Good! Now we know that the oscillator is working and is working at the proper tuning range. This will assure that the stations received will be on there proper places on the dial.
Part 2
With your antenna connected tune in a local station near 600kc then adjust L2 for loudest signal from the spkr. Find a local station near 1300kc and C1 for loudest from the spkr.
Just for grins tune your generator to 455kc. Connect the output to the antenna post of your Hammerlund and listen for it's signal @ 910kc (that would be the generator's 2nd harmonic 455x2=910) to see if your generator is on frequency @455kc. If your not hearing a signal at 910kc then retune the generator till you do then re adjust the IF transformers in your RCA noting that all of the adjusts (4) do make some difference when adjusted. If not there is a problem with the IF transformer.
Just to be clear your set doesn't have a built in loop ant it does require an external ant to hear much of anything. With that being said it should be able to pick stations with 10-15' of wire hooked up to it. I would think that WSB should knock your sock off as I can get it up here near Phila.
Sorry we have to have done this sort of basacwards but I want to be sure there wasn't a problem with the osc. It's doing it's thing! This set going to make you a pro at fixin'
