Re: VFO & LO for dummies

(I don't mean to hijack this thread ... this is the closest discussion I've found that seems to potentially be discussing something thats got me puzzled.) SDRplay support said : "Note that there are 2 ways that the spectrum can be produced from the hardware (Zero IF and Low IF) - Zero IF supports th...

Excellent Technical Support

I was going-around-in-circles with my RSP1A Receiver (see my tale-of-woe here : https://www.sdrplay.com/community/viewtopic.php?f=11&t=3000) and then I sent in a request for assistance to the SDRplay Support Helpdesk Team. Steve Brightman, who is located only a few miles from me (so we can both 'see...

A Hi-Z Antenna Input For The RSP1A Receiver

For those of us with the RSP1A Receiver (I was intrigued by it having a 14-bit A/D) .... we don't have the Hi-Z antenna input that the RSP2 Receiver provides. Here is a part which looks like it might be useful : http://www.nooelec.com/store/balun-one-nine.html (a .jpg image is being uploaded showing...

Re: HF pre-selector

Dear Captain Nemo (may I please get a ride on the Nautilus sometime ?); A long time ago the ARRL Handbook had a 'regenerative preselector' for the HF bands. Given the era (1960s) it was based on vacuum tube technology but still .... a very interesting idea .... (as a regenerative amplifier is brough...

Re: Does SDRuno Software Allow For Continuous Tuning ?

It's 'fixed'. (And now 'the rest of the story' ..... Is anyone out there old enough to remember the Paul Harvey radio shows ?) After incredible support by my (friendly) local SDR repair guy (I'll let him retain his anonymity) .... What finally got my installation of SDRuno working correctly was to g...

Re: Does SDRuno Software Allow For Continuous Tuning ?

(here is a bit more information) If I unlock the LO while I have the receiver tuned to an AM station .... and then I begin to tune the receiver the audio from the AM station continues to be heard (showing that the receiver is not actually changing frequency) .... the 'background' RF spectra (all the...

Re: Does SDRuno Software Allow For Continuous Tuning ?

(I'm not familiar yet with this Forum's software so my responses will lack sophistication .... sorry.) The SDRsupport people have said (back 'up' this thread) : "If you are using a RSP, then the LO can tune between VLF and 2GHz without the need to press Stop/Start " (my response) The receiver I am u...

Re: Does SDRuno Software Allow For Continuous Tuning ?

Hello Andy; Perhaps I am 'missing' something (being a new user that seems possible) but in my experience (using the U.S. AM Broadcast Band as a training ground) I find : 1.) For the frequency display to work correctly the LO must be locked 2.) When I tune to the upper end of the Broadcast Band (1700...

Does SDRuno Software Allow For Continuous Tuning ?

Am I correct in thinking that the SDRuno software does not provide an automatic feature which allows for continuously tuning ? For example ... (I'm in the U.S.) If I begin tuning near the bottom of our AM Broadcast Band (550 kHz to 1700 kHz) .... going up-and-up ... eventually I come to 1700 kHz. If...
