Re: Frequency Calibration


 

I'm a new FT-817 owner. I picked up mine at The Dayton Hamvention
last week. Once I got it hame and got it fired up I noticed it was
about 260-300 cycles off frequency. I concated HRO and they are
shipping me a new one.

I just received my FT817 - The radio came in excellent condition
and
turned on properly, but there were several problems on startup -
any
fixes for this, aside from sending back?

Problem Number 1:
On transmitting and receiving I noticed a frequency dependent error
in the displayed received, and transmitting frequency. Basically
the
radio display read LOWER than the actual frequency on both transmit
and receive. Using an AOR AR7030, VX5-R and an Optoelectronics
Scout
frequency counter, I found the followig:
440 Mhz: transmits and receives 15 kHz low (e.g.. to xmit on my
local 443.4 rpt, I must enter 443.415)
2 meter: 5 kHz low
10 meter: 0.650 kHz low
21 meter: 0.450 kHz low
etc.

Problem Number 2: There is something wrong with the power output on
SSB compared to AM and CW. When I transmit on AM and CW and set
the
meter to read Power Output, the meter behaves as expected, i.e.
more
bars for higher power and the battery voltage on my gel cell
decreases appropriately for high current draw (e.g. goes from 11.9
v
to 9.0 volts at high power). HOWEVER on both LSB and USB, the
Power
meter never shows any bars despite my ramping the power output up
and
down. Furthermore, the battery voltage only comes down to 11.4
volts
implying minimal current draw and minimal power output. I CAN hear
myself transmitting (off frequency) on the AR7030, so it does
transmit.

Problem Number 3:
This may not be a problem - I might just be doing something wrong -
in adjusting the microphone the manual tells you to dial up the MIC
GAIN menu, then speak and look for increasing and decreasing bars -
I
NEVER see any bar despite varying the gain from 0 to 100. I DO
hear
the effect of increasing and decreasing gain when I monitor my
transmission, but the radio just does not show it.
