Re: RSP1A Longwave sensitivity
Hi. I have to say that my RSP1A works very well indeed right down to 60kHz. For a while I used a CR100 receiver with a modified Front end with two EF95 pentodes as the RF amplifiers. I use a modified Wellbrook loop and have had some excellent DX. Initially I thought the RSP1A was overly noisy and lo...

Re: MegaDipol MD300DX
Hi. As this antenna works on the E-field its performance will be bad for people like me in a crowded RFI area. I get noise from power line adaptors, ADSL, SMPS, and all the other sources. I've used all sorts of antennas longs wires EWE antenna and active dipole. Only magnetic loops work here and vir...

Re: ALA1530LN and the tale of four NDB's
Hi Andy. You'll see me on the Golbourne vintage Radio forum. VRAT as well. I used to be on the United Kingdom Vintage Radio forum too but had a big fall out and was kicked off. I do have many Murphy sets from the V310 V410 V320 etcetera, I've limited space and a good few items have been donated to a...

Re: ALA1530LN and the tale of four NDB's
Hi Andy. Sounds like a good mod. I'm more into Long and Medium Wave DX plus air band which I use a different aerial. I occasionally listen to other stuff and I've found the modded Wellbrook is good up to 100Mhz which is handy for me. I'm now constructing a 1.2meter loop using 15mm copper tube and tw...

Re: ALA1530LN and the tale of four NDB's
Hi. I've used an ALA1530 for some time. There is a weakness though and that is where the loop enters the amplifier, under the outer alloy "loop skin" there is ferrite and in strong winds this can crack and make the loop defective. A new amplifier assembly can be bought from Wellbrook for around £100...

Re: SDRuno S-Meter = S5 With No Antenna
Hi Glovisol. Thanks for the reply and the tips. I have given this a try and yes I do see an improvement. My own set up from the aerials are: Modified Wellbrook ALA1530 loop, Long wire via balun and dedicated aerials for the frequencies I monitor (Band 1 Analogue TV, Low FM, Airband and 446PMR along ...

Re: SDRuno S-Meter = S5 With No Antenna
Hi. I've been reading the thread with interest, to be fair I'm somewhat confused. Over the years I've had many receivers through my hands and was a Radio & TV engineer to trade with all the relevant qualifications. In a good comms receiver you would perhaps have two stages of RF amplification, frequ...

TVsharp or other related software on RSP1A
Hi. This is my first post and thread on this forum so please bear with me if this has been discussed before or is not possible. Firstly a little history. I am an EX TV engineer and have a collection of 405 line TV's and vintage Radio sets. I have always been a SWL and am into a little DX on medium w...
