There is, however, fairly frequent simplex operation on the 70cm band, and it occurs primarily. The national simplex calling frequency for 2 meters is 146.520 MHz. Generally, any frequency between 144-148 on 2 meter is pretty active. 70cm national national simplex calling frequency band would be 446.000 MHz. Common courtesy on national calling frequencies is to establish a contact and then move onto another frequency for others to. The UK 432MHz band (70 Centimetres) has considerably more bandwidth than all the amateur radio bands between 136kHz to 28MHz, 50MHz, 70MHz and 144MHz put together. With 10MHz of bandwidth from 430- 440MHz there's plenty of room for everyone. However there are particular problems associated with band planning within this area of the spectrum. 222.350 Mhz is the National FM simplex calling frequency. A 20 Khz spacing matrix is used on this band. Other frequencies in the 223.600 to 223.850 Mhz range are also used for FM simplex. 440 Mhz (420-450 Mhz, sometimes called 70 cm band) 446.000 Mhz is the National FM simplex calling frequency.

CALLING FREQUENCIES-- Courtesy of Rob Bellville and the Lincoln Amateur Radio Club 2M CW. 432.2 and up 70cm FM. 446.000 MHz 33cm CW/SSB. Simplex frequencies whether MF, HF, or VHF are primarily used for Distress, Urgency, Safety, Calling, and Ship to Ship communications. Choosing an appropriate simplex frequency can be a little tricky, since it depends on whether your region uses the 15-kHz or 20-kHz channel spacing. Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550. A second block within the 70cm band (445.00 - 447.00 MHz) is reserved for "Auxiliary and Control Links, Repeaters, and Simplex (Local Option)". Again, your OpenSPOT is a good fit, here. If you start at 445.0125, and go to 446.9875 Mhz, with 12.5 KHz spacing, you end up with the following list of possible frequencies.

This project hereby presented is a complete HAM radio simplex 'smart' repeater, built around a Motorola GM-350/950, Arduino NANO board and a WINBOND audio recording integrated circuit.. The repeater was built to work on the 4m band, in order to promote activity and provide testing facility (by providing on-air S-reports) Motivation :. Simplex The standard VHF frequency is 146.52 and UHF is 446.000. You will hear very little traffic in most areas, and some areas have additional frequencies. As mentioned, repeaters will give you the best chance of hearing ham traffic. 70cm Stand Alone Repeaters. 70-cm calling frequency. 6) Additional FM simplex frequencies may be designated regionally. Note 1 - Includes all other emission modes authorized in the 9 cm amateur band whose necessary bandwidth does not exceed the suggested bandwidths listed. Simplex operations on the 70cm band are not quite as common as those on 2 meters, owing mostly to the fact that 2 meter. The Arizona 2m band plan shows a range of frequencies to be used for FM simplex, such as 146.400 – 146.600 MHz along with a note that says the Even 20 kHz Frequencies should be used. So that means the preferred simplex frequencies in this range are 146.40, 146.42, 146.44, 146.46, 146.48, 146.50, 146.52, 146.54, 146.56, 146.58 and 146.60 MHz. For 146.520 MHz FM, it is to any other clear FM simplex channel. Note 5: Seven frequencies on a 20 kHz channel raster: 144.37, 144.39, 144.41, 144.43, 144.45, 144.47 and 144.49. Occupancy is to occur onlywhen available Digital frequencies within the sub-bands 144.9 – 145.1 MHz and 145.59 – 145.79 MHz are exhausted. Consult with your local. If this cannot be accommodated on a 70cm pair, one of the standard 2m or 70cm repeater pairs may be used as a final choice. • System Fusion repeaters operating in digital only mode coordination requests should first be attempted in the 70 cm band using one of the 12.5 KHz splinter pairs. ... Of particular note, some simplex frequencies listed. At these higher frequencies, coaxial cable attenuates rf more rapidly and drastically than lower HF frequencies. An example using RG-58 type coax on 10Mhz vs 400Mhz increases loss by about 10db per hundred feet! 2. Use a high gain outside antenna if at all possible. We use those simplex freqs as well around here for YSF. But in my notes I have 145.562 (didn’t note the reference for that). Centre frequency for EME, globally coordinated frequency allocations exist above and below 432.0 MHz. 432.100 – National. CW Calling Frequency (2) 432.200 – National.

There is, however, fairly frequent simplex operation on the 70cm band, and it occurs primarily. The frequencies to be used for DMR simplex are defined in the UK Amateur Radio Band Plan. We share the analogue allocation as it’s noted FM/DV (Digital Voice) however DV users are not to use the FM calling channel as another has been allocated specifically for digital. Note that on the 2m and 70cm lists, I have replaced the FM calling channel. Simplex Frequencies & Usage Occasionally you want to use your radio without having to use a repeater. We have that covered. You can program your radio with the following information, and use your radio in Simplex mode, no problem. The admit criteria is your choice, but this is what it means. your states 70cm band plan is below... you can use any freq inside the simplex range with a 25khz spacing. 440.9000 – 441.0750 Simplex & Packet (25 kHz spacing) so 440.900, 440.925, 440.950 and so forth till you get to 441.0750. 445.9000 – 445.9750 Simplex & Packet (25 kHz spacing). Simplex The standard VHF frequency is 146.52 and UHF is 446.000. You will hear very little traffic in most areas, and some areas have additional frequencies. As mentioned, repeaters will give you the best chance of hearing ham traffic. 70cm Stand Alone Repeaters. Choosing an appropriate simplex frequency can be a little tricky, since local practice varies. Across all of North America, 446.000 MHz is the National Simplex Frequency (also referred to as the calling frequency). In most places, the channels immediately adjacent to 446.000 MHz are used as simplex frequencies, spaced by 25 kHz. Below are the recommended simplex frequencies to be used with DMR in United States and Canada. In addition to this information, please note the following radio configuration items: Admit Criteria: Please set this to “Always”. In Call Criteria: Please set to “TXI” or “Always”. CC = 1. TG = 2 (for most radios this does not matter) The.
