>1. As a new owner, I am curious about the Spec, Plus & Minus point of this

>(I bought it without any manual).
>
I know of no spec.
>2. I noticed that there are some 'arc' sign to be avoided. Is it for
>specific batch of production or for specific country or what (and why so)?
>
The Tune-C and bandswitch arcing are caused by a parasitic oscillation at
120MHz. Better parasitic suppressors are needed.
>3. How do I measure the 'performance' of my TL-922? (Whether it is in Top
>condition or not).
>
connect to a 50-ohm termination and measure the peak volts with a x100
probe and an oscilloscope. On SSB, the output should be around 400v
peak. (1600w) with 130w drive. Or, you could use a pep wattmeter.
>4. What is the HV, Ig does tell us? (On related to performace/ safety)
>
Ig is grid current. The HV is roughly 3000v.
>5. Is it safe to use CW switch on normal SBB QSO (to conserve engergy /
>low power mode)?
>
yes. The imd will be only slightly higher.
>6. I am using the TL-922 for Yaesu FT-847 without ALC connection, is it safe?
>
Yes. ALC is bad news.
>7. Is it safe (for my health) to work with this device (approx. within 1
>meter) for a long time (about 3-5 hours) concerning a king of rf radiation?
>
The antenna radiates, not the 922.
