Hi Allan,

Your attachment comes through just fine. There was simply no attached file in message/63732. Also, .jpeg would be fine.

I do notice the attachment has .jpeg rather than .jpg
Could it be that the .jpeg isn't linked to a program on your computer?
I've re-attached it above as a .jpg

Hi Max,

I have the same problem in not being able to view the attached picture in

Hi Allan
 
Thanks for response. Tried two other browsers same thing. It's weird because viewing the message in the list of messages it has a paperclip next to the thread title (see picture below), but in the message itself absolutely nothing, no placeholder, paperclip, link. Nothing. (see pic again) I think it must be something to do with how my subscription is set up but not sure what!
 
I'm sure I've seen loads of attachments in the past with no issues, and I didn't change anything, so not sure what's going on.

Hi George

Good luck with that..

If you have not already done this try below..

Car battery, no sdr but “ normal radio 2m ssb radio” ( normally easier to hear the noise on am/ssb than fm)
Turn off power to your house..does the noise go?? HOPEFULLY yes..( best to do this while Wife in the middle of watching tv for best effect. Guess how i know!)
If noise goes..unplug everything but power to house on..then one by one start switching things on intill you find offending item..INCLUDE all lighting!

Or if Simon is correct you could just first try router or pc..( if your lucky.)

Here..it was the fridge/ freezer..then the kids electric scooter charger then the dishwasher and washing machine ( even when off by the switch.. ok unplugged.) oh and a tv..

If not on your property then you have an issue..getting your neighbours to power down their houses is an ask, and then telling them to replace their offending equipment is a bigger ask..( leading to being asked to @£;8 off.)

If its not your property it could be mains bourne..in which case you can do things... if rf bourne then moving antenna may help..or a directional antenna..( pointing in clear direction.)

I have much experience of this..( i run 3 phaser boxes, 6 loop antennas, massive mains filtering, common mode chokes in coax etc..)

But remember your first job is to check your place! ( and hope its from there)

Thank you for those kind words Simon. Jean's cancer finally won the battle, just a couple of weeks short of our 44th wedding anniversary and 49 years to the day we met. I thought it was 50 but my daughter pointed out that it would have made her 14 years old! My kids are now both over 40 and far from the vultures I might have hinted at. I simply remind them they own exactly I cupboard , I toilet and half a shed each and they can fight over her David Cassidy album and the contents of the kitchen junk drawer! We are all adjusting to the new situation and the kids want to make sure I can keep living here and are falling over themselves to make sure I am comfortable and have every mod-con, including a rotatable cardioid loop. That might now be next year though as my son's squadron goes on a deployment in a few weeks and I wont see him until next year. At least this time he'll be a bit closer (and warmer) than the Falklands!

Re: Cannot view attachments?

I can see that picture Max but I have noticed problems on other occasions.

Instead of just left clicking on the attachment try a right click and Save (to Desktop say)

Sometimes a “jpeg marker” is said to be missing so try opening the picture with another viewer.

There are also built-in security measures within web viewers to prevent you opening attachments so try a different program, Firefox or w,h.y.

I sometimes do not see attachments sent by other members in their messages (viewing in the web app - I don't subscribe to email delivery).

So for example, in the recent post by George NJ3H, in his first message he says "see attached picture" but for me (on the web viewer) there is no picture or attachment:
https://sdr-radio.groups.io/g/main/message/63732

Any ideas why this may be? Others are commenting so they can presumably see it!

I checked my subscription settings but I don't see anything obvious.

Thanks for looking

Re: Elad S2 2-Meter Reception

Allan Isaacs
 

Hi George

I just took a street view look around Redmond and I wonder if an air conditioning unit might be responsible for the noise?

I notice you have lots of suppliers and one offers Daikan units which I assume is Daikin?

I was asked to sort out interference to VHF comms on a local ferry operating here on the Solent and it turned out to be from a Daikin air conditioner. To reduce costs they’d bought a standard commercial unit rather than one with a marine spec.

The thing used a chopper chip type STR-L472 which radiated VHF interference that was rock steady with one spike right on top of their ship-shore channel.

You have a lot of unsightly mains distribution cables around there and these may be radiating noise but if you can find a portable VHF radio and one of your interfering signals is stable enough you might be able to pinpoint its source?

http://www.radiomuseum.co.uk/emc.html

That particular pcb had tracking for lots of mains filtering but half was strapped over probably to reduce costs.

“But lots of other chopper power supplies are available”

Cheers

Please see the attached picture.

One will note the large amount of signals (I call it it interference) displayed across the portion captured.

Does anyone have a clue as to what might be causing this?

I see a similar view using an RSP DX with SDRuno.

Any thoughts would be most welcome.

Considering it is optimized for broadcast FM you can expect it to be comparatively numb on 2 meters. But, still, you have that noise. Isolating it is often not easy considering that there may be multiple sources.

When the long wire fell down I didn't bother putting it back up because of

I'm now thinking of getting a TinySA to detect and analyse interference

My suspicion is my neighbour has an unused smart meter which is messing up

I'm on my own now in a  5-bedroom modern house. The second floor is one large attic room, half guest bedroom, half shack. I no longer TX but I have 3 analogue radios and two SDRs.
One problem I have I is that since my wife passed away last month, technically half the house belongs to our two children who are constantly reminding me of that fact. Well, they can pay for half the maintenance
My current antenna feeders come into the house at the bedroom end of the top floor and there is plenty of excess. It will be a simple matter to push/pull the feeders out and pop them through a new hole into the living room two floors below.
Planning for the future if I find I can no longer climb the stairs.

Not far off our current house Tom
2 actual bedrooms
4 more for radio collection plus conservatory (=2nd workshop + around 50 more radios) Double garage = main workshop + a few hundred more radios and shack The main difference is there's an 80m dipole and a long wire which has come adrift.
No cellar (which would have been for wine if we had one)

There is a fishing line called Power Pro by Shimano. The 0.76mm stuff has a breaking strain of 95kg and does not stretch. It weighs next to nothing, comes in moss green and is very stealthy. Don't leave it lying around because it will cut you in 2.

It is made of dyneema, and while not cheap it is cheaper than what typical ham outlets will charge you.

Allan,

Hamish, GM4SFW knows a pilot who has a simple way of doing this.
Several antennas were placed in high trees.
If I remember correctly the reel of fishing line was mounted on the quadcopter.
This was mentioned in WSPR "chat" so no record.
I note several videos on youtube, maybe worth a look.
