Our 2-meter and 70 cm (146.700(-) and 448.900(-) MHz with a 100 Hz PL Tone) WØDK repeaters are located in Boulder and can generally be accessed from the Wyoming border in the north to Monument Hill (near Colorado Springs) in the south. Coverage is primarily to the east of the Rockies Front Range. BARC also maintains an IRLP/Echolink repeater on 146.610 (-) 100 Hz PL which is located on Eagle Ridge in Lyons (see below).

The repeaters are maintained by a small group of dedicated volunteers headed by Dan (NØHF). If you need to report any performance or operational problems, please send a kindly worded email as follows:

BARC's own IRLP node # 7007 on 146.610 (-) (100 Hz tone) repeater


The aim of the IRLP project is to reliably and inexpensively link amateur radio systems without the use of RF links, leased lines, or satellites.

The IRLP uses Voice-Over-IP (VoIP) custom software and hardware. Coupled with the power of the Internet, IRLP links our BARC 146.610(-) 100 Hz tone repeater to the world.

IRLP operates a network of dedicated servers and nodes offering very stable worldwide voice communications between hundreds of towns and cities. All this with unsurpassed uptimes and the full dynamic range of telephone quality audio.
