What a horrid, miserable radio. I owned one brand new in 1971 as ordered
from Allied radio shortly before their demise.

The A-model has a bit more IF bandwidth due to one IF filter stage being
eliminated and replaced with a jumper wire on the circuit board. This spoke
volumes of the crappy design: imagine, the "improved" A-version actually
has less parts due to the fact that an entire stage in the IF was removed!

My 2515 model suffered from excessive drift, instability, bandswitch
glitching, microphonics, poor sensitivity above 20Megs, scratchy
pots.....and that was when the darned thing was NEW!

The A-model may be more desirable due to its selectivity being wider than
that of a razor blade. AM on my 2515 was absolutely miserable and devoid of
any detected audio above 1,500cps. It always sounded like you were
listening to a radio with a paper bag over your head.

No wonder Allied fizzled. This was the Company's last, dying attempt at
marketing a house-brand "communications" receiver. I can see why anyone at
TRIO would never admit to desingning the fool thing.

Anyone know the difference between the 2515 and the 2515A?

I wonder who built this rcvr? Trio maybe?

Thanks
