[Elecraft] Poor RX on SSB

[Richard Hemingway]

I have just finished my K3 kit and it seems to be working just fine. 
However, I have been trying to tune into FD on SSB and find poor 
reception.  I should explain that I live in a retirement community 
and only have a Isotron 20M antenna sitting on the top of a bookcase 
by a window on the second floor. However, that said I should further 
explain tht I usually can receive SSB fairly well.  I am receiving CW 
great and PSK (which I usually use) pretty well.  The SSB signals 
seem to be down in  the mud,  while the CW signals are very strong.

I am new to this reflector (and to the K3) and this may be a dumb 
question.  Any help on this or advice would be appreciated.

Thanks,
