Transmitter Hunt Practice Saturday 9/21

Weather Update

Despite rain in the morning, the activity is go for a 1:00 PM start time.


There was a lot of interest in the hidden transmitter hunt last week. At our monthly meeting, there were requests for a program on the final few meters of searching, covering both theory and practice. Accordingly, at 1:00 PM CDT on Saturday, September 21st we will have a hidden transmitter hunt (2-meter) practice session in Tarnhill Park (98th St. and Little Rd.) in Bloomington. The practice session will focus on on-foot techniques and relatively simple equipment. Bring what transmitter hunting equipment you have; there will be some extra gear available for use.

This is a fair-weather activity, and a final go/no-go decision will be made by 7 AM CDT on Saturday 9/21 and propagated on the BARA website post for this event.

Hidden Transmitter Hunt Thursday 8/29

With a stretch of nice weather in the forecast, it’s time to dust off the transmitter hunting gear! This Thursday (8/29/19), the Bloomington Amateur Radio Association will be hosting a transmitter hunt, beginning at 6:30 PM at Bloomington Civic Plaza from the parking lot on the west side of the building (near the southwest entrance).

The field of play will be the City of Bloomington, bounded on the west by US HWY 169, to the north by I-494, and to the south and east by the Minnesota River.

Format: Two hidden transmitters; one 500 mW to 1 W, the other 10-20 mW and in the general vicinity of the stronger transmitter. The transmitters will be on alternate 1-minute transmit windows.

Accessibility: A vehicle will be required for finding the transmitters, but at-home operators (in Bloomington and possibly surrounding municipalities) with omnidirectional or directional antennas can still contribute with coordinated hunting (see Resources below for tips from WB4APR). On-foot hunting is expected to take up to a mile of walking on sidewalks, dirt/grass paths, or over cut grass.

Difficulty: This is intended to be a beginner-friendly event, and those without directional antennas are encouraged to take part in a coordinated hunt (see Resources below). With sunset at 7:56 PM, the event will be complete around 8:00–8:15 PM.

Two hidden transmitters: 146.565 MHz FM
Safety and administrative: 147.090 MHz, +600 kHz, no tone, analog FM (KD0CL VHF repeater)
Coordinated hunting: 443.175 MHz, +5 MHz, DCS 047 (TX and RX), analog FM (KD0CL UHF repeater; repeater is Yaesu C4FM capable, but please use analog for this event)

February Meeting Cancelled, Replaced by Net

With the bad weather and road conditions, there will be no in-person meeting for the Bloomington Amateur Radio Association tonight. At 7:30 PM, we will instead host a net on the 147.090 (+600 kHz, no tone) repeater.

If there is interest after the net on our primary repeater, we may move to the 443.175 (+5 MHz, DCS 047) repeater, although its coverage is not as large.

The next in-person meeting will be Tuesday, March 5, 2019.
