Even when all systems are properly connected to the same ground buss, there can be slight potential differences caused by magnetic fields from transformers, and in RF transmitting systems by electrom

Hi all, I finally found the time to work on my Titan 425 amplifier, trying to reduce the noise radiated (mechanical noise, radiated acoustically) by the vacuum relay. I removed the relay board and fo

My Titan 425 sits on some packaging foam sheets. The foam is between the front supporting bail and the desk top, and also between the rear fee and the desk top. That makes a huge reduction in the vib

Sounds like a good method to me. I am curious about the LDG tuner. I presume the LDG has a built in frequency counter to address tuning memories for each frequency, or does it use a data connection f

I understand Ten Tec had a 2 page alignment sheet for the Omni6 Plus. Does I've never seen anything like that in any of the Ten-Tec manuals and other papers I have for my Omni VI. I sure would like a

Hi John, The information needed to perform a complete alignment of an Omni VI may in fact be contained in the manual. However it is not all in one place and listed in the most efficient order. Each o

Hi Ron, If your logic is impeccable, yet built on incorrect premises, you can make false conclusions. For example, in most radios that have a digitally controlled VFO, with memories, all of the oscil

I also built an attenuator from 2 watt carbon composition resistors. My application was a Kenwood TS-440 driving a SGC SG-500 amplifier. The ALC circuitry in the TS-440 made the keying envelope funny

Putting it on the bench and checking it out, without making any (internal) adjustments is a good idea. A log of power output and power supply current draw on every band, would be good data for compar

I thought there was something wrong with my listing of those last three filters. I'll update the list to show them as filters for the Omni VII. Thanks for the correction. DE N6KB ___________________

Hi Chuck, Most ham amplifiers have dual primaries on their single power transformer, which can be connected in series for 240 VAC operation, or in parallel for 120 VAC. Since they can be wired for ei
