Hi folks,What is a fair price for  Paragon 586 with 285 filter and a 961 power supply/ speaker.I also have the matching 253 automatic tuner. I have the original manual for the rig along with the orig

I'm nearly finished with the restoration of a Triton IV (544 digital). I hear a pulsing frequency marker at 14.0 MHz but my 544 manual makes no mention of it. It's definitely not a 25 kHz or 100 kHz

H Paul, I thought that sounded familiar so I turned on my 544. No antenna connected I have a pulsed signal ( 4 to 5 beats per second ). With the zero beat knob pulled out it zeroes out at 14.0004; kn

Unplug the the frequency display and see if the signal goes away. The signal is coming from that unit. Verify it first and the decouple the vcc going into the display unit Mike. Wb8vge Sent from my i

When you first hear it, youd bet money that the calibrator is running. However, there isnt one in the digital Triton 4. Decoupling the power supply will reduce the signal level to a point you wont no

Mike, Interesting. If the 544 schematic is correct, the Display Board has no common +Vcc. +Vcc is supplied individually to each 7-segment LED module via Q14-Q19 (PNP) on the Logic Board. +Vcc on the

Ive never done a shotgun approach when it comes to replacing electrolytic capacitors, but in the case of this particular display unit, that was alway the first thing I did. Then, and its been years a

Mike, That's what confused me. I knew the 544 had no switched calibrator function but it sounds just like the calibrator in the analog Triton IV. Paul, W9AC that most likely was the calibrator, they

It is not at all unusual for electrolytic capacitors to decrease in value as they age.  Thus an original 10mfd, after a few, years may effectively be a 1mfd capacitor.  Although I don't care for the

After reading these posts, checked my 544. No such pulses anywhere. If they only appeared at 14.0, I wouldnt care. I never operate on band edges. -de K4CWQ Sent from my iPhone _______________________
