- First of all, thanks for all the people who sent me email on the DJF1T
- mods. I've tried it and it works!!
- Here is the summary:
-
- Open the radio and place it face down with the BNC jack up, and locate
- two jumper wires on the lower right hand corners of the set. The red jumper is
- for extended receive, and the blue(I think it is blue?) jumper is for extended
- transmit. Just cut/unsolder the red jumper for extended receive, blue for
- extended transmit, or both jumpers if you want both.
-
- Push the F button while turning the set on to reset radio to factory
- defaults. The extended receive (AM aircraft) can be activated by pressing
- the B button on the keypad. (If you cut both jumpers) A letter A will show
- up on the LCD indicating that radio is in the AM mode. To go back to FM, just
- press B again. I think B just activates a second VFO in the radio, since radio
- retains the AM frequency when toggle in and out of te AM mode. My serial number
- is 8221, so this mod should work for radio with serial numbers close to mine.
- The radio will not transmit in AM mode, but it will transmit up to the ~160MHz
- range. I can say that it works up to the weather band frequencies. I've checked
- it by transmitting on 162MHz to a FT-415 at the lowest power setting inside
- an enclosed screen room.
-
- Try this mod at your own risk!
-
- A few words about the radio in general. I had the radio for about two days
- and I already had several IFR flights with it on board an airplane. The radio
- performed flawlessly. The fit and finish of the radio is excellent. The
- entire radio case is cast luminum, except the battery case, which is plastic.
- The only gripe I have about the radio is the battery latch. It seems to do the
- job, but looks a little flimsy. If I really sqeeze the radio HARD, I can feel a
- tiny bit of movement between the battery case and radio. But I complaint about
- the same thing about the glove compartment in my Honda....
- I prefer the what we pilots called " human engineerd" aspect of the radio. Most
- of what I use in the airplane are rarely more than two buttons away. God only
- gave me two hands a while back, and I need one to fly the airplane, and the
- other to toggle the radio controls.
- Cheers
