Better audio plus a real S-meter compared to a marl 1-2 or L type .
Have two L types , although not as good as the later RA17 C16 types or the RA 117's .
In 1983 I bought the Racal 17L (0,5 - 30 MHz)at Hoka Nieuwe Pekela. The receiver was used by the Dutch navy.
In one word an excellent receiver. Very sensitive, selective and no "overload" at all. It has no problems with spurious signals or images. The receiver is very quiet, even by modern standards and seems immune to overload.
After one hour the Racal is extreme stable. But very heavy, about 35 kg's. It's build like a (centurion) tank!
Also a very good preselector and you can calibrate the BFO. It has the following filters:
13 / 6.5 / 3 / 1.2 / 0.3 / 0.1 kHz
A minor point is that you need a good external speaker to get nice audio
And of course the smell of the tubes, very nostalgic.
But later when my wife and the first child came there was not enough space for my Racal and now it's spending his days in a little room. And now I use rather "modern" receivers like the Icom R70, R75 and Kenwood R100. But I will keep it forever and one day the Racal 17l wille be "renovated". It's a wonderful piece of equipment and when you buy one and have the room for it, buy it!!! It outperformes many modern receivers.
