Great Rcvr, in the Hands of a Skilled Operator  Time owned: 3 to 6 months
This is the final model in the Lafayette branded, Trio built receivers. Similar to the HE-80, less the FM Mode and includes the 150-400 kHz Longwave Band instead of the 550-1600 kHz Broadcast Band. In addition, the HA-225 adds a separate 6 VAC Filament Transformer to power the Heaters of the Oscillator and Mixer Tubes, even if the receiver is off. The other improvements are a cover over the Main and Bandspread Tuning Capacitors, and a separate module for the BFO.
After recapping(all electrolytic and tubular capacitors are faulty on these receivers - due to age) and performing an alignment, the HA-225 I acquired works great. The Amateur Bands, calibrated on the Bandspread Dial, are dead on. For instance, using the built-in Crystal Calibrator to set the 40m Bandspread Dial to 7.1 mHz, I receive FT8 signals at 7.074 mHz, CW from 7.000 thru 7.050 mHz, and USA LSB Comms from 7.125 up. Everything is where it's supposed to be. The Bandspread Dial is quite accurate, to within 5 to 10 kHz on 40 Meters.
This said, this receiver requires a skilled operator to bring out its best. When receiving LSB, it's best to set the BFO one tick mark left of center. USB is one tick mark right of center. SSB and CW signals require the RF Gain to be backed off, whether the AVC is in or out. Otherwise a strong signal will pull the oscillator. This is inherent in all the Trio built, Lafayette badged communications receivers from the HE-10 in the late 1950's, to the HE-30, HA-230, and HE-80 in the mid 1960's.
Like all the receivers in this series, the HA-225 is Single Conversion. The receiver is well designed and free of images. For the ultimate upgrade, one can attach the Lafayette HE-73 PreCon, Preselector/Converter. This crystal controlled converter converts 20M, 15M, and 10M to 80M. This upgrades the receiver to Double Conversion on these bands. The PreCon also works as a Preselector on 80M-10M.
In the mid 1960's I was a preteen bitten by the Radio Bug. I picked strawberries and raspberries the summer of 1964 hoping to earn enough to purchase one of the Lafayette Receivers I saw in their catalog. I didn't earn enough, so the following summer I acquired a Paper Route. Still not enough so I settled on a Knight Kit Star Roamer. Now, 55 years later I have the Lafayette HE-10, HA-230, HA-225, HE-73 PreCon, and a 99-2502 External BFO(allows the Q-Multiplier to be used on CW/SSB signals on the HA-230).
