The BEST of the 1970s
|
Time owned: more than 12 months
|

I have owned the Hy-Gain 3750 since new in 1977 and outside of replacing the final amplifier tubes (S2002 aka 6KD6) have never had a problem! This transceiver has it all and performs well even by modern standards. Though it is a "pre-warc" radio, it has a 10 mhz position that can work on transmit as well. It covers 160 meters and there are positions for the addition of two other bands with proper modification. The receiver has a very pleasant agc system and a notch filter that actually works effectively! The sensitivity and dynamic range are more than adequate for serious DXing - the 3750 hears everything my Icom IC-781 hears. The transmitter has a built in speech processor which is adjustable and very effective. It is not a QSK radio, but the T/R switching is very quiet. I have had many radios through the years and this is the only one that has stayed in the shack for the long haul. In addition to its high performance, it is probably one of the best looking transceivers ever to be produced.

Great radio

I own a HY-GAIN 3750, 3855 VFO, and 3854 spkr. It is an excellent radio, very well built and works great. no drift at all after a 15 minute warm up and 125 watts output. the tubes are listed as S2002 and seem to be a very rugged tube. must have been top of the line back then. WB5TMD

Quiet & sensitive Receiver
|
Time owned: more than 12 months

The Hy-Gain 3750, matching 3855 VFO & 3854 Speaker is an attractive package using heavy gage aluminum panels. The front panel is a dark gold anodized design. The modes are SSB & CW. Band coverage is 160 to 10 meters with WWV 10 mHz receive (did not try xmit). The radio reviewed is model number 100348 possibly suggesting at least 348 were manufactured. Known model years were 1976 and 1977. The radio has dual digital displays reading out to 100 Hz. Tuning is analog with very little drift during a 15 minute warm up. Drift is about nil after 15 minutes during a two hour test period. The receiver is quiet and sensitive with reception on 75 meters during the summer time rated as excellent. The RF output was over 125 watts and the transmitter uses a pair of tubes labeled M-1000. I believe these 12 pin compactitron sweep tubes are 6DK6, but not sure. The optional VFO and the HF transceiver have both an analog and digital display that indicates to 100 Hz. The two digital displays are located on the transceiver. With the optional VFO, one can operate split frequency on the same band. The noise blanker is variable without much function, but reasonably effective. The manual notch filter is effective and allows a more narrow passband for reception of two close-in signals or simply reducing band noise. The speech compressor, RF ATT, VOX, adjustable CW sidetone and fast/slow AGC are excellent. The RIT control has an LED indicator and amount of RIT is displayed on the digital display. The radio comes standard with a 500 Hz CW filter. Considering the era, the radio must have been a top performer. I would rate the radio a 4.5, however either a 4 or 5 was available, thus the five (5). A picture is available at www.rigpix.com
