UPDATE : Yep another blwn bias transistor - second since about April. Also appears the HV is OK at about 3145 V no load as measured with an external Fluke DVM , so metering is messed up again. What I
Dunno about the TR3/TR4/T4X series but the TR7 uses the same 4 pin mic connector as the 565 Orion (but wired differently of course so you can't use it without rewiring ) - Hank K7HP
I have an XG1 but I see now they have an XG2 which supplies a "known" signal on 3 bands (80/40/20) instead of just 40 meters, it is a little more dear at $59 - There si a littel bit about it in QST J
By any chance has anyone experienced self oscillation with a Centurion key up after application and removal of drive ? Mine has decided to do this on 40 meters only (into a good 50 ohm dummy load). I
FWIW _ It appears with the help of several folks on this reflector and the AMPS reflector the Centurion oscillation problem on 40 meters is resolved. It also appears the "squeal " is fixed but may re
Hi Rob - Agree with most all your comments - As I dig into the Centurion deeper , there are a lot of corners cut that I would have done differently. For instance the meters are lousy - and I am sure
Squeal was a function of time on and heating , not the band of operation. The oscillation just started at about the same time . (In fact in retrospect - I think it was oscillating when new and I did
I wanted to say one last about my Centurion issue. I want to make it clear I am VERY pleased with the help from Tentec service - In my opinion they have gone above and beyond the call of duty and far
Len - FWIW - I finally got tired of listening to my relay boing on break - tore the Orion apart and replaced the relay (TT had sent me a replacement relay) - I can no longer hear it unless I put my e
Could someone measure the open circuit voltage they see from pin 3 (PTT) to ground for me ? My front panel PTT quit working on ssb. I measured 1.002 volts hot after several hours and just turned it o
Mike - I fired up the Centurion -- The new plate meter is well damped -- With a final plate current of 600 ma it goes up to 667 ma and drops back to 600 ma - no undershoot with key up. The grid / mul
Martin - have you even taken off the back panel to get to the board with the keying relays on it ? I looked at mine and decided I would listen to the relay "boing" awhile longer - I know which one it
Bill - I just looked at the schmatic for the RS35 series -- it does not have an internal bleeder so I suspect thats why he put one external -- Hank K7HP
A few weeks ago I had a signal at S9 plus 55 db from a local dxer 800 cycles above an S2 dx station on 40 cw . I could still copy the S2 dx !!!! - I knew the local was there but the dx was readable !
Geppe - do I understand you correctly that your neighbors have TVI and you do not on the same cable system ??? Are you connected to the same system as your neighbors ? If so verrrry strange - especia
Martin -- a comment - something I would like to have is the ability to disable the audio "un-squelch" on control rotation. I don't mind pressing the control to get audio back - but I continually bump
