Earlier on while pruning my 4m slimjim (it is now on song, more on this at a later date) I noticed my MFJ-259B was acting strangely.
On certain ranges, the unit is displaying nonsensical frequencies at the bottom end of the TUNE knob’s travel. On the 114-170 range the unit displays “0.0000 MHZ” until about 119MHz is reached. Tuning LF on the 27-70 range the unit gets to about 28MHz and suddenly displays 140.60MHz. You have to tune all the way back up to about 38MHz before the thing regains its senses.
I know a lot of people in SOTA use the same bit of kit, so before I go delving further,with precision capacitors and resistors and seeing if I can make any sense of it all, I thought I’d have an ask here and see if the tale is a familiar one. In this instance it would seem that Google in not my friend!
Any and all suggestions gratefully RX’d!
