Kihwal's state-of-art equipment

R-392/URR
General coverage HF receiver by Collins. It was acquired in 1985 as a first "working" HF receiver for SWLing. There is a homemade 24V power supply to run this fine receiver.
NRD-143
General coverage HF receiver by JRC. This is an exact copy of Collins R-388/URR. The meter is not original. This is also a fine receiver that is fun to operate.
40m mono band receiver. I modified RH07 pocket 40m receiver and put it in this enclosure. This is a fun receiver, but the ceramic filter is barely enough for SSB reception in this busy band.
Homemade 1-tube (6BD6) HF regenerative reciever. I remember listening to 5Mc standard signal and 40m CW QSOs.
R-390A/URR
Another fine general coverage receiver designed by Collins. It is supposed to be much better than R-392/URR, but I like R-392 better.
Techinic-5
HF all band transceiver by Bando Commnunications. It supports all bands except 160m. This is an early version that uses PTO in its VFO unit. I added one more 6146B. Very similar to Kenwood TS-530
TS-505 D/U
This is a VTVM with RF probe.
Galaxy 300
This is a tri-band HF transceiver by WRL. It was a low cost rig but very well made.
Glowing 0A2
0A2 is a voltage regulation tube. These tubes glow in pretty colors depending on the type of gas it contains. 0A2 does purple.
