Dear,
I have a ft1000mp mkV in use for two months now and I am confused abt =
the amp swiching capabilities.
The manual states (page 12) that : .... The TX GND jack on the =
transceiver rear panel is connected to an internal relay, for non-QSK =
T/R swithcing of lineair amplifiers that use AC switching voltage or DC =
voltage greater than +15V, negative DC voltage of any kind (such as the =
HEATH SB220/SB221 models) or if they are required to sink more than =
100mA for T/R switching. A schematic .....
With the relay enabled, the Mark V can support non QSK-switching =
voltages up to 100 VAC @ 500ma or DC voltage up to 60V@200mA.
I want to switch a mentioned SB220 rated at 125VDC@80mA. =20
The manual is quite confusing on this subject first they mention the =
SB220 and later the relay can only switch 60VDC.
But there is another subject that I have no answer on it :
The ft1000mp uses a mechanical relay part nr. RL1004 AG4013 and the =
manual states that this relay is capable of switching 125V@500mA or =
220V@300mA AC or DC . (found in the technical overview on VA3CR =
website)
The mark V uses the same relay RL1004 AG40213 ! (found on the =
schematic of my mark V).
Any explanation of the switching difference ?=20
