About OL1TWR

The call sign OL1TWR is a pilot and project call sign of the České rozhledny / Czech Lookout Towers program. It serves for joint activations, rule testing, program promotion, and engaging new operators.

Purpose and Use

• Tower Activations – joint outings and demonstrations from attractive sites.
• Program Presentation – hamfests, kids’ events, contests, and field demonstrations.
• System Testing – scoring, logging, API, and rules.
• Bonus Call Sign – every QSO with OL1TWR gives hunters extra points.

Call Sign Loan

OL1TWR can be temporarily loaned (usually 1–3 days) to registered activators who want to help promote the program. If the call sign remains free, the loan can be extended.

Conditions: valid license, activity in the České rozhledny program, and adherence to hamspirit and regulatory rules. When using OL1TWR, the activator must always state their own call sign in the OPERATOR field.

How Activation Works

We operate portable from or near towers, respecting visitors and the site. Common modes: SSB, CW, FM, sometimes digital. A typical QSO includes RST report, tower reference code (e.g. OKR-0133), site name, and locator. Hunters reply with their report and call sign – enough for a valid QSO.

Diplomas and Points

Each QSO with OL1TWR gives the hunter bonus points counted in the diploma system. Activators earn standard points per rules. Upon reaching thresholds (50, 100, 200, 500 QSOs etc.), numbered PDF diplomas are issued.

Logs and QSO Confirmation

Logs of OL1TWR are stored in the central database at rozhledny.eu. Confirmations are mainly via QRZ Logbook, with optional paper/electronic QSL on request.
