[ARC5] 10 meter BC-454 - another bit of news.

[john rose]

It's not that unusual. I remember that at least one of the many rigs that passed through my shack had high side injection except the highest band which had low side injection. On AM it means nothing. The oscillator was a bit more stable that way and easier to get good drive at 29 Mc vs 31 Mc.
Don't forget that at the dawn of the SSB era hams built 9 Mc IF filter strips to get one sideband and beat that against a 5 Mc VFO. 9 + 5 = 14, 20  Mtrs and 9 -5 = 4 or the top of 80 and the sidebands get inverted. Big deal. That's why the ham convention on 80 and 40 is the opposite of every other user in the ether. What keeps the fiddler on the roof? Tradition!
