Key UHF bands in the UK include: 70 Centimeters (430-440 MHz): Highly popular for local communication, especially in urban areas where building penetration is important. Repeaters: Similar to VHF, UHF repeaters extend the range of handheld and mobile radios.
Aug 17, 2024 · Notes: HF Bands: High Frequency bands (1.8 MHz to 30 MHz) are commonly used for long-distance (DX) communication. VHF/UHF Bands: Very High Frequency (30 MHz to 300 MHz) and Ultra High Frequency (300 MHz to 3 GHz) bands are popular for

The Seventy Centimetre (70cm) band within the UK is 10MHz wide commencing at 430MHz and extending through to 440MHz. The band is allocated to the Amateur Service with Secondary status and includes additional restrictions in parts of the band. 1. Power Restriction:In 430-432 MHz, the maximum peak envelope power in this area of the band is 40W (16dBW...
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. Althou...
430.000 – 432.000MHz All Modes
The lower 2MHz of the band is allocated to modes with a maximum transmission bandwidth of 20 kHz. Here you will find a variety of Internet voice gateways, high speed digital links and digital repeaters. Between 430.8250 to 430.9750MHz are located the 7.6MHz repeater system output channels RU66 to RU78. The area between 431.000-432.000MHz is used for voice Internet linking but it is recommended that you consult with the RSGB Emerging Technology Co-ordination Committee before considering use of...
432.000 – 432.100MHz Telegraphy
This 100kHz wide sub-band is allocated to modes with a maximum transmission bandwidth of 500Hz. Earth-Moon-Earth (EME) activity using CW may often be found in the bottom 25kHz of the band. Occasionally you may also hear JT65C EME activity around 432.065MHz.
432.100 – 432.400MHz Narrowband Modes
Narrow-band modes with a maximum bandwidth of 2.7 kHz are always located at the low frequency end of any VHF or UHF allocation. This is where you will find Morse (CW), telephony (SSB) and machine generated mode (MGM) activity such as JT65C and FSK441. In addition to the separate CW sub-band this is the area of the 432MHz band where operators make long-distance (DX) contacts.
One of the attractions of using the 432MHz band is that with 10MHz of bandwidth to play with there are so many different ways of using this amateur service allocation. Some of these aspects include FM and Digital Voice (DV) using either simplex or repeater channel systems. You’ll also find activities that are using Morse (CW), telephony (SSB) and m...
At this Ultra High Frequency (UHF) you are going to be very disappointed with results if you only use a small vertical aerial fed with a considerable length of very thin coaxial cable. There’s no getting round it but at these frequencies you must use a good aerial and even more importantly you must use a high quality low-loss feeder cable. Anything...
On this UHF band the only propagation mode that you will normally encounter is some form of tropospheric enhancement. Surprisingly though these events occur much more frequently on this band than on lower frequencies. The only downside is that there is less activity on 432MHz compared to 144MHz or other popular bands. But when the band does open up...
