07:30 to 08:30 on Saturday 13th May 2017
Special net for Heathkit equipment

 
Eight stations joined this special net; six were using DX100U sets; one station used a DX60 (with amplification); one (Pete, G7DXV) used the extremely rare combination of Comanche and Cheyenne. Here's a recording of the net and a picture of Pete's set-up. The recording was made by Ian F4VSC in Brittany; recording quality has been reduced to enable the file to be uploaded to the website.

VMARS AM Net Controller Bronek Wedzicha M0DAF located near York
Recording made by Ian Underwood F/M0YMK located in Brittany

This was a remarkable net because of its broadly excellent conditions and the wide spread of the 28 stations that took
part. If this net is an indicator of how conditions are improving for the 08:30 start, then this winter looks very promising.

VMARS AM Net Controller Keith Yates, G3XGW located near Evesham, Worcestershire


Of particular interest today is F/G1RAF, the station operated by VMARS member Derf Mockford, G8ZGK, from the sea wall
on the D-Day Gold Beach at Arrowmanches in Normandy using a Racal Syncal 30 TRA931 in AM with an output of just 4 watts.
The best reception from Derf can be heard a few minutes into Part One of the recording.
Derf was part of a team from the Royal Air Force Halton Amateur Radio Club who are visiting the invasion beaches.


This net was recorded in West Sussex

07:30 -08:40 Saturday 16th March 2016 on 3615KHz AM

Special VMARS AM Net Controller Tony Barron, G3YYH
This special net, starting an hour before the usual Saturday morning VMARS AM net, was designed to give the opportunity for low power stations, typically under 10W input, to operate in reasonably good conditions. 18 stations joined, and inevitably others attempted to join but were not heard. Stations were from as far afield as York, Den Haag, Wales, the West Country and the South East. Equipment used included WS19, WS62, Clansman 320, Collins TCS12, Codar AT5 and homebrew gear. During the previous week, there had been both CME and CIR solar events, but the propagation conditions following those events had abated before the net and conditions were stable and good for the time of year.

AM activity in the UK can be found almost every day on frequencies such as 3615KHz and 5317KHz.

VMARS hold a regular AM net on Saturday mornings on 3615 KHz starting at 08:30 local time and ending by no later than 10:30. There is usually an informal net on the frequency from around 07:30, which is then handed over to the designated Net Controller just before the controlled net is due to begin.  Anyone is welcome to call in,  there is no requirement to be a member of the Society or to be using vintage equipment; all that is required is a genuine interest in using AM .

Net Controllers ask participants not to tune up on the frequency when the net is in operation, even if you cannot hear anyone at the time.  The  Controllers will make a "tuning and netting"  period available at the start of the net and will allow gaps for stations to call in. Joining stations will be added to the bottom of the list of stations already logged and waiting their turn.



 
Below - M0TCM - The regular VMARS AM Net Control station operated from
Thorpe Camp Museum, Woodhall Spa, Lincolnshire, by Colin Guy, G4DDI.
The station presently consists of a T1509 transmitter and a choice of AR88, HRO-5T or R1475 receivers.  A fully functional 19 set is also available for emergency use.  Also visible in the picture is  a Pye FM10D Cambridge used to keep in touch with the locals on GB3FR, and a Heathkit modulation monitor to keep an eye on the T1509!


 
Below - G4GEN - Alan Morriss, regular VMARS AM Net Controller located near Nutley, East Sussex
When running the VMARS AM net, Alan uses a Wireless Set No 53 which reputedly arrived on the D-Day landing beaches on D+3, an RCA AR88 or his much loved WWII Telefunken E52 receiver


 
Below - Bronek Wedzicha, M0DAF, regular VMARS AM Net Controller located near York and seen here using his WWII Collins TCS12 transmitter/receiver at the 2014 National Hamfest held at Newark
Bronek enjoys operating the net with a home built transmitter using a pair of TT21's in the final and a National HRO for receiving
 

 

Below - Mike Duce, G4BQF, regular VMARS AM Net Controller located on Canvey Island, Essex
When Mike runs the Saturday net he uses his 1950's Minimitter transmitter and a Racal RA17 receiver, seen here in his fine collection of Racal equipment.

 

 
Below - Keith Yates, G3XGW,  regular VMARS AM Net Controller located near Evesham, Worcestershire
Keith usually operates the VMARS net with a Labgear LG300 transmitter and a National HRO receiver but he has been known to come up on a Heathkit DX100U transmitter with an RCA AR88 receiver.Keith is pictured here in front of his 1940's Marconi T1145/R1155  RAF aircraft station famously used on board Lancaster Bombers.


 
Below - Stuart McKinnon, G0TBI, regular VMARS AM Net Controller located in Kinver, Staffordshire
Stuart's main station for use on the net is an RCA ET4336 Tx and an AR88 D receiver. However, he will frequently be heard using some of his other sets, such as his Marconi T1509, a DX100U or KW Vanguard transmitters from his large collection of vintage and miltary equipment.





Below - Paul Craven, M1PVC, regular VMARS AM Net Controller located near to the  village of Hartfield in the Ashdown Forest, East Sussex.
Paul operates the VMARS net with a Heathkit DX100U transmitter in combination with a National HRO 500 receiver

Below - the temporary shack of  Tony Barron, G3YYH, located in the Cotswold Hills about 5 miles south east of Cheltenham. Tony generally uses an HRO receiver from 1946 and a DX100U transmitter, with SDR on stand-by to resolve difficult signals.

Another regular VMARS Net Controller is Tony Hibberd, G8AQN, whose station is located near Rugby, Warwickshire.
 
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).
