[TenTec] adding xtal filter to the Orion

[nq4i at contesting.com]

Hi Barry. It would be a band specific filter with about 5 khz of response. Sherwood Engineering made a special order version abt 20 years ago. The good thing about the Orion is it is one of the cleanest transmitters made. Right now my signal leve from the second station is approximately s4. Reducing that by 40 db or more would open up the other rcvr a lot. So the filter would be before every stage in the rcvr.   Rick

Do you mean install a filter somewhere other than the 9Mhz roofing filter
slots?
