HF military receiver/ 6 bands/ triple conversion  Time owned: 0 to 3 months
The R3110 (R35T) Romanian military receiver dates back to the 70s. It is a medium size transistorised set that uses both silicon and germanium devices. The lower three bands use double conversion and the upper three triple conversion. The front panel features main and band spread tuning with two small illuminated dial windows. The dial covers are heavy and thick plexiglas. BNC connectors are provided for tape recording, IF monitoring and AVC. There are line plus phones connectors of the type usually found in Russian sets. Power selection can be switched from batteries to external power supply with a connector available for the former. A calibrator circuit is also available as well as an AVC or non AVC selector for either voice or CW. IF selectivity options are 7,4,2 and .6kHz. the front panel meter is mainly a power monitor but can be switched also for calibration purposes. There is also a 2.5kHz audio filter switchable from the front panel.

I acquired this set from a seller in Poland who shipped it rapidly and well packed. He also maintained excellent communication during all the process and after I received the set. The R3110 as received included the main receiver, external power supply with connecting cable, Three battery boxes, one original long wire antenna and one Kulikov whip antenna with connector, two headphones, a small wood box with spare rubber seals, rubber switch covers, a multitool, spare fuses and lamps for the power supply and some battery cables. Everything seemed unused and still in paper wraps secured with cord. The whole setup seems like an NOS receiver plus parts.

I proceeded to clean everything first and eliminate some of that long term storage smell. A speaker was prepared with a 600-8 ohm matching transformer and connected to the phones terminal. The power supply was tested and found ok. This one was wired for 220VAC. After connecting the power supply and my long wire antenna I took a shot at it and turned on the set to find a fully working radio on all bands and well in calibration. The band coverage is:

Band I -1.5 to 2.5 MHz
BandII- 2.9 to 5.0 Mhz
Band III- 5.0 to 6.9 MHz
Band IV- 6.9 to 12.5 MHz
Band V- 12.5 to 21.1MHZ
Band VI- 21.1 to 31.1 MHz

The main tuning is smooth but covers a lot so the use of band spread when tuning nearby stations is helpful as well as when tuning SSB. The band spread is centered at zero and moved either left or right. Dial lights can be switched on only momentarily to see the frequency.

I found the R3110 a pleasure to operate. It is a good basic receiver. For casual shortwave listening the audio is surprisingly good considering that it was probably designed for CW and AM communications in the field. CW is excellent with a good stable BFO. SSB can be tuned using the BFO and here the 2.5kHz audio filter also helps. Sensitivity is excellent in all bands and the AVC does an excellent job with strong signals. I have not used the calibrator much but it is working. The IF filters work perfectly and provide excellent selectivity control. I was able to monitor both 40 and 20 meter SSB without problems. Of course, it was not designed for SSB so one has to tune carefully.

When the receiver arrived it was missing a dial bulb and the power connector dust cap. The seller provided both plus an extra bulb immediately. He also sent me the on-line manual. It is in Romanian but one can make out a loy of things and all the schematics are there. BTW the front panel is labelled in Romanian too but easy to figure out.

I removed the set from the cabinet ando found a very clean chassis inside that reminded me of my R392. The design has a clear Russian influence that also translates to German WWII designs specially in the band switch mechanism and general mechanical design.

As a military set for ham or shortwave listening applications the R3110 does an excellent job. Even if it is transistorized the 40+ pounds weight puts this receiver in the Boatanchor category. My only observation is the small dials but this is part of the receiver ruggedness.
