Regarding QRP operation, Nigel G8IFF writes:
"Setting a TR7 for QRP is relatively easy. Turn the ALC pot down (I
think it's on the driver board). Having had blown up PA transistors on
mine, I've set mine for 100W out on all bands and use a speech
Alternatively, the driver board probably runs a watt or so without the
PA module. (Then, whoever wanted to know, can send me his PA module to
use with my FT-817!)"

Regarding Modification No. 8 (LF Coverage) Marcus PA0MLC writes:
"In order to improve the sensitivity of the LF frequencies one may
remove the 20 dB attenuator which is inserted in the RF path when
using the LF antenna input. However,
care must be taken as RF feedback during TX via this path is now
(without the 20 dB att) very much likely.
Nevertheless, the improvement of the sensitivity is worthwhile,
in my opinion."
