NEED MORE RELIABLE INTERSTAGE AND OUTPUT TRANSFORMERS
The problem of constructing reliable interstage and output transformers
for Rodina receivers is still unsolved by the radio plants of the Ministry of
the Communications Equipment Industry. For the last few years, reports have
been coming in from radio repair shops and radio amateurs that the transformer
windings of Rodina radios broke quickly and that, because of design peculiari-
ties, it was impossible to rewind these transformers. Thus, because of the
poor quality of these parts, many Rodina and Rodina-1+7 receivers are not oper-
ating.
Here, for example, is what the radio amateur A. Prokopenko has written
from Berestechko, Volyn' Oblast:
"In Volyn?, and probably in other regions of the USSR, it would be hard
to find a village which does not have some radios. Village clubs, village
reading rooms, and radio amateurs have them. Most of them are Rodina battery
receivers. But at least half of these receivers are not in operation because
of breakdowns in the interstage and output tranesr uu-e .
"It is impossible to repair these transformers because they are wound
without cores and impregnated with a resin compound. As we all know, there
are no spare transformers on sale, and consequently damaged transformers can-
not be replaced.
"It seems to me that it should be possible to construct more durable
transformers or, at least, to place the windings on a core and not impregnate
them with resin, so that a radio amateur could rewind them."
Similar complaints were received from I. Shapiro, radio technician of
the repair shop of the Pskov Wired Radio Network; from the radio amateur, P.
Semlyak, Pavlovka Village, Stalin Oblast; and others. These are not just oc-
casional complaints.. They have been coming in for several years. Many of
them have been published in this journal.

COHFloENTIA1.
The solution to this problem is obvious. The plants must place a suffi-
cient number of these transformers on sale. The most
the consumer would be to make spare parts
tothey need not be scattered
(Mail Ore rhO five, Ministry of Trade) so that
This measure would be the first step toward eliminating the present situa-
tion. It can and must be done at once. But in the future, transformers which
cannot be repaired must not be used in mass-produced receivers for rural areas.
