- I just received an Alpha 77 Dx, modified as a two-holer, as a gift (I have very understanding friends). However, it came with a problem--it does not work. The startup light does not come on. The prev

- Paul, I note that the light on the CW/Low button came on when I pressed that button. Also, one of the meters is lit. If I am reading things right, all bulbs are 28 VDC, so I expect that the 24 volt s

- Paul, It sounds like I should hook up a transceiver and dummy load and see what happens. The CW/Low light definitely came on and stayed on when I went to CW/Low. Actually, the SSB/HI button up also f

- I am going to try to get some bulbs for the Alpha 77, two x 334 for the meter that has none, and one x 387 for the standby button that may have a burned out bulb. Can someone tell me how to access th

- Paul, I did some investigating and some testing. First, two of the three bulbs were bad. I cannot get these locally, so I have ordered both meter and switch bulbs on the internet and they will arrive

- Paul, Perhaps I was not clear in my description. I did not actually figure out what went where. There were three connections to the relay, and a continuity test showed that nothing was connected to a

- I tried to operate the relay from a 24 VDC supply, but all I ever got was a spark. No relay sound or indication that the relay had operated. I ordered a replacement HC-1 24 volt relay from Max Gain s

- Bob, The relay which seems not to work is K5, the vacuum relay. I have ordered one. The problem is that, as I check continuity, none of the poles are connected to each other. This means that the SPDT

- I received the replacement HC-1 relay from Max-Gain Systems. I purchased a used one, but it is pretty clean. I have a question. The relay came with a diode and a capacitor across the power terminals.

- I removed the old vacuum relay and put in a new (used) one. Now the exciter sees the antenna or dummy load at the output. That is the good news. I have an external swr/wattmeter, and it shows 1:1 on
