I only get one weather channel, but I am way beyond range of any small craft and the one weather channel is out of a town about 8 straight line miles from me. The owner of the radio is back in town now, so I will return the unit to him and forward your messages as well so that he can decide what to do with it. If you want to contact the owner directly to see if he is willing to let it go for parts, he can be reached through me and I will forward messages to him for you. Thanks again for helping out on this problem, I really appreciate it. The charger voltage is 12V, so that the charging circuit (consisting of a couple of resistors and a diode) can loose some energy. There is 7 NiCad batteries in the pack, that gives the final voltage of 8.2 volts. In the 'specs' of the manual, the proper operating voltage is 8.2V plus/minus 10%. IMHO, as long as it only receives, i guess it can run some time without damage - but if you start transmitting, the output transistor (Q213, 2SC3101) will overheat and suffer damage rapidly. As far as i can determine, this transistor is already rather borderline for the rated max output power. If you want to give the battery pack a new lease of life, i assume you can replace the old Ni-Cad batteries with Ni-Mh cells.

It may be a bit difficult to find the right size, as the cells are only 3/4 of the length od an AA cell. I cut my pack up, after making a gypsum mold, and used it to elongerate the pack with epoxy resin.īut a bit of homework could alter the pack to accept the larger cells.

I cannot comment on the quality of other Ray Jefferson products, but my old radio has taken a terrible beating over the years - and keeps working. No EEG parameters were found to be differentially predictive between sine and pulse wave ECT.Many modern radios are made with SMD-components: they are not as resilient to environmental impacts (= salt water!) as the leaded components of my set. Postictal suppression appears to offer a useful predictor of clinical outcome of depression in BL ECT. Postictal suppression emerged as the only significant predictor of therapeutic outcome when baseline Hamilton Rating Scale for Depression and mode of stimulation were controlled for. Polyspike phase duration was significantly longer in sine wave ECT than in pulse wave ECT. regularity, postictal suppression) were manually rated by three trained psychiatrists. A total of 30 consecutive depressed inpatients who had not responded to standard pharmacotherapy were treated using BL ECT given in either sine or pulse wave mode.

The authors examined ictal EEG parameters as predictors of therapeutic effectiveness in bilateral (BL) sine and pulse wave ECT. Abstract Ictal electroencephalography (EEG) parameters in electroconvulsive therapy (ECT) for depression reportedly correlate with therapeutic response and stimulus dosage, particularly in right unilateral (RUL) ECT.
