433.000

Postby ACL » Wed Aug 17, 2016 10:01 pm

On a regular basis I receive a repeater on the above frequency. It's too weak and the morse too fast for me to decode but isn't my local NR repeater which often keys a minute later. Looking online the only possibilities it could be are Milton Keynes or Kent but am certain this is too far to be received at my Norwich location under normal/flat conditions. Has anybody got any idea what this weak repeater could be?

Milton keynes would be my best guess. Why not record the ident on your phone and look for the last two characters - CK or MK - so the final letter will be dat-di-dah, but before that comes day-dah for M or dah-di-dah-dit for the C. this should be obvious with a few listens. If you get stuck, record it and stick the clip on soundcloud or similar and we can read it for you. With an outside aerial and decent location 50m is doable - more than that seems a bit of a push - what is your line of site distance to MK?

Thanks G4RMT. I will record it and try and decipher the last two characters as you suggest. My line of sight would be roughly 150KM North West Norwich to Milton Keynes. I have a dual frequency white stick situated outside at the highest point of a three story house. It's strange as PO from Ipswich on 2m only just breaks the squelch and doesn't register on the S meter so my reception is fairly standard to average. It's certainly nothing special so will be pleasantly surprised if it is Milton Keynes. However there was a slight lift last night as I received ON0FF on 2m.

You sure that it's not just a temporary weather thing because 150k is a long way for a low gain aerial system even on top of a tall house on a mountain. Best bet is to record it I think. P

Yes your right. This morning I received 3 repeaters on that frequency although there was a lift on. One was NR, one was Kent and a weak one. I will try and record it however I will have to wait for conditions to return to normal in order to get a valid result. Just out of interest I also received ON0FF last night .

You can barely get MK outside of Milton Keynes so unlikely to be that

If there is a lift on, it could travel 100's of miles with ease. I have worked a German amateur via a 2 meter (144mhz) repeater in France from Norwich using a handheld radio & the 70cm repeater in Boston Lincolnshire use to be on 433.000 too & that could not be worked from the other side of the Wash, but could sometimes be worked with a fully quietening signal from Norwich when a lift is on.
Here in Norwich we get European users on both the 2 meters & 70cm repeaters most summers during lifts as they know they open to them during lifts.

Hopefully the link will work. There is a lift on but during fairly flat conditions I'm confident this is what I often receive.

Well it's Charing Kent, GB3CK. This morning it was blasting in but now back to normal levels for Norwich. I guess it's the sea path that makes it receivable during normal/ flat conditions. What I find strange is that I can barley receive IH Ipswich on 433.100 under normal conditions but I can receive this.
