After owning an Omni VI for a few months I had a hankering to try the Paragon II transceiver. I was lucky enough to find one in working condition a few months later. I've been able to add a full filt
The left lamp has been driving me nuts :) It would flicker, go dim, or go out. Opened the case several times and tried a new lamp, cleaning the lamp socket contacts, checking the PC board cable and c
I'd like to modify my Paragon II to permit setting power output to under 25 watts. I have the directions for the change for the Paragon 585 model, but they don't correlate to the schematic for the 58
I guess there aren't too many Paragon II owners out there these days... Anyway , my best *guess *is that the part referenced in the Ten Tec wiki for the QRP mod should be changed from R44 100K to R39
I may be missing something, but I don't see how the 455kHz mechanical filters can do much to improve the 2nd mixer in band IMD performance for the Omni VII. The limiting factor is the 70 MHz 1st IF f
Gary, I am not sure what you are seeing in that presentation, but the first few slides clearly show that the roofing filter selectivity is what determines the receiver's close in dynamic range. A 20
The lithium backup battery in the Dallas RTC chip has failed. You have two Dallas chips in the 586. One is for the non-volatile RAM, the other is for the time function. Look on page 4-18 in your manu
Your Dallas RTC chip has an internal lithium battery that failed. You will need to order a new DS-1287 Dallas chip from Ten Tec (20 bucks) and replace the device. Unfortunately, it is a 24 pin part t
I'm not sure if you do a lot of split operation when chasing DX, but the early Omni VI A and B VFOs cannot be independently locked. I find myself spotting the QSX, and then accidentally moving the DX
My Paragon II had the original Dallas chips, despite the rig's age the internal 3 volt lithium cells were still viable in both of the Dallas devices. To be proactive, I ordered two replacements from
Hello to the group I just picked up a used Paragon II and have several questions... First, where is the backup battery located? I've read that the Paragon uses a long life lithium cell, but I can't l
Thanks Mike... that confirms my suspicions. I'd also guess the Dallas time chip has an internal battery for the clock. Those Dallas chips seem to run forever. I'd wonder if anyone has opened one up t
Hello to the group!! I still need a Ten Tec 250 Hz CW filter for the 6.3 MHz IF in my Paragon II. I've located a project power supply, and a 500 Hz filter.. If you have a spare for a reasonable price
This is an early Omni VI. I cannot lock A or B VFO individual. If I lock one, they both are locked. I have tried various combinations of locking A first, then going to spit, going to split first, and
I recently came across a 586 Paragon II and in a moment of weakness I bought it to keep my Omni VI company (I wanted a general coverage rig) The radio already has two SSB filters, but I'd also like t
Power Supply has been located, thank you Al! I could still use two CW filters, to clarify these would be a #285 500Hz and a #282 250 Hz 6.3MHz IF filter. Had several nice offers for 9 MHz filters, I
Hello to the group I'm in the processing of rescuing a much abused TenTec 280 power supply. There is no amp meter on the front, but it has the speaker, so I assume it may be a model 255 despite what
