but it's important enough to merit repeating. Your first and last transmission should always contain your call sign. During an extended contact (QSO), you also need to ID with your callsign at least every 10 minutes.

Some frequencies of interest if you would like to talk to other Hams:

  • SMPLX2M (ch-1) is 146.520 MHz, the national 2m simplex calling frequency, SMPLX446 (ch-2) is 446.000 MHz. You can most always directly reach fellow hams by transmitting “CQ CQ CQ followed by your callsign” when at higher elevations on this frequencies, especially 146.520 MHz.

  • WW6BAY (ch-43,ch-44) is a linked repeater system covering all of the bay area. It's 2m, 70cm south bay and 70cm north bay are listed in your radios with the 2, S and N suffixes respectively. It is owned and operated by many local engineers.

  • N6QOP (ch-23) is a phantastic repeater which is part of the CARLA system and has coverage of the Berkeley area as well as east of the hills. Use CARLA (ch-49) to link to the entire system

  • WA6HAM is the Contra Costa ARC repeater. Very good coverage in the east bay
