Regular NETS Details
Special Nets
On this page you will find details of radio nets run by the Vintage & Military Amateur Radio Society and by members under their personal arrangements. These nets are NOT exclusively for VMARS members. All licenced amateurs are most welcome to join in and all we ask is that you follow the purpose of the net, for example by using A.M., USB or LSB where specified. Scroll down the page for more information.
Special Nets
All Special Nets are 3615 Khz Amplitude Modulation 07:30 local UK time unless otherwise stated
The Society holds a number of controlled Special Nets which are designed to encourage the use of specific types of vintage and home brew equipment. These nets take place, usually but not exclusively on a Saturday, from 07:30 UK local time on 3615KHz and run for one hour, following which the frequency is handed over to the VMARS Net Controller for the regular Saturday A.M. net at 08:30.
Details of forthcoming Special Nets are published here and in the monthly VMARS News Sheet. Some examples of previous nets are also reproduced here to provide an idea of the type of interests covered.

Saturday July 20th 2024: Anything military.
Saturday August 17th 2024: Anything civilian
Thursday 10th October 2024: QRP – 07:30 – 08:30 3615KHz: A.M. QRP Net – 10 watts or less, even a lot less
Normandy Landings Beach Zone Expedition June 2024
VMARS members join the 80th anniversary commemorations
The following French ANFR issued call-signs were used during this expedition at the various organised locations over the period of 6th – 15th June 2024. Frequencies in use were 3615KHz for Amplitude Modulation working in the mornings from around 07:30BST and 7070KHz for USB* working from around 12:00.
*Note. Under licence conditions there are no restrictions on the mode of operation used on the 40m band that preclude the use of Upper Side Band. The reason for operating USB is beacause the military equipment used by many stations on the net only have Upper Side Band functionality
Visits to the above sites were made with advanced agreements and arrangements with the museums and site owners and comply with all health and safety measures specified by them

Note of interest: – Using advanced communications for D-Day net backup
Recent solar activity at the peak of sun spot cycle 25 has caused periods of severe disruption on HF radio links. Because of the importance of the 80th D-Day anniversary commemoration station TM80PB located at Pegasus Bridge near Caen, and the desire of the 2024 expedition crew to maintain communications in the event of radio propagation drop out, it was decided to set up a remote station in the UK that could be operated from the Normandy beaches. Rich Bamber, M0XRB set up a remote operated Flex 6400 radio at RAF Windrush, a former WW2 flying training station on the Oxfordshire/Gloucestershire border, connected to a 15m mast with an 80m Inverted Vee aerial used on the 3615KHz AM and 7070KHz USB operating frequencies for the two weeks of activity.. The location is in a very low noise rural environment but it has no internet available for remote control. Rich set up a 5.8GHz microwave link between RAF Windrush and his works office, about 10.7 Km away, where he has access to a 100mB up/down internet connection. The arrangement allowed UK based frequency monitoring over local French Wi-Fi or over 4G mobile telephone connections. While the operator was in Normandy, the station was in England and operated under the callsign GB1RAF when transmitting. Although propagation did suffer on several occasions the remote station was necessary on receiving only a few of the weaker stations making contact with TM80PB and not being received directly in Normandy.

Pegasus Bridge Museum – TM80PB. Early morning on June 6th 2024. The CMP lorry is loaded with fully operational WW2 wireless equipment and is in position here parked alongside the original Caen Canal bascule bridge in the museum. By prior arrangement with the museum, a 15 metre tall Inverted Vee Half Wave aerial for 80m operation was erected for communications with AM stations on a controlled net beginning at 06:00 local time on 3615KHz. The net was run by Paul, M1PVC from his home QTH in East Sussex and lasted for almost 5 hours attracting 77 call in stations.

The station will be operating in Normandy for a few days until 15th June at various locations which had significance in the 1944 Normandy landings. For direct contact with the CMP vehicle listen on 3615kHz A.M. from around 07:30 BST and on 7070kHz USB during the day. Some efforts will be made to link up on 51.700mHz F.M. but these will be dependant on 6m propagation.

Martin, M0MGA operating a Wireless Set No.46 used by Beach Masters on D-Day
Wireless Set No.46. A crystal controlled man-pack built by EK Cole at their factories in Woking and Southend-on-Sea during WWII. Water resistant and used by British paratroops and by Beach Masters like Captain Colin Maud R.N. on D-Day for controlling beach landings. Three crystal controlled channels in the fequency range of 3.4 – 9.1 Mc/s and about 700mW RF output on AM and up to 1.5 watts on MCW. The set has six valves which include 2 x ARP12’s, an ARP37, an ARTP2,an AR8 and an ATP4 in the final. Power originally came from 150v and 3v batteries but VMARS users usually employ a small 6v battery inverter to supply these voltages when operating the set as a portable man-pack. It can be used with a whip aerial or with a wire aerial through a 40pf capacitor to achieve longer ranges. When conditions are right, VMARS users have frequently achieved good point to point contact between WS.No.46 sets over distances in excess of 200 miles (320Km) using wire aerials on 3615Kc/s. Probably the best British man-pack of WWII

On Thursday 13th June the CMP radio truck and equipment was invited to take part as a publicised exhibit of the Juno Beach Centre, the Canadian Normandy museum. This was a pre-organised visit which was promoted by the museum and publicised in their advanced promotional campaign. This was a fitting display and practical use of the Canadian built lorry and of the Canadian made wireless equipment installed inside, as well as an interesting practical demonstration over several hours making direct radio contact with stations in England & Wales, France, Belgium and the Netherlands using the ANFR issued callsign TM80JUNO.

SSB nets
The society also runs SSB nets. A USB net takes place each Wednesday at 20:00hrs local time on 3615KHz +/-QRM to provide an opportunity for those who wish to use their unmodified military sets which operate in USB only. There is an LSB net on Friday evenings to encourage members to keep in touch on-air. This takes place at 19.30 and uses LSB on 3615KHz +/- QRM.
Special on-air events
From time to time, the Society runs special events, generally on the 40m, 60m and 80m bands, which specialise in use of vintage equipment or to commemorate some historic event with “wireless” connections. These are advertised to members in the News Sheet, and also on the Society’s website.
The VMARS call-sign is M0VMW
The SRS Nets
The Dutch Surplus Radio Society run AM and SSB nets for vintage enthusiasts, full details are on their website here .
Other AM Activity Frequencies
AM activity is increasingly found on a number of other bands, in particular: 5317KHz, 7143KHz, 14286KHz, 21425KHz and 29000 – 29150KHz. There are several local AM nets in the UK on topband.
FM Frequencies
For mobiles working into VMARS events, 2m calling in on 145.500MHz (S20) is usual, before QSY to a working frequency. At event locations where military equipment is in use, suggested FM “Centres of Activity” on VHF are 51.700Mhz, 70.425MHz (70.450MHz calling).
CW Practice Sessions
CW practice sessions are run by Colin, G3TSK in Somerset and Keith G3XGW in Gloucestershire.The practice sessions take place on Mondays and Fridays starting at 09:00 local time and last about 30 minutes. The frequency is around 3.546MHz. Speeds are approximately 14, 16 and finally 18wpm. Listeners are invited to email G3XGW to be added to a group email to receive texts for checking. Keith’s email address is correct in the VMARS members list and on QRZ.com. The practice sessions are not nets, although brief reports will be acknowledged at the end of the session (in CW, of course!).
