See the following for my description of Omni VI filtering. I posted it here and I guess W8KC (SK) thought it was good enough to put on his web site. http://home.comcast.net/~w8kc/n6kb.htm DE N6KB __

When an Omni VI has the VCXO adjustments, C24 and R18, on the 6.3 MHz IF / PASS BAND TUNING BOARD adjusted properly, the PBT adjustment range is 4 kHz total, or +/- 2 kHz. In CW, LSB or FSK modes (a

Think about it mathematically. With an L network you have only two variables, the inductor and the capacitor. The goal is to transform the impedance of the load to 50 ohms resistive. The load can be

"What is the serial number of the VI + ? Does it have TCXO and SMT?" I believe that any Omni VI + has boards with SMT devices. And any Omni VI version three has SMT devices on the 9 MHz Filter Board,

Hi Ken, The Paragon receives CW in USB, unlike the Omni VI which receives LSB CW. It appears to me that the BFO frequency used for USB and CW receive is 9.000 MHz. If I'm right about that, then you

If it is a Ten-Tec model 238 or 235, and probably also 229, there are only two configurations available. Those two configurations both have the L in series. The shunt C can be switched to either the

Yes the numbers do speak. Very few people have 222 MHz capability. I think for a 222 MHz radio to sell many units, it has to be a mobile, with a bit a power capability. Alinco makes one and I guess f

Unless the stock bulbs are 6.3 volt lamps, in which case you will want a lower voltage, perhaps 7 volt rating, to make it last a lot longer than a 6.3 volt lamp. DE N6KB ____________________________

Hi Jim, Since Marinus' first post referred to a Ten-Tec 228 tuner, you are correct about the 12 to 14 volt supply. Marinus also mentioned the bulbs in his Omni 546-C, and asked whether they are 6 vol

One can easily be comfortable with computer programming and still prefer not to be dependent on a computer to operate their radio, so I would say the first part of your hypothesis is not necessarily
