Re: No TX or RX
开云体育Hi there are a number of simple alignment steps, where the test point are peaked even with out much test equipment you can do around 80% ? Q1024 is a VCO locked to X1001 the component drifts over the years. ? I have known hams that when doing an alignment, accidently, move the wrong coil so make sure you find T1009 as it has many neighbours. There are manuals on this forum you can down load ? 73 ?

Thanks Andrew!? I will give the voltage check a try. Sounds easy enough.?? ? I don't know about an alignment though. I have a user manual and schematics that I downloaded but I don't have anything like an advanced or service manual so no alignment instructions.? I have a recently calibrated HP signal generator, an Agilent spectrum analyzer and a couple of scopes that do well enough for HF band work (one's a 25MHz and the other is a 50) but doing an alignment on one of these vs an old National or Hallicrafters seems a bit daunting without proper instruction. ? But I will try what you've suggested. I really want to help the guy out. He's always doing stuff for others and volunteers in the community all the time. It would be nice to give back now and then. |
