Substantial Doubt about Going Concern [Text Block]	Note 2 – Liquidity and Going Concern The Aeroflex litigation (see Note 13 to the Condensed Consolidated Financial Statements) did not result in a favorable outcome for the Company, despite our belief that we committed no wrong doing. These condensed consolidated financial statements have been prepared in conformity with GAAP, which contemplates continuation of the Company as a going concern. As reflected in the accompanying balance sheet for the period ended June 30, 2019, the Company has recorded estimated damages to date of $5.4 million, including interest, as a result of a jury verdict associated with the Aeroflex litigation. The Company has filed for an appeal (see Note 13). In June 2019, Bank of America agreed to extend the Company’s line of credit until March 31, 2020 (see Note 8). While the Company’s operations and profitability have significantly improved, the Company may not have sufficient resources to satisfy the judgment if we are not successful in our appeal. We have no commitment from any party to provide additional working capital and there is no assurance that any funding will be available as required, or if available, that its terms will be favorable or acceptable to the Company. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year of the date that the financial statements are issued. The jury found no misappropriation of Aeroflex trade secrets, but it did rule that the Company tortiously interfered with a prospective business opportunity and awarded damages.

The jury also found that the former Aeroflex employees breached their non-disclosure agreements with Aeroflex.

The Court denied the Company’s motions and awarded Aeroflex an additional $2.1 million of punitive damages.

This $2 million bond amount will remain in place during the appeal process (See Note 13). The Company believes it has solid grounds to appeal this verdict. The appeal process is expected to take several years to complete. However, the Company cannot predict the timing or the outcome of the appeal. The Company believes it has sufficient cash and financing in place to fund its plans for the next twelve months, exclusive of any determination that may result from the Aeroflex litigation, due in part to recent large orders it has received that has returned the Company to profitability.

Note 2 – Liquidity and Going Concern

The Aeroflex litigation (see Note 13 to the Condensed Consolidated Financial Statements) did not result in a favorable outcome for the Company, despite our belief that we committed no wrong doing. These condensed consolidated financial statements have been prepared in conformity with GAAP, which contemplates continuation of the Company as a going concern. As reflected in the accompanying balance sheet for the period ended June 30, 2019, the Company has recorded estimated damages to date of $5.4 million, including interest, as a result of a jury verdict associated with the Aeroflex litigation. The Company has filed for an appeal (see Note 13). In June 2019, Bank of America agreed to extend the Company’s line of credit until March 31, 2020 (see Note 8). While the Company’s operations and profitability have significantly improved, the Company may not have sufficient resources to satisfy the judgment if we are not successful in our appeal.
