Debt Disclosure [Text Block]	Note 8 – Notes Payable and Line of Credit Loan Agreement On March 10, 2020, the Company entered into a loan agreement with its primary financial lender for $3.5 million, bearing interest at 6% per annum. The loan is payable in seven semi-annual installments of principal and interest with the first payment occurring June 30, 2020, and the final payment due June 30, 2023. Payment of the loan may be accelerated in the event of a default. The principal and interest payments correlate to the payment schedule for the promissory note with Leveling 8 (see Note 4 ). In connection with the $1.7 million payment made in the third quarter of 2020 by Leveling 8 under the promissory note, the Company paid down $1.6 million of principal under this loan, for which $1.0 million was a prepayment against the loan. As a result, the balance under this loan is now $1.9 million and the final payment will be June 30, 2022. The loan is secured by substantially all of the assets of the Company, including, without limitation, the promissory note that the Company received in connection with the sale of its cable segment in 2019 to Leveling 8, Inc. (see Note 4 ). Credit Agreement The Company has a $4.0 million revolving line of credit agreement with its primary financial lender, which matures on December 17, 2020. The line of credit requires quarterly interest payments based on the prevailing Wall Street Journal Prime Rate ( 3.25% at June 30, 2020), and the interest rate is reset monthly. At June 30, 2020, there was $2.8 million outstanding under the line of credit. Future borrowings under the line of credit are limited to the lesser of $4.0 million or the sum of 80% of eligible accounts receivable and 25% of eligible Telco segment inventory. Under these limitations, the Company's total line of credit borrowing capacity was $3.1 million at June 30, 2020. Loan Covenant with Primary Financial Lender Both the March 10, 2020 loan agreement and line of credit agreement provide that the Company maintain a fixed charge coverage ratio (net cash flow to total fixed charge) of not less than 1.25 to 1.0 measured annually. The Company believes that it is probable that it will not be in compliance with this covenant as of the measurement date of September 30, 2020. The noncompliance with this covenant would result in an event of default, which if not cured or waived, could result in the lender accelerating the maturity of the Company's indebtedness or preventing access to additional funds under the line of credit agreement, or requiring prepayment of outstanding indebtedness under the loan agreement or the line of credit agreement. Paycheck Protection Program Loan On April 14, 2020, the Company received a SBA Payroll Protection Program (“PPP”) loan pursuant to the Paycheck Protection Program under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), with its primary lender for $2.9 million. The PPP loan bears interest at 1% per annum, with monthly payments of principal and interest in the amount of $164,045 commencing on November 10, 2020, and matures on April 10, 2022. The Paycheck Protection Program provides that the PPP loan may be partially or fully forgiven if the funds are used for certain qualifying expenses as described in the CARES Act. The Company intends to use the proceeds from the PPP loan for qualifying expenses and to apply for forgiveness in accordance with the terms in the CARES Act. While the Company plans to apply for forgiveness of the PPP loan in accordance with the requirements and limitations under the CARES Act, the PPP Flexibility Act and SBA regulations and requirements, no assurance can be given that all or any portion of the PPP loan will be forgiven. Fair Value of Debt The carrying value of the Company's variable-rate line of credit approximates its fair value since the interest rate fluctuates periodically based on a floating interest rate. The carrying value of the Company's term debt approximates fair value.
