Fox Hunting Course at Boston ARC Proposed at Artisans Asylum, Allston

Chris LaRosee, KC1TSA, writes on the Boston ARC mailing list:
 
I’m planning to introduce a 4-weekend RF Foxhunting course and plan to pitch the idea tomorrow at our meeting. The course aims to dive into RF foxhunting, mixing theory with hands-on practice. It’s a chance to sharpen our skills and potentially draw in new faces to the hobby. Here’s the breakdown:
 
– **Week 1**: I’ll cover the basics—what foxhunting is, the gear we need, and understanding RF propagation with a field demo of polar patterns. 
– **Week 2**: Shirley KE1L will guide us in building our own directional antennas. It’s a DIY project with immediate practical use.
– **Week 3**: Liam Platt, an electrical engineer, will help us build diode-based attenuators. We’ve got custom PCBs and all parts ready.
– **Week 4**: We wrap up with a real foxhunt, using the gear we’ve built.
 
**Costs & Materials**: We’re looking at around $132 per person to cover materials (antennas, attenuators, radios) if we have 5 people join. This includes everything they need to start, with a bit of margin for the unexpected. 
 
**Goals**: Beyond the fun and learning, this could be a great way to get more people into RF and ham radio. It’s hands-on, it’s outdoors, and it ends with everyone actually using what they’ve built.
 
I’ll go into more detail during our meeting tomorrow, but wanted to give you a heads-up. Looking forward to making this happen!

KC1TSA Fox Deployed, Allston-Brighton Neighborhood of Boston, February 3, 2024

The KC1TSA fox is now deployed.

Frequency: 446.025 MHz

Location: Lower Allston/Brighton Neighborhood of Boston

Transmission Schedule: Every 30 seconds Sunday (2/4) starting 5AM and lasting until10PM

Disclaimer: The fox is NOT on private/residential, church, or school property. Looking in these places is not endorsed and discouraged.  Further, I am not providing a starting location where the signal can be heard, but I will say that the fox is operating on pretty high power (UV5R Based), and driving around the area or walking to high places should get you to the signal.

Beginners: text me for additional hints, such as the best parking place or if you wish to borrow a directional antenna.

Happy Hunting,

W1MJ Fox is Out, Belmont, October 22, 2023

Eliot Mayer, W1MJ, writes on the NEMassFoxHunters list at 2:50 PM on October 22, 2023:

W1MJ fox now available on 147.450 MHz, in same On Demand mode as K1MJC fox; just ask it to please transmit.  This one will transmit for 1 hour, then you have to ask again.

From Mike’s fox, take trail in left rear corner of Rock Meadow.  It goes to Beaver Brook North, and the direct route to my fox is no more than 15 minutes from there.

Good luck finding both foxes.

K1MJC Fox is Radio Active, Belmont, October 22, 2023

Mike Cormier, K1MJC, writes on the NEMassFoxHunters list at 10:27 AM on October 22, 2023:

Well, the new K1MJC fox is out!
 
It was designed by Eliot W1MJ, and this one has an on-demand feature.
 
All you have to do, is transmit on the fox frequency for about two seconds (Say anything, but should include your callsign), and the fox will begin transmitting various messages for 30 minutes. 
 
When the 30 minutes has expired, the last message will encourage you to make a voice request for more.  (just repeat what you did to get it started in the beginning).

 
I don’t know how long the battery will last on this fox, so I plan on leaving it out for quite a while. it’s transmitting on the fox frequency of 147.540MHz 
 
It’s in a conservation area in Belmont, the RockMeadow conservation area.
 
There is a log with it, I would appreciate if you would sign it, however if you just want to send a reply to this I/O group that’s fine as well.
 
NOTE:
 
Eliot W1MJ, will be placing his out later today in the beaver book reservation. He will be on a different frequency which he will announce and they won’t be too far apart in physical distance so you can hunt both foxes if you wish. 
 
His foxes the same as mine, it has the on-demand feature just as mine does and his however should transmit for about an hour before it requests you to restart it. I’ll let him tell you all about it when he makes his announcement.

Unfortunate news, decided to check on the K1MJC fox and discovered that someone had tried to steal it. However, the safety restraints saved it.

 

I will have to take it home and perhaps make some repairs and I’m not sure whether I’ll be putting it out again for the holiday tomorrow; sorry to all those who had plans to go look for it tomorrow.

Double Fox Hunt On the Air in Belmont, September 1, 2023

Eliot Mayer, W1MJ, writes on the NEMassFoxHunters list at 11:01 AM on September 3, 2023:

Due to technical difficulties, the double fox hunt in Beverly has been terminated early.

This was Mike’s first deployment of this new fox design, and it is likely that the low-battery cutoff setting was too high for his battery.  My fox became intermittent, apparently due to a bad cable going to the radio (or, hopefully not, a bad jack in the radio). 

We will address these issues and try again.  For now, go find the W1MWS fox in North Chelmsford.

 

Eliot Mayer, W1MJ, writes on the NEMassFoxHunters list at 6:00 PM on September 1, 2023:

K1MJC and I have both put foxes on the air in the Rock Meadow Conservation Area in Belmont, MA for the holiday weekend. 

Map and directions from Google Maps:  https://goo.gl/maps/6sYA2FXTKBXSdJXv7

Both foxes transmit once per minute between the hours of 8:00 AM to 8:00 PM daily.  They will be on the air until 5:00 PM on Monday, Labor Day.

The K1MJC fox is on 147.54 MHz, and has a log book to sign when you find it  

The W1MJ fox is in 147.57 MHz, and has no log book; please email your report to fox@w1mj.com.

Finally got a chance to deploy my fox.  Too much rain this summer.  My favorite spot, Hartwell Family Memorial Preserve in Littleton.  Freq 146.565 MHz with a 20 second voice ID every minute.  Please sign the log when found.  I doubled up the battery, so should run until at least next week.

W1MJ “Fox 2” On the Air, Waltham, July 30, 2023

Eliot Mayer, W1MJ, writes on the NEMassFoxHunters list on July 30, 2023 at 10:09 AM:

The updated W1MJ fox is on the air from Beaver Brook Reservation North in Waltham, MA. It makes a transmission on 147.54 MHz every 60 seconds between the hours of 8:00 AM and 8:00PM daily.

Parking is available at Rock Meadow on Mill St in Belmont and at Elsie Turner Field in Waltham.

This second-generation fox is still running a Baofeng UV-5R at full power (4 watts), but has a few new features:

It conserves battery power by only transmitting during scheduled daytime hours (above).
It periodically announces its battery voltage, and will stop transmitting if the battery goes too low.
The messages start to repeat every 20 minutes (vs. 10 minutes in original fox)

I plan to retrieve the fox after 5 PM on Wednesday (August 2).

There will be TWO foxes – one manned by KB1CNB, Skip, and the second manned by N1KJS, Kevin’s Blue Toyota pickup, MA reg S196.

Check-ins will begin at 9:45 am on the BCRA repeater, 145.150 MHz PL 123. Chat and help on the repeater also.

The hunt will last until 2:00 pm or until all checked-in participants have found the transmitters, whichever comes first.

The Fox1 (in Skip’s vehicle, a blue/grey Jeep Commander marked BCRA) will be in a public place and be manned at all times. When you have found the fox, your time and order of arrival will be recorded, and a personalized certificate will be emailed to each participant.

The Fox2 (in Kevin’s vehicle, Blue Toyota Picket, MA reg S196 has a BCRA sign) will be in a public place and will be manned. When you find the fox, Kevin will record the time and your call sign and report that to Skip.

Participants are encouraged to work in teams and are asked to drive carefully and observe all applicable guidelines, both from the FCC and the state & local governments. Since participants are receiving only (except for radio check-ins), an amateur radio license is not required.

Email questions to Skip at kb1cnb@bcra.club or text to 774-644-3469. After the hunt, your comments, impressions, and suggestions will be welcome!

Join us and have some good amateur radio fun!
