122 GHz

2022-01-25T12:50:39Z

Mic manager:

The UK 122 GHz allocation runs from 122,250-123,000 MHz. The band is a secondary allocation for the amateur service (no satellite allocation) and suffers from significant atmospheric loss. However as it is also designated for licence-exempt short range devices, an increasing amount of commercial equipment is becoming available for re-use by amateurs.

===Band Plan===

There is no formal RSGB band plan but current activity seems to be using 122.4GHz on transmit and IF frequencies in the 2m or 70cm bands.

Some additional information along with some 134 & 248 GHz information does feature on the
[http://rsgb.org/main/operating/band-plans/microwaves/122-134-and-248-ghz/ RSGB mmWave Page]

===Propagation===

The 122 GHz band suffers from significant Oxygen losses as it is a harmonic of the more well known 60GHz oxygen resonances. This coupled with humidity can lead to high overall atmospheric losses compared to the 47 and 134 GHz bands. Despite this, amateurs have had contacts on 122 GHz ranging from at least 20km in the UK, to over 100km in Australia.
The current UK DX record is almost 36km, set on 7-April-2021.

===Beacons===
There are a few personal beacons but currently no GB3xxx class systems

==122 GHz Equipment==

Equipment for 122GHz traditionally uses conversion to/from lower bands. However the latest advances in silicon technology have also been harnessed by amateurs inc 122 GHz radar sensor chips proving to be very popular as the basis for CW/SSB kits/modules.

===122 GHz Kits===

Here is one implementation of the VK3CV project courtesy G1EHF, mounted behind a surplus 50GHz link dish:

[[File:122GHz_B.jpg|400px]] [[File:122GHz_A.jpg|400px]] [[File:122GHz_C.jpg|400px]]

===122 GHz Antennas===
Many small horns and dishes are readily usable. The very high gains create beamwidths of less than a degree which necessitates careful alignment and pointing. Thus it is not unusual to see some equipment having co-mounted rifle-sights to assist setting up for QSOs.

Simple conical horn antennas can be made from cake-icing nozzles and the PME range of stainless steel ones (readily available from eBay or local kitchenware shops) will give a gain of about 21dB at 122GHz. All the nozzles in the range have an aperture of 16mm and only differ in the diameter of the throat (corresponding to the diameter of the icing thread produced). The PME 1.5 nozzle is a good starting choice for 122GHz.

Regular satellite TV offset dishes have been found to be effective too. This set up is using a regular 60cm dish fed by the on-board 20dB horn:

24 GHz

2020-09-04T19:50:44Z

Mic manager: /* 24 GHz Power amplifiers */

The UK Primary 24 GHz or 1.2cms allocation is 24.000 - 24.050 GHz with the centre of the narrow band operating segment at 24.048 GHz. Wideband operation is centered around 24.025 GHz. In addition there is further secondary spectrum between 24.050 and 24.250 GHz of which the first 100 MHz is not currently permitted to be used in the UK. Consequently the Primary allocation is recommended for all current and future usage.

===Band Plan===

See the [https://thersgb.org/services/bandplans/html/rsgb_band_plan_2017.htm RSGB 24GHz band plan] for full details.

===Beacons===
There are a number of narrow band beacons in the 24GHz band - see [http://www.beaconspot.uk/beaconm.php?bandmhz=24048 this page for an up to date list].

==24 GHz Equipment==

The easiest way to get on 24GHz is to modify 23 or 26GHz telecom link equipment.

A very good example of this is by G1EHF which shows how simple it is to get on 24 GHz.

[[File:DA_24GHz.JPG|400px]] [[File:DA_24GHz_side_view.JPG|400px]]

Internally, the transverter largely comprises DMC modules from a ex-23GHz microwave link. The synthesiser and filter have been retuned to the 24GHz band, with the preamplifier, intermediate amplifier and power amplifier connected in series. These are then reversed using a coaxial transfer switch between RX and TX, providing a reasonable noise figure on RX and around 100mW on TX. An MM94P mixer and retuned filter are common to both RX and TX paths.

The transverter runs from a single 12V battery and uses an FT817 on 430MHz as the IF. The antenna is by RFS with a gain of around 36dBi.

[[File:DA_24GHz_internal_view.JPG|400px]] [[File:DA_24GHz_front_view.JPG|400px]]

This transverter runs from a single 12V battery and uses an FT290 on 144MHz as the IF.

[[File:24GHz_internals.jpg|400px]] [[File:24GHz_trial.jpg|400px]]

==== Putting a system together ====
Perhaps the first thing to get is your dish as this determines the hardware form factor of your system.

Then collect and test the modules, typically these will be:
*Local Oscillator block plus multiplier
*Receive module
*Transmit module
*Antenna changeover system - waveguide or high quality SMA relay.

===Local Oscillator requirements===

To operate on the NB segment at 24,048.2 MHz the following LOs are required:

*144 MHz IF = 24048 - 144 = 23,904 MHz (/2 = 11,952 MHz)
*144 MHz IF = 24048 + 144 = 24,192 MHz (/2 = 12,096 MHz)
*432 MHz IF = 24048 - 432 = 23,616 MHz (/2 = 11,808 MHz)
*432 MHz IF = 24048 + 432 = 24,480 MHz (/2 = 12,240 MHz)

LO generation can alternatively be initiated at lower frequencies with the availability of the versatile Analogue Devices Fractional N Frequency Synthesisers such as the ADF4351 shown below. These fully functional boards requiring just frequency and register programming data can be bought relatively inexpensively from a number of sources including E-Bay sellers. Programming data can be uploaded using a cheap Arduino (Mini) controller to send the required data to the synthesiser registers on power up. The output frequency can be multiplied up to the required LO value although it is likely that for narrowband use a more stable external Frequency Reference source for the synthesiser will be needed from for example, a Leo Bodnar GPS disciplined clock generator or a GPS disciplined OCXO.

[[File:20200903_161007.jpg|400px]]

===DMC Equipment===

DMC modules are used by a lot of operators and there is a lot of information available on the web:

*W6BY has compiled a very useful reference list of DMC part numbers = http://www.qsl.net/w6by/parts/dmc.html

===Elcom synthesisers===

A very common unit to generate the 13GHz LO (doubled to 24GHz) is to use the Elcom 1201 synthesiser available from ebay.

* G8CUB has done an excellent article describing their use = http://www.rfdesign.co.uk/microwave/Content/Elcom%20Synth%20article.pdf

===Nort Synthesized Local Oscillators===

The Nort Synthesized Local Oscillators provide a stable LO signal in the 12 - 14 GHz region at about 14 dBm. These were on sale at HamRadio 2018. More details here: [[Nort SLO]]

===Thales Alcatel 23GHz equipment===

A lot of Thales / Alcatel equipment appeared on the second hand market around 2010.

* G4NNS describes the Alcatel system and his own portable setup (currently on loan to G8GTZ) http://myweb.tiscali.co.uk/g4nns/24GBits01.html

==24 GHz Power amplifiers==
MMIC devices are available that can produce around 1W of output power at 24GHz. For example the EMM5832 device. Ready made PA's such as the Toshiba amplifier pictured come available on the surplus market from time to time. However even power levels as low as 10mW can provide useful performance when coupled with reasonable antenna gain.

2020-09-04T19:47:08Z

Mic manager: /* 10 GHz Equipment */

The UK 10 GHz or 3cms allocation nominally runs from 10-10.5 GHz but with a number of gaps/restrictions.
It is the only UK amateur microwave band available to all three Licence Levels including Foundation.
The centre of the narrow band operating segment is at 10368 MHz.

===Band Plan===
Frequency ranges available are:-
*Amateur Service: 10.000-10.125 and 10.225-10.475 GHz
*Amateur Satellite: 10.450-10.500 GHz

See the [https://rsgb.org/main/operating/band-plans/ RSGB band plan] for further info

===Beacons & Repeaters===
There are a number of narrow band beacons in the 10 GHz band - see [http://www.beacons.org.uk www.beacons.org.uk] for an up to date list. There are also a number of licensed TV repeaters in the band which provide useful signals - see the
[https://www.ukrepeater.net/tvrepeaterlist.htm?filter3=3cm ETCC web site] for more details.

==10 GHz Equipment==

3cms is popular and a great band to get an introduction to microwaves and several equipment manufacturers make transverters for 10GHz. Opportunities also arise from widespread availability of low power radar modules which can be used for NBFM contacts.

This portable set up is GPS disciplined for frequency accuracy and only develops about 850mW at the antenna feed. The antenna is an 80cm offset Sky dish and the transverter is driven by a 144MHz FT290.

122 GHz

Mic manager: /* 122 GHz Kits */

The UK 122 GHz allocation runs from 122,250-123,000 MHz. The band is a secondary allocation for the amateur service (no satellite allocation) and suffers from significant atmospheric loss. However as it is also designated for licence-exempt short range devices, an increasing amount of commercial equipment is becoming available for re-use by amateurs.

===Band Plan===

There is no formal RSGB band plan but current activity seems to be using 122.4GHz on transmit and IF frequencies in the 2m or 70cm bands.

Some additional information along with some 134 & 248 GHz information does feature on the
[http://rsgb.org/main/operating/band-plans/microwaves/122-134-and-248-ghz/ RSGB mmWave Page]

===Propagation===

The 122 GHz band suffers from significant Oxygen losses as it is a harmonic of the more well known 60GHz oxygen resonances. This coupled with humidity can lead to high overall atmospheric losses compared to the 47 and 134 GHz bands. Despite this, amateurs have had contacts on 122 GHz ranging from at least 20km in the UK, to over 100km in Australia.

===Beacons===
There are a few personal beacons but currently no GB3xxx class systems

==122 GHz Equipment==

Equipment for 122GHz traditionally uses conversion to/from lower bands. However the latest advances in silicon technology have also been harnessed by amateurs inc 122 GHz radar sensor chips proving to be very popular as the basis for CW/SSB kits/modules.

===122 GHz Antennas===
Many small horns and dishes are readily usable. The very high gains create beamwidths of less than a degree which necessitates careful alignment and pointing. Thus it is not unusual to see some equipment having co-mounted rifle-sights to assist setting up for QSOs.

Simple conical horn antennas can be made from cake-icing nozzles and the PME range of stainless steel ones (readily available from eBay or local kitchenware shops) will give a gain of about 21dB at 122GHz. All the nozzles in the range have an aperture of 16mm and only differ in the diameter of the throat (corresponding to the diameter of the icing thread produced). The PME 1.5 nozzle is a good starting choice for 122GHz.

24 GHz

2020-09-04T15:43:15Z

Mic manager: /* Elcom synthesisers */

The UK Primary 24 GHz or 1.2cms allocation is 24.000 - 24.050 GHz with the centre of the narrow band operating segment at 24.048 GHz. Wideband operation is centered around 24.025 GHz. In addition there is further secondary spectrum between 24.050 and 24.250 GHz of which the first 100 MHz is not currently permitted to be used in the UK. Consequently the Primary allocation is recommended for all current and future usage.

===Band Plan===

See the [https://thersgb.org/services/bandplans/html/rsgb_band_plan_2017.htm RSGB 24GHz band plan] for full details.

===Beacons===
There are a number of narrow band beacons in the 24GHz band - see [http://www.beaconspot.uk/beaconm.php?bandmhz=24048 this page for an up to date list].

==24 GHz Equipment==

The easiest way to get on 24GHz is to modify 23 or 26GHz telecom link equipment.

A very good example of this is by G1EHF which shows how simple it is to get on 24 GHz.

[[File:DA_24GHz.JPG|400px]] [[File:DA_24GHz_side_view.JPG|400px]]

Internally, the transverter largely comprises DMC modules from a ex-23GHz microwave link. The synthesiser and filter have been retuned to the 24GHz band, with the preamplifier, intermediate amplifier and power amplifier connected in series. These are then reversed using a coaxial transfer switch between RX and TX, providing a reasonable noise figure on RX and around 100mW on TX. An MM94P mixer and retuned filter are common to both RX and TX paths.

The transverter runs from a single 12V battery and uses an FT817 on 430MHz as the IF. The antenna is by RFS with a gain of around 36dBi.

[[File:DA_24GHz_internal_view.JPG|400px]] [[File:DA_24GHz_front_view.JPG|400px]]

This transverter runs from a single 12V battery and uses an FT290 on 144MHz as the IF.

[[File:24GHz_internals.jpg|400px]] [[File:24GHz_trial.jpg|400px]]

==== Putting a system together ====
Perhaps the first thing to get is your dish as this determines the hardware form factor of your system.

Then collect and test the modules, typically these will be:
*Local Oscillator block plus multiplier
*Receive module
*Transmit module
*Antenna changeover system - waveguide or high quality SMA relay.

===Local Oscillator requirements===

To operate on the NB segment at 24,048.2 MHz the following LOs are required:

*144 MHz IF = 24048 - 144 = 23,904 MHz (/2 = 11,952 MHz)
*144 MHz IF = 24048 + 144 = 24,192 MHz (/2 = 12,096 MHz)
*432 MHz IF = 24048 - 432 = 23,616 MHz (/2 = 11,808 MHz)
*432 MHz IF = 24048 + 432 = 24,480 MHz (/2 = 12,240 MHz)

LO generation can alternatively be initiated at lower frequencies with the availability of the versatile Analogue Devices Fractional N Frequency Synthesisers such as the ADF4351 shown below. These fully functional boards requiring just frequency and register programming data can be bought relatively inexpensively from a number of sources including E-Bay sellers. Programming data can be uploaded using a cheap Arduino (Mini) controller to send the required data to the synthesiser registers on power up. The output frequency can be multiplied up to the required LO value although it is likely that for narrowband use a more stable external Frequency Reference source for the synthesiser will be needed from for example, a Leo Bodnar GPS disciplined clock generator or a GPS disciplined OCXO.

===DMC Equipment===

DMC modules are used by a lot of operators and there is a lot of information available on the web:

==== Putting a system together ====
Perhaps the first thing to get is your dish as this determines the hardware form factor of your system.

Then collect and test the modules, typically these will be:
*Local Oscillator block plus multiplier
*Receive module
*Transmit module
*Antenna changeover system - waveguide or high quality SMA relay.

===Local Oscillator requirements===

To operate on the NB segment at 24,048.2 MHz the following LOs are required:

*144 MHz IF = 24048 - 144 = 23,904 MHz (/2 = 11,952 MHz)
*144 MHz IF = 24048 + 144 = 24,192 MHz (/2 = 12,096 MHz)
*432 MHz IF = 24048 - 432 = 23,616 MHz (/2 = 11,808 MHz)
*432 MHz IF = 24048 + 432 = 24,480 MHz (/2 = 12,240 MHz)

LO generation can alternatively be initiated at lower frequencies with the availability of the versatile Analogue Devices Fractional N Frequency Synthesisers such as the ADF4351 shown below. These fully functional boards requiring just frequency and register programming data can be bought relatively inexpensively from a number of sources including E-Bay sellers. Programming data can be uploaded using a cheap Arduino (Mini) controller to send the required data to the synthesiser registers on power up. The output frequency can be multiplied up to the required LO value although it is likely that for narrowband use a more stable external Frequency Reference source for the synthesiser will be needed from for example, a Leo Bodnar GPS disciplined clock generator or a GPS disciplined OCXO.

24 GHz

Mic manager: /* 24 GHz Power amplifiers */

The UK Primary 24 GHz or 1.2cms allocation is 24.000 - 24.050 GHz with the centre of the narrow band operating segment at 24.048 GHz. Wideband operation is centered around 24.025 GHz. In addition there is further secondary spectrum between 24.050 and 24.250 GHz of which the first 100 MHz is not currently permitted to be used in the UK. Consequently the Primary allocation is recommended for all current and future usage.

===Band Plan===

See the [https://thersgb.org/services/bandplans/html/rsgb_band_plan_2017.htm RSGB 24GHz band plan] for full details.

===Beacons===
There are a number of narrow band beacons in the 24GHz band - see [http://www.beaconspot.uk/beaconm.php?bandmhz=24048 this page for an up to date list].

==24 GHz Equipment==

The easiest way to get on 24GHz is to modify 23 or 26GHz telecom link equipment.

A very good example of this is by G1EHF which shows how simple it is to get on 24 GHz.

[[File:DA_24GHz.JPG|400px]] [[File:DA_24GHz_side_view.JPG|400px]]

Internally, the transverter largely comprises DMC modules from a ex-23GHz microwave link. The synthesiser and filter have been retuned to the 24GHz band, with the preamplifier, intermediate amplifier and power amplifier connected in series. These are then reversed using a coaxial transfer switch between RX and TX, providing a reasonable noise figure on RX and around 100mW on TX. An MM94P mixer and retuned filter are common to both RX and TX paths.

The transverter runs from a single 12V battery and uses an FT817 on 430MHz as the IF. The antenna is by RFS with a gain of around 36dBi.
