ARRL President Kay Craigie, N3KN, expects to see the list of cosponsors for the US House version of the Amateur Radio Parity Act of 2015 -- H.R. 1301 -- top 100 soon after Congress reconvenes following its August recess. As of August 27, the measure had attracted 94 cosponsors. A US Senate version of the bill -- S. 1685 -- also has been introduced. President Craigie again encouraged ARRL members to urge their congressional delegations to cosponsor the bills.

What is a Repeater?
In the world of modern communication there is an ever increasing need for providing higher outreach. The traditional portable radios offer limited coverage area. However, a dedicated transceiver can help us achieve the requisite coverage.
A repeater is essentially a communication device which acts as a link between two radio operators to cover a large area. If you need a large coverage area like your 50,000 acre ranch, city, county or even an entire state, a repeater system comes in handy.
How it Works?
It is a two-way radio frequency communication system which receives a frequency from portable two-way radios, and re-transmits it at another frequency in real-time, albeit at a higher wattage than typical portable radios. This mechanism allows repeaters to broadcast to a much wider reception spectrum. Since it is capable of both transmitting and receiving at the same time, it is also called a ‘Transceiver’.
