XV144 input level selection

[johnny-52]

Hi Group,

The transverter output level of my IC7800 is 22mv.  Could any of you advise which input level I should select for the XV144? 1 mW or 251 mW?

TNX & 73

Assuming you meant 22 mW, you should indeed use the 251 mW setting of
the jumpers. The 1 mW setting is for 1 mW maximim. You'll be able to
use the input level control to tweak the transverter to full output
for your drive level.

Johnny,

Re-check that output level because it seems quite low.  22mV into a 50 ohm
load is only 9.7 uW power.  I would expect something more on the order of 1
mW and upward.

Hi Don,

I recheck the manual of my ICOM IC7800.  It said a transverter level of
-20dBm or 22mV.

Is -20dBm equivalent to 22mv?  Or is there a mis-print in the ICOM Manual?

Hi Don,

>From page 3, specifications, of the XV144 Owner manual, the I.F. iput power
range is from -20dBm to +39dBm.

According to operation manul of IC7800, the transverter terminal output
level is -20dBm (or 22mV).

Does this mean that I.F. output of my IC7800 can still drive the XV144 to
the designed power level of 20 watts?

Looking for your advice.

TNX & 73
