What I would like to see in future versions.

First off, a great big thank you to Simon for this fantastic software. His constant work on updating Console shows his passion for radio. After using Console for over a year with my Airspy HF+, I just have a wish list I hope to see someday.
I would like to see a manual notch.
A scan function like SdrUno.
Maybe more color scheme choices for the entire program not just waterfall.
Just a personal nit pick. I never liked the line going thru the zero digit. I know why it was done long ago, but your not going to have the letter O in a number frequency. It makes the frequency display look crowded and not visually appealing.
Maybe an option to move the GUI around. Things like put the frequency display, filter pane things like that were you want.

As I said just a wish list. Console is a great piece of software. I use it and my Airspy HF+ more than my RSP1A and Uno.

Hi,

 

  • Manual notch – I find the automatic notch works well, I may add a manual option in the future.
  • Scan – will happen sometime, but will be written correctly and support multiple SDRs scanning simultaneously and include Audio / IQ logging.
  • Colour schemes – I would like this as well but it’s very, very time consuming!
  • I’ve just added and option to replace slash zero 0 with O so the default is slash zero. This will be in 3.0.13.

Yes, thanks, Simon. I agree with the desire for manual notch. I could stop using other software then. The implementation of manual notches in HDSDR is perfect, IMNSHO.

Seconded.

One annoying  thing I find is when I get a very narrow but strong birdie in the middle of the passband of a weakish broadcast FM signal I am trying to recieve. The capture effect means that the weak FM signal is blocked.

It would be good to be able to manually notch out the carrier and eliminate it from the demod. There is a plugin on SDR# that does this.

Ah,

 

That’s a good reason for a manual notch, I can think of others.

 

Will have to look at this when I get time…

I thought Simon’s software “learnt” what it looked like and reduced it accordingly, but I may be wrong.

 

I gave up using various dongles/receivers that had a centre spike as I have a very strong data signal bleating away from a radio system  installed on an electricity transformer about 100 metres away from the house.

This 153MHz signal is enough to cause the centre spike on what ever type of SDR software to increase and decrease in sympathy with data transmissions no matter what frequency I wish to look at. I wonder therefore if you have a very strong carrier somewhere causing an overload.

 

The SDR RSP2pro and several dingledangles being particularly prone to misbehaving at VHF (70MHz up) in that manner.

Nick,

 

Airspy HF+ Discovery is probably your best bet if suffering from strong local signals. Did you think about a band stop filter? My problem is a lack of signals, not an abundance 😊 .

Investigate putting in an open circuited 1/4 wavelength chunk of coax across your transmission line. If you make it a tad short and add a couple thin wires a couple cm long you can twist/untwist/trim the wires to put the notch right on the 153 MHz signal.

I also had a problem with 153 MHz interference and got a filter from this chap in the USA:

http://www.parelectronics.com/amateur.php

http://www.parelectronics.com/vhf-tn152-156uk-specs.php

Seems to work well, and more importantly for me, passes 432 MHz with very little loss.

I also experimented with a Chinese duplexer filter used end-to-end as a double notch filter:

https://www.satsignal.eu/Radio/2m-filter.html

A quarter-wave stub may not have enough pass at 145 MHz.

Cheers,
David

I am considering such an HF+ Discovery, but really not much point when my minimum noise floor on hf is at the -70dBm level.

Where the noise drop to almost acceptable levels it is in covered in closely spaced spikes (see attached for a plot from the Perseus).

From 24 MHz up to beyond 435Mhz $kyQ boxes, insecurity systems (cameras) and PLA systems flood the spectrum.

I’ve taken down the 144/432 stuff as it was unusable so the 153Mhz pager issue is relatively minor these days.

 

Thanks Mr David for the url for the American filters. I vaguely remember one of the Hungarian or Slovenian specialist sites also had some.

 

 

Anyway, Simon, my problem in the main is also a lack of signals…….

 

Thanks all

That noise is really nasty Nick.

I tried several aerials and the best is an 80m dipole fed with around 50 yards of coax.

I intend to rig up a ferrite rod (borrowed from a portable radio) on a 20 foot pole using a single emitter follower transistor and tuned with a varactor diode but I don’t know how good this will be in the HF region. Maybe someone has tried a remote ferrite rod?

My noise floor is around -115dBm using the dipole but with lots of spikes and rubbish, certainly a lot better than your QTH..

For HF I like the Andrus best followed by the SDR Play. Not sure if the Andrus is still available?

My apologies if this has already been tried, but you might insert a fixed 20db attenuator at the input to the Perseus and see if the spectrum drops by 20db. If it drops more than 20db, then the noise is due to overload. The extreme noise level around 10mhz seems unnatural to me.

Seconded.

One annoying  thing I find is when I get a very narrow but strong birdie in the middle of the passband of a weakish broadcast FM signal I am trying to recieve. The capture effect means that the weak FM signal is blocked.

It would be good to be able to manually notch out the carrier and eliminate it from the demod. There is a plugin on SDR# that does this.

Hi Tony

Yes that has been tried along with other radios with the same results.

I used the Perseus here for illustration as it is an HFSpan utility (Simon – hint) that allows one to quickly assess noise levels / antenna responses and many other uses. Very easy to use.

The big lump at around 10MHz appears to be VDSL leakage

 

@Allan – I have walked all around the garden to find a quiet spot. The current magloop is in the quietest place I could find. I have also mapped out the noise sources in the neighbourhood.

One neighbour has been very helpful in removing his reliance on his $kyQ box mains networking and was amazed at the improvement moving to a wireless mesh network.

Shall we say other neighbours are less helpful.

 

I am waiting on advice from RSGB and Ofcom on the next step but not holding out much hope.

 

AN improvement to one of the hidden features….a decent strip chart recorder. I am always wanting to look for variation is signal amplitude particularly at vlf (SIDs) and any current method that does not involve saving files and plonking them into another piece of software to plot would be an advantage.

 

But I recognise Simon need a holiday, one where he leave the computer at home.

 

 

..and remotes into it to post pictures

 

 

Thanks all

Nick – g4ogi

My apologies if this has already been tried, but you might insert a fixed 20db attenuator at the input to the Perseus and see if the spectrum drops by 20db. If it drops more than 20db, then the noise is due to overload. The extreme noise level around 10mhz seems unnatural to me.

I am considering such an HF+ Discovery, but really not much point when my minimum noise floor on hf is at the -70dBm level.

Where the noise drop to almost acceptable levels it is in covered in closely spaced spikes (see attached for a plot from the Perseus).

From 24 MHz up to beyond 435Mhz $kyQ boxes, insecurity systems (cameras) and PLA systems flood the spectrum.

I’ve taken down the 144/432 stuff as it was unusable so the 153Mhz pager issue is relatively minor these days.

 

Thanks Mr David for the url for the American filters. I vaguely remember one of the Hungarian or Slovenian specialist sites also had some.

 

 

Anyway, Simon, my problem in the main is also a lack of signals…….

 

Thanks all

Nick,

 

Airspy HF+ Discovery is probably your best bet if suffering from strong local signals. Did you think about a band stop filter? My problem is a lack of signals, not an abundance 😊 .

I thought Simon’s software “learnt” what it looked like and reduced it accordingly, but I may be wrong.

 

I gave up using various dongles/receivers that had a centre spike as I have a very strong data signal bleating away from a radio system  installed on an electricity transformer about 100 metres away from the house.

This 153MHz signal is enough to cause the centre spike on what ever type of SDR software to increase and decrease in sympathy with data transmissions no matter what frequency I wish to look at. I wonder therefore if you have a very strong carrier somewhere causing an overload.

 

The SDR RSP2pro and several dingledangles being particularly prone to misbehaving at VHF (70MHz up) in that manner.

 

 

Regards

Nick

Cavity filters or helical resonators?

I also had a problem with 153 MHz interference and got a filter from this chap in the USA:

Seems to work well, and more importantly for me, passes 432 MHz with very little loss.
I also experimented with a Chinese duplexer filter used end-to-end as a double notch filter:

A quarter-wave stub may not have enough pass at 145 MHz.

========================

Judging by the size, not cavities for the 153 MHz notch.

The Chinese duplexer ones are cavities, although compact ones.

Back on the original topic - support for multiple dongles for multiple receivers over a broader range. Like the output and input of a 5 mHz split repeater system for example.
