If you adjust those inductors in the band select oscillators be very careful. It is easy to wear out the threads in the slugs and/or the coil forms the slugs screw in. It is also easy break the adjus

Hi Carlos, Thanks for the interesting information. I'm curious about the 160 and 80 meter filters. If their bandpasses were not at the right frequencies, where were they before you changed the capaci

There is some interaction between the BFO adjustments. The specified order of adjustmenting them is intended to reduce the number of iterations of adjustments necessary to finally get them all right.

Since I don't have a schematic for that radio to look at I'm not sure where T3 is. Input to final transistors or output? Even so, direct comparison on a wattmeter may be misleading. The impedance is

Hi Snowy, I guess I don't know exactly what your pig tail setup is. When you connect to the collectors of the drivers do you mean you have your leads paralleled across the primary windings of T3 load

What kind of Fluke meter are you using? Are you expecting to measure RF voltage with it? If a regular Fluke DMM you can reasonably expect to measure DC collector voltages and DC base bias voltages, b

Check all the things that are common to both the transmit and receive function. If front panel indications all seem normal, VFO readout etc. you can probably rule out power supply, or power distribut

Oops, send before finishing. Can your general coverage receiver hear anything from the Omni VI when transmitting, even it there is not enough power to register on your wattmeter/SWR meter? Can your g

On the other hand using FSK instead of AFSK eliminates the possibility of audio level problems. And there is no concern about opposite sideband rejection or carrier suppression on your transmit signa
