There are Drake noise blankers and then all the rest. I agree on the NB-7. This also applies to the noise blankers used in the TR-4 series including the TR-6 and the R-4C, SPR-4 receivers. Although the R-4B has a decent noise blanker, it is nowhere near as effective as the ones just mentioned. All are very similar in design if not IF frequency. However, I must say the noise blankers in the Yaesu FT-920 and FT-100mp mkV are also very effiective. The only drawback in the Yaesu rigs is the front end filter is a bit wide and limits the effectiveness of the blankers due to strong adjacent signals. Like you, I am severely limited by noise at my QTH. One of the things that helps with a single source of noise is the ANC-4 now manufactured by Timewave. My "noise" antenna is usually a Hustler 6-BTV mounted on the ground in my back yard. It can be tricky to adjust however. Another solution is the use of a beam antenna. It turns out a north-east pattern is pretty good from 20m - 10m. Th! e types of noise I get are many and range from defective street lights, electrical appliances in the various homes around me (touch lamps being the worse), and line noise. I've also had problems with in-home burglar alarms. One of those was kind of fun as I told the home owner I knew when he wasn't home :-) That got fixed in a hurry! It seems that whenever I track down one source and get it fixed, another appears to take its place! I'm not ready to give up yet. -------------- Original message -------------- From: Thom LaCosta <[EMAIL PROTECTED]>
