                           CABLE TV FUND 11-D, 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-D, Ltd. (the
"Partnership") at September 30, 1996 and December 31, 1995, its Statements of
Operations for the three and nine month periods ended September 30, 1996 and
1995 and its Statements of Cash Flows for the nine month periods ended September
30, 1996 and 1995. 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-C, Ltd. ("Fund
11-C") are the other partnerships that were formed pursuant to the Program.  The
Partnership, Fund 11-A, Fund 11-B and Fund 11-C formed a general partnership
known as Cable TV Joint Fund 11 (the "Venture") in which the Partnership owns a
47 percent interest.  The Partnership does not directly own any cable television
systems.  The Partnership's only asset is its 47 percent ownership interest in
the Venture, and the Venture's only asset is the cable television system serving
subscribers in Manitowoc, Wisconsin (the "Manitowoc System").

(2)  The General Partner manages the Partnership and the Venture and receives a
fee for its services equal to 5 percent of the gross revenues of the Venture,
excluding revenues from the sale of cable television systems or franchises.
Management fees paid by the Venture and attributable to the Partnership for the
three and nine month periods ended September 30, 1996 (reflecting the
Partnership's 47 percent interest in the Venture) were $21,871 and $64,955,
respectively, compared to $21,796 and $62,927, respectively, for the similar
1995 periods.

     The Venture reimburses the General Partner for certain allocated
overhead and administrative expenses.  These expenses represent the salaries and
related benefits paid for corporate personnel, rent, data processing services
and other corporate facilities costs.  Such personnel provide engineering,
marketing, administrative, accounting, legal and investor relations services to
the Venture.  Allocations of personnel costs are primarily based upon actual
time spent by employees of the General Partner with respect to each partnership
managed.  Remaining expenses are allocated based on the pro rata relationship of
the Venture's revenues to the total revenues of all systems owned or managed by
the General Partner and certain of its subsidiaries.  Systems owned by the
General Partner and all other systems owned by partnerships for which Jones
Intercable, Inc. is the general partner are also allocated a proportionate share
of these expenses.  The General Partner believes that the methodology used in
allocating overhead and administrative expenses is reasonable.  Reimbursements
to the General Partner paid by the Venture and attributable to the Partnership
for allocated overhead and administrative expenses for the three and nine month
periods ending September 30, 1996 (reflecting the Partnership's 47 percent
interest in the Venture) were $28,402 and $90,962, respectively, compared to
$32,276 and $96,239, respectively, for the similar 1995 periods.

(3)  The Venture has entered into an asset purchase agreement to sell the
Manitowoc System to the General Partner. Because the City of Manitowoc had not
consented to the transfer of the franchise by the asset purchase agreement's
original expiration date of September 30, 1996, the Venture and the General
Partner amended the asset purchase agreement to extend the period in which to
close the sale of the Manitowoc System to June 30, 1997. The amendment also
provides for the purchase price to be the greater of (i) $15,735,667, which was
the average of three independent appraisals of the Manitowoc System obtained by
the Venture in 1995, and (ii) the average of three updated appraisals of the
Manitowoc System. The average of the three appraisals obtained by the Venture in
November 1996 was $16,122,333. Accordingly, under the terms of the asset
purchase agreement, as amended, the purchase price of the Manitowoc System will
be $16,122,333.

                                       5
<PAGE>
 
     The closing of the sale of the Manitowoc System is subject to the approval
of the City of Manitowoc and the approval of the limited partners of each of the
partnerships that comprise the Venture.  There can be no assurance that any
such approvals will be obtained.  In October 1996, the Venture and the General
Partner filed an updated request for the approval of the City of Manitowoc to
the transfer of the franchise.  The General Partner, on behalf of the
partnerships that comprise the Venture, is in the process of preparing proxy
solicitation materials to seek the approval of the limited partners of the four
constituent partnerships of the Venture.

     The original term of the franchise with the City of Manitowoc expired in
1995.  The franchise has been extended by the Venture and the City of Manitowoc
periodically since that time.  The current extension ends on December 31, 1996.
If the franchise is not renewed by such date, the General Partner will seek an
additional extension from the City in order to complete the renewal of the
franchise and to obtain the City's consent to the transfer of the franchise to
the General Partner.

(4)  Financial information regarding the Venture is presented below.

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

     Cable TV Fund 11-D, Ltd. (the "Partnership") owns a 47 percent interest in
Cable TV Joint Fund 11 (the "Venture"). The Venture owns and operates the cable
television system serving the areas in and around the City of Manitowoc,
Wisconsin (the "Manitowoc System"). The Partnership's investment in this
Venture, accounted for under the equity method, has increased by $206,588 to
$2,918,652 at September 30, 1996 from $2,712,064 at December 31, 1995. This
increase represents the Partnership's proportionate share of income generated by
the Venture during the first nine months of 1996.

     The Venture has entered into an asset purchase agreement to sell the
Manitowoc System to the General Partner. Because the City of Manitowoc had not
consented to the transfer of the franchise by the asset purchase agreement's
original expiration date of September 30, 1996, the Venture and the General
Partner amended the asset purchase agreement to extend the period in which to
close the sale of the Manitowoc System to June 30, 1997. The amendment also
provides for the purchase price to be the greater of (i) $15,735,667, which was
the average of three independent appraisals of the Manitowoc System obtained by
the Venture in 1995, and (ii) the average of three updated appraisals of the
Manitowoc System. The average of the three appraisals obtained by the Venture in
November 1996 was $16,122,333. Accordingly, under the terms of the asset
purchase agreement, as amended, the purchase price of the Manitowoc System will
be $16,122,333.

     The closing of the sale of the Manitowoc System is subject to the approval
of the City of Manitowoc and the approval of the limited partners of each of the
partnerships that comprise the Venture. There can be no assurance that any such
approvals will be obtained. In October 1996, the Venture and the General Partner
filed an updated request for the approval of the City of Manitowoc to the
transfer of the franchise. The General Partner, on behalf of the partnerships
that comprise the Venture, is in the process of preparing proxy solicitation
materials to seek the approval of the limited partners of the four constituent
partnerships of the Venture.

     The original term of the franchise with the City of Manitowoc expired in
1995. The franchise has been extended by the Venture and the City of Manitowoc
periodically since that time. The current extension ends on December 31, 1996.
If the franchise is not renewed by such date, the General Partner will seek an
additional extension from the City in order to complete the renewal of the
franchise and to obtain the City's consent to the transfer of the franchise to
the General Partner.

     During the first nine months of 1996, the Venture expended approximately
$251,000 for capital additions in the Manitowoc System.  These capital additions
were for various enhancements to maintain the value of the system until it is
sold and were funded from cash generated from operations.

     The Venture had no bank debt outstanding at September 30, 1996.

     The Venture has sufficient liquidity and capital resources, including cash
on hand and its ability to generate cash from operations, to meet its
anticipated needs.

RESULTS OF OPERATIONS
---------------------

     All of the Partnership's operations are generated through its 47 percent
interest in the Venture.  Revenues of the Venture increased $3,162, or less than
1 percent, to $932,834 for the three months ended September 30, 1996 compared to
$929,672 for the comparable 1995 period.  Revenues of the Venture increased
$86,495, or approximately 3 percent, to $2,770,517 for the nine months ended
September 30, 1996 compared to $2,684,022 for the comparable 1995 period.  An

                                       8

increase in the number of basic subscribers primarily accounted for the increase
in revenues for the three and nine month periods ended September 30, 1996.  The
number of basic subscribers increased by 422 subscribers, or approximately 4
percent, to 11,524 at September 30, 1996 from 11,102 at September 30, 1995.  No
other individual factor contributed significantly to the increase in revenues.

     Operating expenses consist primarily of costs associated with the
administration of the Manitowoc System.  The principal cost components are
salaries paid to system personnel, programming expenses, professional fees,
subscriber billing costs, rent for leased facilities, cable system maintenance
expenses and consumer marketing expenses.

     Operating expenses in the Manitowoc System decreased $12,203, or
approximately 2 percent, to $548,465 for the three months ended September 30,
1996 compared to $560,668 for the comparable 1995 period.  Operating expenses in
the Manitowoc System decreased $72,490, or approximately 4 percent, to
$1,662,876 for the nine months ended September 30, 1996 compared to $1,735,366
for the comparable 1995 period.  Operating expenses represented approximately 59
percent and 60 percent, respectively, of revenues for the three and nine month
periods of 1996 and approximately 60 percent and 65 percent, respectively, for
the comparable 1995 periods.  The decreases in operating expenses for the three
and nine month periods were due to a significant decrease in property taxes, as
a result of a change in the method used to assess the assets of the Manitowoc
System.  No other individual factor significantly affected the decreases in
operating expenses.

     Management fees and allocated overhead from the General Partner decreased
$8,104, or approximately 7 percent, to $107,213 for the three months ended
September 30, 1996 compared to $115,317 for the comparable 1995 period.
Management fees and allocated overhead from the General Partner decreased
$6,929, or approximately 2 percent, to $332,515 for the nine months ended
September 30, 1996 compared to $339,444 for the comparable 1995 period.  The
decreases for the three and nine month periods were due to decreases in
allocated overhead from the General Partner.

     Depreciation and amortization expense decreased $31,639, or approximately
23 percent, to $107,926 for the three months ended September 30, 1996 compared
to $139,565 for the comparable 1995 period.  Depreciation and amortization
expense decreased $94,710, or approximately 23 percent, to $323,984 for the nine
months ended September 30, 1996 compared to $418,694 for the comparable 1995
period.  The decreases for the three and nine month periods were due to the
maturation of the intangible asset base.

     Operating income increased $55,108, or approximately 48 percent, to
$169,230 for the three months ended September 30, 1996 compared to $114,122 for
the comparable 1995 period.  Operating income increased $260,624 to $451,142 for
the nine months ended September 30, 1996 compared to $190,518 for the comparable
1995 period.  The increases for the three and nine month periods were due to the
increases in revenues and the decreases in operating expenses, depreciation and
amortization expense and management fees and allocated overhead from the General
Partner.

     The cable television industry generally measures the financial performance
of a cable television system in terms of cash flow or operating income before
depreciation and amortization.  The value of a cable television system is often
determined using multiples of cash flow.  This measure is not intended to be a
substitute or improvement upon the items disclosed on the financial statements,
rather it is included because it is an industry standard.  Operating income
before depreciation and amortization increased $23,469, or approximately 9
percent, to $277,156 for the three months ended September 30, 1996 compared to
$253,687 for the comparable 1995 period.  Operating income before depreciation
and amortization increased $165,914, or approximately 27 percent, to $775,126
for the nine months ended September 30, 1996 compared to $609,212 for the
comparable 1995 period.  The increases for the three and nine month periods were
due to the increases in revenues and the decreases in operating expenses and
management fees and allocated overhead from the General Partner.

     Interest income increased $7,743, or approximately 15 percent, to $59,756
for the three months ended September 30, 1996 compared to $52,013 for the
comparable 1995 period.  Interest income increased $49,380, or approximately 39
percent, to $175,214 for the nine month period ended September 30, 1996 compared
to $125,834 for the comparable 1995 period.  The increases were due to higher
cash balances and higher interest rates on interest-bearing accounts in 1996.

     Interest expense increased $135, or approximately 26 percent, to $646 for
the three months ended September 30, 1996 compared to $511 for the comparable
1995 period.  Interest expense decreased $1,296, or approximately 14 percent, to
$7,916 for the nine months ended September 30, 1996 compared to $9,212 for the
comparable 1995 period.  The decrease for the nine month period was due to lower
outstanding balances on interest bearing obligations.

     Other expense totaled $177,859 for the nine month period ended September
30, 1996 compared to other income of $1,024 in 1995.  This change was due
primarily to additional expenses incurred in 1996 from a sales and use tax
audit.

     Net income of the Venture increased $60,462, or approximately 36 percent,
to $226,295 for the three months ended September 30, 1996 compared to $165,833
for the comparable 1995 period.  Net income of the Venture increased $132,417,
or approximately 43 percent, to $440,581 for the nine months ended September 30,
1996 compared to $308,164 for the comparable 1995 period.  The increases were
due primarily to the increases in operating income and the increases in interest
income.
