                           CABLE TV FUND 11-C, LTD.
                           ------------------------
                            (A Limited Partnership)

                    NOTES TO UNAUDITED FINANCIAL STATEMENTS
                    ---------------------------------------


(1)  This Form 10-Q is being filed in conformity with the SEC requirements for
unaudited financial statements and does not contain all of the necessary
footnote disclosures required for a fair presentation of the Balance Sheets and
Statements of Operations and Cash Flows in conformity with generally accepted
accounting principles. However, in the opinion of management, this data includes
all adjustments, consisting only of normal recurring accruals, necessary to
present fairly the financial position of Cable TV Fund 11-C, Ltd. (the
"Partnership") at June 30, 1997 and December 31, 1996, its Statements of
Operations for the three and six month periods ended June 30, 1997 and 1996 and
its Statements of Cash Flows for the six month periods ended June 30, 1997 and
1996. Results of operations for these periods are not necessarily indicative of
results to be expected for the full year.

     The Partnership is a Colorado limited partnership that was formed pursuant
to the public offering of limited partnership interests in the Cable TV Fund 11
Limited Partnership Program (the "Program"), which was sponsored by Jones
Intercable, Inc. (the "General Partner"), to acquire, own and operate cable
television systems in the United States.  Cable TV Fund 11-A, Ltd. ("Fund 11-
A"), Cable TV Fund 11-B, Ltd. ("Fund 11-B") and Cable TV Fund 11-D, Ltd. ("Fund
11-D") are other partnerships that were formed pursuant to the Program.  The
Partnership, Fund 11-A, Fund 11-B and Fund 11-D formed a general partnership
known as Cable TV Joint Fund 11 (the "Venture") in which the Partnership owns a
27 percent interest.  The Partnership does not directly own any cable television
systems.  The Partnership's only asset is its 27 percent ownership interest in
the Venture, and the Venture's only asset during the period covered by this
report was the cable television system serving subscribers in Manitowoc,
Wisconsin (the "Manitowoc System"), which was sold June 30, 1997.

(2)  On June 30, 1997, the Venture completed the sale of the Manitowoc System to
a wholly owned subsidiary of the General Partner for a sales price of
$16,122,333, subject to normal working capital closing adjustments. This
transaction was approved by a majority of the Partnership's limited partnership
interests in a vote conducted during the second quarter of 1997. The Venture
repaid all of its indebtedness, which totaled $21,304. In July 1997, the
Partnership received 27 percent of the net sales proceeds plus cash on hand from
operations and prior sales, totaling $5,271,500, which was distributed to its
partners. Cash generated from operations of $344,412 was distributed 99 percent
to the limited partners and 1 percent to the General Partner. Because limited
partners have already received distributions in an amount in excess of the
capital initially contributed to the Partnership by the limited partners, the
remaining proceeds (from the sale of other Wisconsin systems formerly owned by
the Venture and the net proceeds from the sale of the Manitowoc System) were
distributed 75 percent ($3,695,317) to the limited partners and 25 percent
($1,231,772) to the General Partner. In total, the limited partners, as a group,
received $4,036,284 and the General Partner received $1,235,216. As a result of
these distributions, the limited partners received approximately $146 for each
$500 limited partnership interest, or approximately $292 for each $1,000
invested in the Partnership. The limited partners of the Partnership have
received a total of approximately $1,126 for each $500 limited partnership
interest, or approximately $2,252 for each $1,000 invested in the Partnership,
taking into account the prior distribution to limited partners made in 1990. The
General Partner is in the process of formally dissolving the Partnership and the
Venture, which should occur before yearend.

FINANCIAL CONDITION
-------------------

     The Partnership owns a 27 percent interest in the Venture.  The
Partnership's investment in the Venture, accounted for under the equity method,
decreased by $2,483,268 to $69,539 at June 30, 1997 from $2,552,807 at
December 31, 1996.  This decrease represents the Partnership's proportionate
share of income generated by the Venture during the first six months of 1997
reduced by distributions received from the Venture.

     On June 30, 1997, the Venture completed the sale of the Manitowoc System to
a wholly owned subsidiary of the General Partner for a sales price of
$16,122,333, subject to normal working capital closing adjustments.  This
transaction was approved by a majority of the Partnership's limited partnership
interests in a vote conducted during the second quarter of 1997.  The Venture
repaid all of its indebtedness, which totaled $21,304.  In July 1997, the
Partnership received 27 percent of the net sales proceeds plus cash on hand from
operations and prior sales, totaling $5,271,500, which was distributed to its
partners.  Cash generated from operations of $344,412 was distributed 99 percent
to the limited partners and 1 percent to the General Partner.  Because limited
partners have already received distributions in an amount in excess of the
capital initially contributed to the Partnership by the limited partners, the
remaining proceeds (from the sale of other Wisconsin systems formerly owned by
the Venture and the net proceeds from the sale of the Manitowoc System) were
distributed 75 percent ($3,695,317) to the limited partners and 25 percent
($1,231,772) to the General Partner.  In total, the limited partners, as a
group, received $4,036,284 and the General Partner received $1,235,216.  As a
result of these distributions, the limited partners received approximately $146
