On the 22nd I wrote to the group to ask for some help in trying to find the reason why I was having a serious problem tuning PSK with the 746 because I could not adjust the RF power to remove the ALC markers.
What was so mysterious was that I found it impossible to show no ALC on 20 metres and surprising to me, prior to this problem, the ALC markers could be removed by increasing the RF power, rather than reducing it. Why is this ? Can someone tell me ? While I was having this difficulty I was still able to tune up properly on 30, 40, and 80 metres and having been told that the soundboard could not recognise any differences in frequencies why was I having this problem ? For two days now I've been trying to reason why, but then I found I couldn't tune 17 metres, then 30 metres, then 40, and finally only 80 could be tuned. So I pulled out all the cables and found that a short cable which is permanently plugged into ACC1 had a ground wire which was now almost disconnected from the pin and when I connected the ACC1 cable proper the problem now seems to be solved, but has caused me concern in another way. When transmitting on some frequencies the sound of PSK could be heard from inside the computer, but now I can hear the sound coming from the 746, and not the PC. Is this harmful to the rig? Is the sound only in the speaker ? It can be heard with the audio off.Can someone advise me that it will not be creating a problem in the innards of the 746.
