Re: SDR Console and RDS logging - coming soon.

Hi everyone, I got very excited when Jim posted about the RDS logging in SDR Console. I've been testing as well and I have to report that the weak signal performance of the decoding still doesn't match that of the RDSSpy decoder - it's all down to the super-pi detector. But the decoder does work ver...

Re: HS Publications (UK) still alive ?

Patrick, A balun is not needed for impedance matching the aerial to the radio, but if you don't use a balun you will likely find a much poorer front to rear ratio than is achievable. Read K6STI's page on 88-108 MHz baluns http://ham-radio.com/k6sti/balun.htm where the first paragraph summarises the ...

Re: Elad FDM-S3

It is not just the ability to record 24 MHz - but that it has 16 bit ADC. If you want something cheaper that will record the whole FM Band in one go there is the LimeSDR mini which is supported by SDR Console v3 and is currently advertised at $159 for the bare board + $15 dollars shipping from Crowd...

Re: SDR Sharp and ELad FDM-S2

Not on an Elad but on SDR# when I've got a VAC installed for feeding RDS Spy using MPX Output and have accidentally left the Audio repeater program running on the ssme virtual audio cable. In my case that could happen if I've been using HDSDR previously for feeding RDSSpy - when you have to share on...

Enhanced coastal tropo

I'm not posting this as a DX alert as it is probably relatively local.

The 'usual suspects' are coming through but I did pick up one new transmitter, not yet listed on FMList.

On 94.0 Top Radio from Brugge with PI: 6308 and PS:TOPradio. Details can be found on Top Radio's web-site.

Who moved the start of spring?

Hands up all those who thought the first day of spring started on the 21st of March (today). Well it didn't! It started yesterday - the 20th - and has done so for quite a few years. The astronomical spring begins on 20 March 2019 and ends on 21 June 2019. The astronomical calendar determines the sea...

Re: Conditions Improving

I gave up MW DXing - due to wideband interference totally wiping out the band. I still had amakeshift MW antenna - which was good enough to monitor if ever the band became clear. Lo and behold - last time I checked a couple for days ago it was clear. And has stayed clear (so far!). So I've re-connec...

Re: Tropo Wed 13th Feb

...What you are reporting as DX are my daily regulars, many of which reach RDS levels. Lille, Egem, etc. are my locals. Sorry, just not my idea of tropo. Maybe I have just been de-gruntled. I agree - I call them semi-DX stations. I generally don't even bother to log the closer German DX stations un...

Re: Tropo Wed 13th Feb

Late evening of the 13th produced very strong/clear signals from Belgium and Holland on the vertical antenna. Totally noise free stereo (O=5) on some stations- which is very unusual. German signals were limited, generally, to under 500 km but did include some low power stations (O=1-2). The 24/7 set...

DAB from Belgium (6D, 12A), The Netherlands (9D), and France (7D, 8A, 8D) coming in with audio this evening, although Belgium on 6D looks to have co-channel interference now.

Re: Tropo Wed 13th Feb

Down in this corner of the UK the nearer German stations are coming through at RDS PI code levels at this time (15:55 UTC). Hopefully it is the start of a good tropo opening. The usual 24/7 monitoring system is running and I look forward to seeing what develops overnight. The antenna for this is a T...

Re: Analogue TV-DX logs from 1990/91

Thanks for the info Andy - FMList puts it as exactly 1200 km. RMF FM on 93.3 comes from that site.That is the furthest tropo distance I've had on Analogue TV. The best FM tropo distance was also 1200 km - from Sweden (SR P4 Kisa) in October 2015 and in 2017 tropo from Poland (Lebork) on FM at 1173 k...

Re: Quadrantids 2019

I think you will run into issues. SDR apps write a lot of data to the disk and there will be enormous contention between the two apps. No doubt memory buffering will come into play - how much memory do you have? Can't each SDR record to a different disk? Stuart Taking the 2nd point first. That's ho...

Analogue TV-DX logs from 1990/91

I just found an old diary from the time I had a 4-bay Triax BB aerial, along with fixed loft mounted aerials for Band I and Band III. Of particular interest to me is a note for 3rd Sept 1991: "POLAND Ch 36. TELEWIZJA NOCA programma 2 as positive id". Would anyone have a record of what transmitter si...

Hopefully this meteor shower will give some results. It is circumpolar - and if I interpret the star charts correctly it is highest in the sky - almost overhead at around 6 am.
