Recommendations
1. Means of communications outside of a cell phone such as a mobile radio.
2. Arrive with a full tank.
3. Purchase from Ebay an attenuator such as "Fox Hunt Offset Attenuator ASSEMBLED" or "NEW 0 - 82DB VARIABLE/ STEP ATTENUATOR 50 OHM for Ham Radio 
Transmitter etc-USA"
4. Have a third passenger to navigate for safety purposes while driving.
5. Teamwork is encouraged among participants. Have a plan!
6. Since we are located in a rural community, driving on unimproved roads is highly possible. Drive at your own risk.

What to bring
1. A dual band HT with a quality receiver and a signal meter. Baofeng HT will work but they do not perform well for direction finding. Look for 
dual band HT from a reputable brand such as Yaesu and Icom. Yaesu just released a new Yaesu FT-65R HT which is a great performer based on experience.
2. Doppler and other DF equipment. 
3. Implements to write with such as a clipboard, pencil, straight edge and a printout of the map for the area.
4. GPS or Compass. Most phones can simply download an app such as GPS Status to use a phone for this function.
5. There are several DF apps available for both Apple and Android such as Sig Trax. They can eliminate the paper and pencil method of drawing lines.
6. Good footwear, no sandals.
7. A hat and sunglasses.
8. Bring plenty of drinking water and snacks. First aid kit.
9. Money for lunch.
10. Smartphone or tablet.
