FT-857, FC-40 and the AM Broadcast Band
I just installed a Yaesu FT-857 with the FC-40 tuner and a 102 inch whip in
my car. The system is working well but there are two "annoyances": 1) I like to listen to AM broadcast occasionally. Although the transceiver will tune the broadcast band, the whip is too short for this band. AM reception is very poor. Is there any way to get the FC-40 tuner to help? If the tuner would just kick in some inductance, it might help. (I imagine shortwave broadcasts have the same problem.) 2) The FC-40 seems to default to "straight-through" when you tune to a frequency segment it has never tuned before. When tuning through the 60, 40 or 20 meter bands the receiver "falls off the cliff" when leaving a previously-tuned segment and entering a new segment. The S-meter drops to S zero, and I have to push the ANT button to get reception back. This is annoying to say the least. Why doesn't the tuner retain it's match, at least during receive mode? -- Bob D. ND9B |
