Dear friends
My experience in the practice of dexism, today I am 83 years old, led me to
use the following equipment to obtain the best results:
Receiver: Rohde & Schwarz EK 896
Antenna coupler: 1coupler AT-1000 Global
Preamp: Ameco PT2
Sound Box: Gove SP 200
Kenwood HS-5 Headphones

>

> Telefunken E1501: has highpass filters inside, on MW is desensitised,
> bandwidth filters are poorly selected for voice understandability , needs a
> QRM free location, not mine regrettably.
>
> https://www.fenu-radio.ch/Telefunken_E1501-en.htm
>
> WJ 8711a: Audio distortion
>
> WJ8716A: I have read some reviews and it seems a very good radio, I will
> keep investigating
>
> EKD500: needs laarge antennas, it would not work correctly with my
> Wellbrook. I read that the perfomance is equal to an JRC 545.:
>
> https://www.fenu-radio.ch/RFT_EKD-500-en.htm
>
> Ten Tec RX340: At very weak signals Telefunken 1501 has a much better
> audio recovery and has clear sound. Add a SE-3 would be expensive:
>
> https://www.fenu-radio.ch/Ten-Tec_RX340-en.htm
> I would bet for the RA3701 or the 3711 ( I have not found much information

> same league. I will keep an eye on the 3701.

> I discard the EK895 the are like hen's teeth in finding one.
