WS-19 Wave meter
What does the wave meter for the 19 set look like? I see some on offer now and again and think I’d like to pick one up.

A bit of an arm waving generalization, James, but a British ‘Wave Meter’ is equivalent to a ‘Frequency Meter’ in North America. A useful piece of test equipment that can be used with a large variety of wireless/radio equipment.
Equipment labelled as being a Frequency Meter is by far and away, the more likely piece of test equipment you would find being used to service a 19-Set in Canada or the USA. Of all this equipment, perhaps the best known here is the BC-221. They come in a variety of AC and DC versions, but the AC ones are the most flexible as a shop tool. You can find them online easily enough, but you need to find one that still has its original, matching chart. Each unit was custom calibrated to a chart. You can certainly buy modern Frequency Meters but they tend to be far too sensitive for calibrating older radio equipment that really does not need that degree of accuracy. I picked up a nice, complete BC-221 locally at an HAM Fest years ago. An AC Model and it is a nice addition to the bench. David |

They were normally only issued to net control stations, as the other sets would be tuned to that signal. It contains a dual-frequency crystal (1MHz and 100kHz) plus a variable frequency oscillator that allows the operator to set his frequency as required. The original unit came in a wooden transit case that contained the headset and instruction manual, etc. Spare vibrator, valve, and dial lamps were fitted inside the unit. A later version was made in a 2-part metal case with rubber seal to protect it from damp when not in use. Judging by the serial numbers, a very large number were made - 570467 has been noted. Be careful when buying one: common modifications are to remove the vibrator and either build an AC supply into the unit, or run it from a 6.3 volt heater transformer for amateur radio use. (They sometimes fetch extremely silly prices on various auction sites. I have no idea why.) Chris. |

What you really need for your installation is this (first pic) but the British one looks like this (second pic).

Thanks Bruce . I had no idea of what our friends were talking about . So much so in fact that i have one ( Canadian ) and was playing with it recently to familiarize myself with the tuning of my set in the back of the Wire-5 box. Nice piece of kit and useful to tune precisely to a freq. The dial on the MKIII is quite coarse i find .

More photographs.
In wooden transit/storage case: https://www.royalsignals.org.uk/photos/transit7.htm A new one! https://www.royalsignals.org.uk/ws62/classd.html I think I've seen the 'metal plate' working instructions for one somewhere. (I have the water-resistant case version somewhere, must look it out.) Chris. |
