Got the 7694 and rca preamp. Had some work/personal related things push back to next week, so I was able to test out the preamp. I haven't done anything with the 7694 yet (I will tonight), but the amp works great with the C2V UHF part, did nothing for VHF. Here are some examples:
Antenna (C2V) pointed to Philly with preamp (FM trap on)
----------------------------------------------------------------
KYW 26 (3.1) CBS - Signal strength from 64 to 100 (Max) - TV calls it MAX
WCAU 34 (10.1) NBC - Signal strength from 78 to 100 (Max)
WPSG 32 (57.1) CW - Signal strength from 66-68 to 100 (Max)
WPPX 31 (61.1) ION - Signal strength from 56 to 82-84
Scanned for channels and nothing else was picked up.
Antenna (C2V) pointed to Baltimore with preamp (FM trap on)
---------------------------------------------------------------------
WMAR 38 (2.1) ABC - Signal strength from 58-60 to 100 (Max)
WNUV 40 (54.1) CW - Signal strength from 44 to 92
WBFF 46 (45.1) Fox - Signal strength from 0 to 78-80 and coming in great
Scanned for channels and it picked up:
WNJS-DT 22 (23.1) PBS - Picture wasn't good until I pointed to about 64 Magnetic
Overall, I am impressed with the RCA preamp.
I had to give back the C2V today, but I will let you know tommorow what happens with the 7694 tomorrow.
