I can hear 26.755, 26.745 and 26.695 locally in Richmond VA using a handheld.
On the W3HFU SDR - specifically the one with the 900 foot sky loop antenna
26.950 MHz FM - Weak paging signals
26.900 MHz FM - Pager signals, POCSAG - barely above the noise
26.855 MHz FM - Pager signal bursts, likely offset freq for 26.85 MHz
26.850 MHz FM - Paging bursts, severe QRM from CB traffic on 26.845 MHz and 26.855 MHz
26.755 MHz FM - POCSAG bursts, sporadic
26.750 MHz FM - POCSAG signals, other data bursts (same data signals noted on 26.65 MHz)
26.745 MHz FM - Constant paging signals, first tuned in around 1600 UTC. Signal strength increased around 1630 UTC
26.695 MHz FM - Constant pager signals, POCSAG
26.650 MHz FM - Paging bursts, narrow band (4-5 kHz wide BW), similar to some of the signals on 26.750 MHz
26.600 MHz FM - Paging signals noted around 1650 UTC and 1655 UTC
26.500 MHz FM - Constant FM "idle" signal, reminds me of 26.200 MHz and 27.450 MHz (both European paging systems)
26.500 MHz FM - POCSAG paging signals
26.450 MHz FM - POCSAG - narrowband signals, weak to fair at 1650 UTC - 1655 UTC
26.250 MHz FM - POCSAG paging signals, mostly narrowband, sporadic, wide band (12 kHz BW) noted at 1658 UTC
26.200 MHz FM - Constant FM "idle" signal, being sent even when paging transmissions are sent - POCSAG (12 to 14 kHz bandwidth!)

1705 UTC
Strong signal in to NEPA

26.695 MHz and 26.745 MHz are the strongest at my local receive location as well.
They're both "offset" frequencies, 26.695 MHz being the offset for 26.700 MHz (26.700 MHz and 26.705 MHz are also used for paging), 26.745 MHz being the offset for 26.750 MHz.
