I was not a fan of the 448, especially if someone had clobbered the obscure PLL chip trying to add channels. The 449 is just a better design and better built, both IMHO.

Naturally, alignment is the first diagnostic step for low transmit power after 45 years have passed. Watching to see that none of the tuning slugs show a peak with the top of the slug DEAD EVEN with the rim of the hole is the next thing to watch for during alignment. Well over half the decades-old radios we see with this symptom will respond to alignment, or prove to have one or more tunable coils with the "dead even" fault.
