 RADIOANQ - Hy Gain Galaxy R-1530 Receiver For Sale  
For sale is my Hy Gain Galaxy R-1530 Receiver. This is a very rare receiver that appears to be fully working. The synthesizer locks on all bands. This radio covers 0.1 to 30 MHz. the 1530 is the industrial/military version of the R-530. It has ALL FILTERS in it: AM Filter, CW Filter and USB/LSB filters are all present. These are all solid state receivers that were made during the late 60's / early 70's. Here is your chance to own a very rare radio that is fully working and looks good as well. Price is $500 You will need an external 8 ohm speaker for it. I prefer an "in person" deal at my QTH just south of St. Louis, or, I can meet at a reasonable distance as well as free delivery to Dayton. I will ship at the buyer's expense. I can accept cash, Venmo, Zelle, PayPal and credit cards. Buyer to pay fees. Please call/email with questions. I can send more pix and videos.

 MISC - WTB Icom 730 CW filters FL30 and FL45
These are two solder ins on the 2nd IF board. To get to that board remove the top cover. On the right side of the set there should be two screws holding a hinged assembly with two circuit boards attached. Lift the right edge of their metal base plate and tilt it up to the left. Near the two hinges on the left the two rectangular filters are located. You will have to lift the PCB
to unsolder them.
Thanks
