T-4 Sanity Check

Steve Wedge, W1ES/4 All Messages By This Member #84073 Working on a T-4 that I sold and has come back for repairs after UPS played Mad Max with it.? I can't remember if the functionality of TUNE and SSB are dependent on there NOT being an open key in the KEY jack. This makes sense merely because the TR-3 and TR-4 function that way but I can't check against my T-4X because the T-4X is a very late one that is more similar to a T-4XB (4-wafer FUNCTION switch), Anyone out there with an early T-4X or a T-4 that can verify this for me?? If I close the key (when it's inserted into the KEY connector), I can use TUNE, SSB and AM.? If the key is open, TUNE, SSB and AM don't work. If I'm correct, I can send this back to its new owner. Hopefully, UPS won't abuse it again! 73, Steve Wedge, W1ES Time flies like an arrow.? Fruit flies like a banana. Sent with secure email.

My T-4X is on the needs to be fixed list, but I can take a look tomorrow with an open key in the key jack. 73 Stan KM4HQE On 4/2/25 18:51, Steve Wedge, W1ES/4 via groups.io wrote: toggle quoted message Show quoted text Working on a T-4 that I sold and has come back for repairs after UPS played Mad Max with it.?

Steve Wedge, W1ES/4 All Messages By This Member #84088 Stan, I’ll have to check the serial of my newer one. I don’t know when Drake changed over but it was definitely late-late serial.? I now remember that they behave the way this T-4 (and all TR-3/4’s) do. Faulty old phart memory… Steve Wedge, W1ES Time flies like an arrow. Fruit flies like a banana.
