Any place with high elevation offers ideal conditions to test the range of a radio gear. I was in Tagaytay last week testing out the two-way radio equipment I have installed in my EcoSport. With multiple successful contacts from Tagaytay to other radio stations in Quezon City, I was able to determine that my current radio setup has an effective range of at least 70 km.
The two farthest-ever distances reached by my radio setup is (1) about 135 km, when I accidentally received a “CQ” (a call) from a station in Calapan, Mindoro, while driving along Roxas Blvd., in Manila and (2) about 210 km QSO with local stations in Baguio, while driving along NAIA X elevated highway in Pasay.
The equipment I used for these tests are as follows:
Yaesu 2900R VHF 75-watt base radio
Diamond SG7000 dual band mobile antenna (1/4-wave VHF, 6/8-wave UHF)
Diamond K33 antenna mount
Diamond SX200 SWR meter
4 meters of RG8 cable
