Re: [softrock40] Softrock and TRX sharing antena
- As with any new circuit, check your work in stages. Connect a dummy load in place of the antenna and then check the relay to make sure shorts the Softrock antenna to ground while when the FT-1000D is keyed. You should connect the Softrock only after you have verified that the circuit works the way you expect.Hi Jakub,You are correct, the circuit as show will not work if the TX signal goes low on transmit. I'm not familiar with the FT-1000D, but maybe the TX-GND signal is enough to directly drive the relay? If so, then you could eliminate Q1 (and the associated components) and connect the TX-GND signal where the Q1-C was connected. Check the spec on your FT-1000D, and on the relay you choose, to make sure that the FT-1000D can sink enough current.
I have not noticed any problems with the switching time of the relay I used. However, the TS-440 may drive the XMIT signal high slightly before enabling the actual RF.73,...jerry

thanks for the info,
this with you using a TS-440 and PTT took control of the REMOTE jack,
I have a FT-1000D and in me there is no such slot ...I'm thinking that I could use the TX GND jack
(it is shortened when pressing PTT) and PTT output normally I use for controlling my PA ....
I do not know if I can do it?
Maybe someone more experienced to terminate .....?
does not want to make a mistake for some not to damage Softrock ...

p.s. I think that with such an important role in the system meet the relays .... I think they must have fast response and the delay that followed the OMRON is fast?
I have a similar setup and here is what is working for me:

I have a question if someone could help me in this topic
Well, I have my desktop radio FT-1000D as well as Softrock I use,
and I would like at the same time have the opportunity to listen to the same
on one and the other radio (FT-1000 and Softrock) and when I want to
to the FT-1000D is want him to Softrock was automatically disconnect and
shorted to ground
if anyone has a proven systems and could help me?
