Re: External PTT connection

Finally got it to work!
I saw in the manual that there was a 16 pin connector that was provided with the ic-7000 and wanted to look to see if I could use it to replace the one that I had in case the wrong pin was found to be used.
Well, the connector had a cable and an RCA plug on the end. So, I decided to try it. Plugged it into the ic-7000 and the RCA plug into the QRM-180 noise canceler. When I turned the units on, I could switch the band and the relay did not change – still in the receive mode. Then I keyed the transmit, and the QRM-180 switched to transmit mode and then back again to receive mode when the ic-7000 was back to receive mode. Exactly like it should work.
I noticed when looking at the manual that there was a user change to power pin 5 of the connector. I think that what was done and the cable (the one that I purchased from eBay that even has “7k” written on the connector) looks at pin 5 instead of pin 3. So the cable I got was an incorrect cable.
All is good and it is working to switch the QRM-180 to a bypass mode when the ic-7000 is transmitting. Now I just need to get the receive antenna connected and I can see how it works.
Thanks everybody for responding.
