The Canadian Avenger is the featured aircraft with emphasis on the electronics suite. My gratitude is extended to Leo Pettipas,. Associate Air Force Historian. Air Force Heritage and History, 1 Canadian Air Division. Winnipeg, Manitoba and Ernie Cable, Shearwater Aviation Museum Historian. Their assistance helped to produce a document that is far superior to anything that I could do on my own. From this group, I would like to thank Robert Downs who provided me with technical infomation on some of the systems found in the aircraft and established a direct link between the commercial LEAR ADF-14 radio compass and its military cousin, the AN/ARD-7. It is hoped that this document will help to expand the knowledge base of a historical aircraft which had a starring role in the golden era of Canadian naval aviation. http://jproc.ca/rrp/rrp3/avenger.html -- Regards, Jerry Proc E-mail: jerry7proc@yahoo.com __________________________________________________________________ Be smarter than spam.

Band, attenuator setting etc are all the same. This has been true for years and a correction factor applied "mentally" when using the generator. Today I decided to try and calibrate the meter - the fun begins. Using the procedure in Section 18 (6) I cannot get any indication on M101 or the RF voltmeter connected to J101. Has anyone run into this, chances are I have something set incorrectly.

It MAY be, the biggest challenge you will face might be the poor insulation in the wiring, which is probably cloth-based. You should definitely replace all the caps with new ones, and if it was me, before I tried applying power to it. An isolation transformer is a good idea for working with these things. Depending on the fanciness of the power supply section, some don't even have their own power transformers, so BE CAREFUL. I have restored a number of items of this vintage, with good results. Have a ball, sounds like fun.

The only real reason for using inductance in the second pi section, and for feeding both the screens and plates of the 6F6's is to get magnetic flux in the field. If using a PM speaker, you don't need this. I see one schematic that lists 500 ohms for the field winding. Frankly, if I were substituting a PM speaker in an NC100, I'd feed the 6F6 plates from the B+ input to the plug. That should put 250-300 volts on the plates, a safe number for 6F6. I would most definitely up the 6F6 cathode resistance from 250 ohms to around 340-360, giving around 23 volts of bias. You can run those 6F6's with total cathode current down around 50 ma., fairly deep toward class B, and never no the difference----except that the 80, and the rest of the set, will love you for reducing B+ current and heat. You'll need to add resistance to get screen voltages down. I have a vague recollection that National ran 6K7 screens at 70 or 90 volts, not the usual 100 volts.

See: http://www.youtube.com/watch?v=dWtdHKrxGfA This weekend (Saturday 15 August) both the KSM wheel *and* the traffic list will be keyed using punched paper tape, the way real radiomen did it in the golden days. Those with astute ears will detect the difference in keying between the Boehme and the A-Tronix keyboard usually employed for the wheel. The traffic list will be sent as usual at 2100Z on MF and HF. During the transition from the wheel to the traffic list the famous "dotter" of earlier KPH days will be heard. The string of dots is made by the keying head between the time when the wheel tape is removed and the traffic list tape is inserted. KPH was so well known for the dotter that a satiric cartoon drawn by a ship's RO shows his idea of what the dotter must look like. In the cartoon it's steam powered with a whistle saying "toot" and the paper tape strung from a series of wheels. The weather will be sent electronically at 2130Z. If you'd like to travel with us back to those days of yesteryear tune in to KSM on Saturday. KSM frequencies are listed at http://www.radiomarine.org NOTE: To save a little power we haven't been running the 22Mc KSM transmitter or the 21Mc K6KPH transmitter lately. This seems to make sense to us given the state of the sunspot cycle. But if you think there would be a path to your part of the world on 22/21Mc just let us know. As usual K6KPH will be guarding 7050kc and 14050kc for traffic and KSM reports. However we request that stations refrain from calling from 2100Z to 2130Z as that's a busy period.

The KSM weather service at 2130Z on Saturdays has been well received with may listeners writing to say that they use the transmissions to sharpen their CW skills just as so many did during the glory days when coast stations stood shoulder to shoulder on the marine bands. But some also wrote to say they would welcome something more challenging than the weather with its predictable format. For the last couple of months Transmitter Supervisor Steve Hawes has prepared both press and weather for transmission earlier in the day during the time we are attending Services of the Church of the Continuous Wave (where pastry and coffee are served) in the engineer's lounge at the Bolinas transmitter site. Transmissions begin on all frequencies at 1000 Pacific time/1700Z. Our normal speed is 25wpm (again at the request of listeners) but Steve sometimes uses 18wpm. When I arrive at the receive site at about 1200 Pacific time/1900Z Steve throws control over to me as I put the wheel on the air for KSM and activate K6KPH. If you enjoy copying a little Morse on a Saturday please tune in. The frequencies are listed on our Web site at http://www.radiomarine.org .
