Effective date: 01 August 2026

The following text contains vital information about TCIskimmer Lite usage at your side after purchasing, so please take care reading entirely. By ticking the “Agree” tick-box during purchase you are confirming that you read and fully agreed with the following terms and conditions. If you do not agree with even single term or condition out of all listed below, then please do not proceed with the purchase.

  1. TCISkimmer Lite license is INDIVIDUAL and based on Yearly Subscription schema. License validity period started from the date license issued, not from the date you first time run the software. Extra 7 days added to the license assuming you need some time to download the software and set it up, hence effectively license is valid for 365+7 days. Expired subscription means application will not be operable until the subscription is renewed. Please note that this operation model is effective now and will be changed in future towards simplification, including multi-year subscription, bundling, etc.
  2. KYC procedure is mandatory for this product, you will be asked about your HW, SW and you have to accept general Terms and Conditions and this Terms and Conditions. No KYC – no purchase.
  3. No physical product is issued or/and posted; instead you provided with your individual downloadable copy of the TCIskimmerLite software for selected OS platform, licensed uniquely to your primary Call Sign and contest Call Sign (if it is different from primary).
  4. License is issued against your official HAM radio call sign(s). License is non-transferrable, the software can be legally used only by the operator, who’s callsign it is licensed for. The terms are slightly different based on license types and at the moment of purchase:
    • for Basic and Trial license only your primary call sign is required;
    • for Advanced and DX we will require your primary call sign and your contest call sign. If you do not possess dedicated contest call sign, then please make sure you tick the box “contest callsign same as primary” in your Account Profile.
    • Skimmer Trial can be only produced once per single account/customer. Skimmer Trial is limited for 14 days and cannot be extended.Skimmer Trial is zero price and issuing Trial license is the subject for approval, which cannot be guaranteed.
  5. Collective stations, HAM radio groups, DXpeditions, etc. are only eligible for Advanced or DX versions. We are not checking your group status on selection and checkout, the responsibility of selecting right product is yours.
  6. Each tier – Basic, Advanced and DX – has multiple OS supported: MacOS (Apple silicon and intel), Linux x64 and Windows x64 (10 and 11). You will be required to select at least one during the purchase.
  7. If you have purchased Basic license and later decided that you need and upgrade to Advanced or DX, please contact our support. Same applies if you want to upgrade Advanced to DX. Downgrading the license from DX to Advanced or Basic, or from Advanced to Basic is not supported. Upgrading the license does not reset license validity counter: this means if your purchase day is 1st of January and then you decided to upgrade on 1 of September – you will pay upgrading cost, but the validity period of you license will remain unchanged.
  8. One TCISkimmer Lite license gives you the right to run TCISkimmer Lite license on one selected PC/notebook only at the moment. Running same license copy on two or more machines at the same time is not supported. If you need to run two copies TCISkimmer Lite at the same time on two different PC, then you have to purchase second license. With one license you have and if you ordered two or more OS versions – you can freely select which one you are running at the time, with the conditions “one license for one machine at the time” met.
  9. Running second copy of the same license at the same machine is supported. This might be required if you want to use second instance of the TCISkimmer Lite for RX2 of your SunSDR transceiver. The second instance should be started with specific key and all information about the syntax, alongside with instructions for each OS is provided in the User Manual. Please note, that dependent on the Hardware, the CPU load with two running instances of TCISkimmer Lite will be twice, hence take care periodically checking to ensure you do not overload CPU to the level, when TCISkimmer Lite functionality is disrupted.
  10. Please make sure that you read Hardware Compatibility notes at product page. TCISkimmer Lite license cost will not be refunded just because you did not read Hardware Compatibility and purchased product which cannot run on your hardware/OS.
  11. You are obliged to use the software for legal purposes only. Use of TCISkimmer Lite in government or military services is directly prohibited.
