Re: T4XB/R4B Transceive problem


 

¿ªÔÆÌåÓý

Well I put the R4B on the bench tonight (with Linda¡¯s help) and the verdict is in. The R4B¡¯s crystal is cleared of any wrong doing.?

? ? ?That would tend to make the culprit appear to be one or both T4XB filters having changed significantly. At this point I¡¯m thinking of putting them back on the shelf. They operate fine when used as separates. It¡¯s just the transceive function that is off. I may just offer them here in the near future since I have the TR7/RV75 and a TR4C both of which work great thanks to a good friend of mine. ?

Tony, AK4K Crystals has the 5.595-MHz crystal available as a stock item. Taking into inflation, the $32.00 price tag isn't "that" bad!
