My R-390A is coming along nicely. I sounds great and is performing nicely on
most bands. Now, I want to tweak the RF alignment on the 2 mhz and 3 mhz bands.
Here are my questions:
1. According to the manual, I should set the bandwidth to 8 khz. Is that
correct? I would think it should be adjusted more narrowly.
2. The output meter is adjusted to the diode load. The signal generator is
adjusted to give an output of -3 to -7 V. Is that on the -DC range?
3. Do I set the signal generator for modulated or unmodulated output?
4. Would there be any great problem if I adjusted the slugs and trimmers to WWV
on the 2 mhz band and CHU on the 3 mhz band without a signal generator?
As always, thanks!
