While it is certainly the case that RS10/11 and RS12/13 were 'parasite' 
packages flown attached to large spacecraft, other RS birds were not.

RS3-RS8 launched together on a small KOSMOS launcher (alongside RS1 & 2) 
were much smaller birds and although information is patchy, were probably 
based on the small STRELA satellite bus used by the Russian military for 
store-dump battlefield communications. They did not have the benefit of 
'stealing' power for a larger craft and were autonomous amateur radio birds 
with fairly small solar generators.  These small craft although in LEO (I 
believe 1000Kms) put out cracking signals and were very popular birds.
Much of course depends on whether you use a piece of wet string or a proper 
antenna on the ground:-)  Signal strength is a subjective issue.
