Kenwood TR 7800 User manual

A Note From
Dave Miller (AA4DF) and Jill Bryant
at
http://www.aa4df.com
First, please know that we not only provide free PDFs like this one, we also supply
PDF documents for profit. Please know that there is never an extraneous letter (like
this one) added to PDFs we sell.
This TR-7800/7850 Service document is provided to you through the generosity of
Steve, K7LZJ.
This PDF is made from a photostat copy of an original. The 600 dpi scans made
from the copy are available on CD from our web site, as they are too large to
transmit over FTP. We don’t recommend them for higher quality, though, since
readability doesn’t perceptibly improve with them since the original source was a
copy.
You will soon note that “marketing” and “leeching” vendors will soon be selling this
scan on eBay. “The Leech” in Houston will say nothing about quality, and “The
Marketer” in Minnesota will make up specifications to pretend he scanned it
himself, as he does with so many HP factory downloads. Please support original
PDF producers; “leeches” and “marketers” who obtain and sell the work of others
or sell free internet download material to naïve eBay buyers for high prices are
directly responsible for the scarcity of new material in the scanned manuals trade.
Also, PLEASE don’t upload this to K4XL’s BAMA! BAMA has plagiarized most of
our Tektronix material, and if you investigate you’ll see that they have a great deal
more test equipment manual inventory than useful ham radio inventory (after all,
test equipment docs are “where the money is”) even though they masquerade as a
ham radio site, and that coupled with the presence of the words “if you bought this
from anyone other than BAMA…” locked into the material pretty well tells you
what their intentions are. Wildly waving the “FREE! FREE! FREE!” banner they
are tricking decent people into plagiarizing working vendors, with the ultimate
objective being for BAMA to profit from the labor of others at no cost to themselves.
Otherwise, pass it around all you wish. Thanks for taking the time to read this.

PLL Unit (X50-1650-10)
Fig. 2 shows a baslc block diagram of the PLL circurt. The
VCO s~gnalfrom
Q1 is buffered by 02 and amplified by 09.
It is then mixed wrth the heterodyne srgnal by Q13 to
produce a
5.4 - 10.49 MHz s~gnal.
This signal isfrltered and then amplif~edby Q12-10, and then
frequency dlvided by
01 6 according to the binary data (1 0
MHz. 1 MHz, 100 kHz and 10 kHz order) from the control
unit to obtain a
10 kHz step s~gnal.
The 10.24 MHz signal from the RX unit is frequency divided
