What portion of the 10 meter band is available for repeater use?
The portion of the 10 meter band that has been set aside for repeaters is the portion above 29.5 MHz (from 29.5 – 29.7 MHz).
What frequency do I use on 70cm?
The 70-centimeter or 440 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio and amateur satellite use. The ITU amateur radio allocation is from 430 to 440 MHz; however, some countries, such as the United States, allocate hams 420 to 450 MHz.
What band is 10MHz?
10MHz is one of the so-called WARC bands that are traditionally left contest free. It is a narrow band of just 50kHz and is shared with the primary user. Because of the small allocation amateurs have at 10MHz, it is by agreement used only for CW and narrow band digital modes.
Is 20 meters upper or lower sideband?
Upper sideband (USB)–The common single-sideband operating mode on the 20, 17, 15, 12 and 10-meter HF amateur bands, and all the VHF and UHF bands. SSB (“sideband”, Single Sideband Suppressed Carrier) is the descendant of traditional AM.
When should I use USB and LSB?
When single-sideband is used in amateur radio voice communications, it is common practice that for frequencies below 10 MHz, lower sideband (LSB) is used and for frequencies of 10 MHz and above, upper sideband (USB) is used.
How far can 10-meter band go?
“SHORT SKIP” on ten meters is usually around 500 miles or less and normal skip propagation “Sky Wave” can vary from a thousand to several thousand miles and around the earth. During the height of a sun spot cycle, signals can be heard both near and far for a large part of the 24 hour day.
What is the 30 meter band?
The World Administrative Radio Conference (WARC) bands are three portions of the shortwave radio spectrum used by licensed and/or certified amateur radio operators. They consist of 30 meters (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz) and 12 meters (24.890–24.990 MHz).
When was the 222 MHz band plan adopted?
This band plan has been proposed by the ARRL VHF-UHF Advisory Committee. Note: The 222 MHz band plan was adopted by the ARRL Board of Directors in July 1991. Repeater inputs 25 MHz split paired with those in 927.000-927.075 or Weak signal Repeater outputs 25 MHz split paired with those in 902.0000- 902.0750
How many repeater pairs at 20 kHz spacing?
NB FM Repeater Outputs (45 pairs at 20 khz spacing) i.e. 1291.10, .12, .14, .16, etc.) We are still considering other needs, such as packet, duplex packet and other modes which may require shuffling other allocations.
When was the 50 MHz bandplan adopted by IARU?
At the IARU Region 1 Conference in Cefalu (1984) a 50 MHz bandplan was adopted for use in countries within the European part of Region 1 where amateurs had obtained a frequency allocation or assignment in the 50 MHz band.
What are the Texas VHF FM Society band plans?
The committee has agreed upon the following policy for requests for portable “emergency” repeaters: 1. The trustees should utilize UHF pairs of TX/RX 441.300/446.300, 441.325/446.325, 441.350/446.350, 441.375/446.375. These backyard pairs are available on a “first come, first serve basis” and will not be published in the repeater directory.
