Portable Review

The information below is not guaranteed to be free of errors.

1. Introduction

This guide

only includes well performing portables. Among the poor performers were

numerous single-conversion units lacking SSB and drifty analog units with digital frequency

counter displays (no memories). Note: the

S350DL is decent on MW (large ferrite rod). Portables

are organized by Size in cubic inches. The “Mem” columns below reflect only SW memories.

2. Double Conversion

Double conversion helps reduce images. Portables without audio phasing (

ss-SAM) need

two bandwidths: to reduce adjacent interference simply engage the narrow filter and detune by

one or two kHz. Without SAM, good SSB is necessary to reduce heavy selective fading distortion.

Positive attributes are green; negative are yellow; and deal-breakers are red.

The

KA1101 has few memories and no SSB. The E5, YB-80, and G4000A cost more than

the SW7600GR which has SAM. The

YB-400PE has good audio but poor SSB and needs six “AA”

type batteries. The costly

ATS-909 has good SSB but poor whip sensitivity and easily breakable

parts (stand and battery cover). Some

E5 units are not as sensitive as the DE1103. Missing from

the chart are the mediocre performing

SW35, ATS-505P, ATS-606AP, and ATS-818ACS.

The

DE1102 and DE1103 are classics: earphones, AC adapter, rechargeable batteries,

external antenna, and cloth pouch are included. The DE1102 is an ultra-portable with good SSB

and “

automatic tune scanning” (ATS). The DE1103 combines good whip sensitivity with good

immunity to external antenna overload. The downside: the DE1102 has SSB only in the “

memories. The DE1103 has no 5-kHz tuning knob step and the tuning knob doubles as the

volume control. I recommend purchase of the Degen radios through tquchina or Liypn on eBay.
