Re: RA0SMS Miniwhip bad performance on SDRPlay

Good morning from UK. From my slender electrical knowledge and past experience, I really woudn't use either of the first two pictured as they may prove a fire hazard or at least are likely/possible to overheat. I believe that You need at least 100ma to be safe, but of course higher than 100ma would ...

Re: RA0SMS Miniwhip bad performance on SDRPlay

Just picking up on what Heinrich, said - my german made psu is about the size of a small brick and freestanding, suppied by a cable - it's no "wall-wart."
Best Wishes

Re: Longwire antenna question

Probably not very helpful to you. I am UK base, but the psu was bought in Germany some time ago. It is a MW911GS IC1200 STABLE 3/6/9/12V 1200MA - never measured it's output, but has worked satisfactorily. It is on the 12V setting and I am in no way tempted to try a lower voltage setting as it may ca...

Re: Longwire antenna question

Hi I am in a rural location. The RA0SMS is set atop a metal base plate (http://www.maplin.co.uk/p/ptm-s-bracket-for-mobile-antenna-mounting-with-so239-fitting-r73hf?cmpid=ppc:gadgets_toys___hobbies:pla:google&gclid=COKR2s3D99MCFaSw7QodUZcHPg,) which provides something of a ground plane, mounted ...

Re: Longwire antenna question

Hi there For the past few days, it would appear that there is an issue with very poor HF signal propagation conditions, at least in my part of the world and if I were just making my initial antenna connections, I would not be in a rush to change them until you have had an opportunity to check on thi...

Re: sdruno recording

Further to my last, I have found that that defaulting to recording the LO frequency only results in the effect mentioned in my last when trying to play the recording back outside of SDRUno, or having left and returned to the programme.

sdruno recording

Unfortunately, using the record function in SDRUno causes any recording that I make default to recording the LO frequency - OK I suppose as long as the tuned frequency and LO are the same. However, whilst it is possible to notch out the LO spike in some ssb signals, the LO may not in any case coinci...

Re: SDRSHARP

The SDRplay support team are naturally constrained in answering queries about the use of the SDR# app with the RSP2, which is quite understandable. However, try as I might, I am unable to get the SDR# Rev. 1361/1331 to open the api or recognise the RSP .dlls. May I ask if any of this community have ...

Re: Erratic RF Gain control

From my very strictly non-technical aspect - yes, it does seem to be rather random, not behaving in a "linear" fashion - each step in either direction being inconsistent. There may of course be an explanation that is beyond my very limited knowledge. I have simply settled for whatever sett...
