Re: Automation/remote control?

Points well taken about TeamViewer. Again, for my rather narrow application it wouldn't have been a problem but for more extensive use I certainly see where RDP is a better option. Give AnyDesk a try. It's from former Teamviewer staff members and many tests confirmed fast response and high data com...

Re: SDRuno - Rig Syncronization

DIGITAL however - no good. The rig doesn't change mode at all. That would be OK except after clicking SDRUno DIGITAL I can no longer put my FTdx3K into DATA-USB. Everytime I try it gets setback to USB. Yes, seems so. SDRuno goes to LSB when DIG-L is sent from the rig and to USB when DIG-U is sent. ...

When you launch SDRuno.EXTIO?
BTW: Funcube pro+ is not fully supported. It shows an error message that setting RF & IF gain is not possible. But it basically works. (I only have an FCD pro+, no idea how other Funcubes work.)

Re: HP Laptop Brick noise

Yes, I've been seriously considering building a filtered and regulated power supply. Yes, good idea. But you have to consider the high amperage the laptops often need. E. g. my 8 year old Lenovo (non-gamer, standard office laptop!) consumes up to 15 A at 23 Volts. I also seriously thought about bui...

Re: HP Laptop Brick noise

Laptop power supplies can be very nasty. This is not related to the brand. I owned both HP and Lenovo laptops and the PS of both were a desaster. The Lenovo PS even made reception of digital DAB+ radio impossible when it was on while the radio was in the same room. I also tried to denoise them by en...

Re: Random wire questions

As a LOG is easy to build I made some experiments the last days. The image shows a 4 x 5 m LOG and a 14 m wideband magnetic loop side by side on my Anan Angelia (portion of the 49 m band). Without a preamp the LOG is almost unusable. I added an old preamp with a PGA 103+ (which I had in my tinkerbox...

Re: Great experience with PAR Electronics EF-SWL

Hi Andy, I am using two wideband magnetic loop antennas as well. One has 14 m circumference, the other one 5 m. The amplifiers are homebrew (LZ1AQ style, but not using AF transistors). In the beginning I also assumed that magnetic loops will pick up less noise than other types of antennas as many re...

Re: Great experience with PAR Electronics EF-SWL

Hi, as someone said: "Even a wet spagetti in the antenna socket is working from 0.01 Hz to 50 GHz. You just have to define what "working" is." Maybe for your purpose an EWE could be a choice. It does not necessarily take much room. It is directional and you might have to invest s...

Re: Great experience with PAR Electronics EF-SWL

LNRPrecision say it is a 1-30 MHz rx antenna. Anyone can post some performance figures of such antenna vs frequency range? I mean, this is a "short" wire (about 12 m), it performs the same at 10MHz and at 1MHz? I dont think so. I have some experience in DIY random wire antenna, and I know...

Re: Proximity to computer

Computers in the vicinity of receivers always can cause trouble. Make sure that the antenna is as far away from the house as possible and insert a common mode choke directly at the antenna input of the receiver to block common mode noise induced into the coaxial cable by switching power supplies and...
