Exhibit 99.1

                  ADDvantage Technologies Group, Inc.
                  Reports Third Quarter 2003 Increases

     Broken Arrow, Oklahoma, August 13, 2003--ADDvantage Technologies Group,
Inc. (OTCBB: ADDM) today announced its financial results for the third quarter
ended June 30, 2003.  Revenues for the third quarter fiscal 2003 rose 20.8% to
$8.2 million, as compared to $6.8 million for the third quarter of fiscal 2002.
This significant increase was primarily due to the positive results related to
marketing our products to the large cable multiple system operators ("MSO's")
as well as the meaningful distributor relationships created within the last two
years with Scientific Atlanta, Motorola and various other manufacturers.  Net
income applicable to Common Stock for the current quarter increased 67.8% to
$914,000, or $.09 per share, as compared to $545,000, or $.05 per share, in the
prior year.
     "We are pleased with our strong results, despite the weak economic
conditions that have led to a reduction in capital spending by the MSO's," said
Ken Chymiak, President of ADDvantage Technologies Group.  "Although our results
are up compared to last year, revenues decreased slightly from the previous
quarter due largely to a tornado that damaged our facilities in Deshler,
Nebraska.  While the Company maintains adequate business interruption
insurance, our other subsidiary locations were able to mitigate the impact of
the damage by filling orders as the Deshler team worked to minimize our
downtime."

ADDVANTAGE TECHNOLOGIES GROUP, INC. and its subsidiaries, TULSAT, Lee
Enterprise, NCS Industries, Comtech Services, TULSAT-Texas, and TULSAT-Atlanta
comprise an organization involved in the sale of new, surplus, re-manufacture,
repair and sale of previously owned cable television ("CATV") equipment and the
