EDITORIAL
Like most new things, the advent of the "personal" set, a baby version of a self-contained battery-operated portable, brings along its crop of worries. Whilst waiting at a radio counter in town recently the customer ahead of me was trying to dispose of one of these sets. He told the man at the counter that he had only bought it a month ago, but already it had used up three sets of batteries. Having a few moments to spare, I suggested that we check the current drain, borrowed a meter and did so. The drain was still a shade over 12 milliamps, although the batteries were both down fairly low. This is a fairly normal drain for sets of the type and with it a 467 type battery will last about 15 hours. The running cost works out at well over a shilling per hour. Unless buyers are acquainted with the true position about running costs these portables are likely to earn a smelly reputation, thereby spoiling what would be a further wide application of radio if handled properly. Public reaction to the price of the minimax batteries is also easy to understand. They know that a small torch battery costs 8d. or 9d. The minimax is two or three times as big and as heavy. It is expected that the price will be, likewise, two or three times as much. Unless the running costs of personal portables can be greatly reduced, they are going to go down in history as one of the worst flops in the radio business. A. G. HULL.
