    Spain: General authorization for 2.4 GHz

    Spain's national amateur radio society URE reports the regulator has agreed to allow amateur use of 2400.050 to 2409.500 MHz to access the E'hail-2 / QO-100 geostationary satellite

    A Google translation of the URE announcement reads:

    Since the State of Qatar sent the geostationary satellite Es'hail-2, the first of its kind to be used by radio amateurs, to space on November 15 of 2018, the URE satellite (AMSAT) raised the possibility of requesting the Administration the free use of the entire segment granted for radio amateurs in Spain and not only segment 2316-2332 MHz.

    The Administration, responding to the request submitted by the URE, has developed the present resolution, which authorizes until September 26, 2019, to the holders of radio amateur authorizations, the emission of the amateur radio satellite service from 2400.050 to 2409.500 MHz. For single-sideband telephone communications, with a maximum eirp of 1500 watts, from authorized amateur radio stations located anywhere in the national territory.

    1500 Watts? Its going to be tough to be a bird in Spain.

    Yeah but that includes all the narrow beamwidth antenna gain too which can easily be 20-30 dB..

    It's being nice to the birds. In the US, there's no limit on EIRP. Even a 10 foot dish is capable of 6 MW (Megawatts) if fed with a legal 1500 watt amplifier. If you can fit it in your backyard, a 30 foot dish can do 60 MW EIRP.

    Most folks are using a 1 meter dish or so on QO-100. Only 3.75 watts at the antenna equals 1500 watts EIRP.

    I would love to see an amateur radio power amplifier of 1.5KW working on 2.4 Ghz, especially the price tag... :D

    Yes, it's a pretty tall order. But the technology is advancing due to interest in solid-state microwave ovens and industrial heating. You can buy fairly inexpensive 250 watt transistors today. Some QO-100 DATV operators are experimenting with this device.

    $270 for the module on Digi-Key.

    My model airplane controller , transmitter uses 2.4 GHz. here in America on the AM band, how is this going to work out?

    I am curious about the impact on neighboring WiFi networks starting channel #1 at 2412 MHz.
    Even heavily shielded microwave ovens (@ 2450 MHz) leaking out less than 1 milliwatt have been known to cause havoc.

    This is the reason behind the current 100 mW power limit in Sweden.

    Amateur radio is simply considered as just another short-range device, and consequently is subject to the same power restriction for
    co-existence reasons.

    There is an on-going lawsuit about raising the limit, which the regulator fights nail-and-tooth.
    They are quite confident about winning the case, by using the legal argument that the public good (=WiFi)
    has precedence over the needs from an insignificant minority.

    This is probably a sign of the times, and more assaults on the amateur UHF/microwave spectrum are to be expected in the future.
