Guest Speaker: Don VE3IXJ
Topic: The Power of the HT Repeater.

Don demonstrated a simplex repeater, Surecom SR-112, costing approximately $80 Cdn bought on eBay from China. It attaches to the mic/speaker of the HT radio. On receive it records the audio, then re-transmits the recorded audio. It is a very simple solution for use in a local environment. Then Don demonstrated a crossband repeater, Surecom SR-628, costing approximately $90Cdn. The lightweight and inexpensive repeater could be set up easily and quickly in a typical emergency where simplex operation might be ineffective.

The crossband repeater was connected to an inexpensive Chinese radio capable of crossband. Anything received on VHF was retransmitted on UHF, and anything received on UHF was retransmitted on VHF. To extend the range, Don added a second crossband repeater/radio combination and then a third repeater/radio combination. From end to end a typical path would be VHF Freq#1 – repeater – UHF Freq#2 – repeater – VHF Freq#3 – repeater – UHF Freq#4.

A conversation could be heard on any frequency along the path. A radio in the middle could transmit on UHF Freq#2 or VHF Freq#3 and be heard at both ends of the path on VHF Freq#1 and UHF Freq#4.
