Each IG Zoom meeting has the callsign of the person facilitating it clearly shown (other than the Friday meetings which are hosted by Kevin).  The routine is that people contact the facilitator beforehand if they wish to join a particular group - the facilitator will send out the joining details by e-mail immediately prior to the session to those who have expressed an interest.

G4BUE Amateur Radio Sale


After 47 years of being a hoarder and building up a large store of amateur radio equipment, sadly I have reached the stage of life where we have to down-size to a smaller house with less land where I will not be able to make use of, or have the room to store, much of my equipment.  I am therefore offering it for sale before, perhaps, donating it to a club, or even scrapping

Whilst I am happy to package and send smaller items through the mail, I do not have the time to despatch the larger items which will only be available to personal callers.  I have a large amount of other amateur radio equipment, that is too numerous to list separately, and most of which will be offered free to personal caller purchasers.

I haven´t priced each item because I don´t have the time to research what each item is worth etc, but if you let me know anything you are interested in, then I will send you a postage / shipping cost, and I am sure we can come to an agreement on the price.  Most of the equipment can be sold cheaply as I just wish to dispose of it.

Please email me at if you would like more information about something or would like to visit and look at what I have.  I am retired and am generally available most of the time.

I am adding new items all the time, so please look back from time to time.  I will delete items as I sell them.



I am also selling our QTH and have put the details on my website above.  I would love to split the estate agent´s commission with a radio amateur purchaser (and save me having to dismantle the towers, antennas and station), or split the commission with someone who introduces a purchaser to me.

Please feel free to publicise the url of my amateur radio and QTH sales in your club magazine, club forum and anywhere else where it will be seen by persons likely to be interested in it


The government has set in place conditions designed to mitigate the spread of the Covid-19 Coronavirus. In compliance, The Medway Amateur Radio and Transmitting Society (MARTS) cancels all club weekly and other meetings until further notice. This effective closure is likely to be for a period of twelve weeks or more.

The weekday morning club net at 9:30am on 144.650MHz will continue and could allow members to remain in contact.

It is planned that a similar net take place on Friday evenings starting at approximately 19:30hrs local time and running probably for a couple of hours. Colin G6PBS has offered his service as controller, using G2FJA.

Please join in; 144.650MHz will be the preferred frequency but search elsewhere if that frequency is in use by priority or other users.

Also, please keep an eye on this 'NEWS' section where club notices may appear from time to time.

Still available, but soon going to the Great Tip in the Sky.

MARTS Morning Net
The club operates a morning net during weekdays from 0930hrs to about 1030hrs on 144.650MHz. All are invited.
