This radio kit will cover the AM radio band along with the SW radio band. Power for this receiver is 1.5 V DC for the filaments and 45V DC for the plate current. A D cell and five 9V transistor batteries wired in series will work to power this radio. A 2000 ohm headset or an audio amplifier is required. Requires two T-1T4_DF91 tubes (not included).

Difficult to tell. I built the kit but there's no way to determine the frequency you are on. I just know that one setting is for the AM band, and the others are for shortwave. I'm sure it covers at least the 5-10mhz portion of the SW bands.

Does it cover the 80 Meter [3.5-4 MHz] and 40 [7.0-7.3 MHz] Meter Ham Bands??

A good way to calibrate this radio would be to find the frequency-time broadcast station WWV - WWVA in Ft. Collins CO, and Hawaii on the lower bands of 2.5, 5, 10 MHz at night, and 15, 20 MHz daytime. It will give you the frequencies to calibrate your radio, plus time of day in Zulu time, plus weather info for mariners and "other related information" according to the announcer at the top and bottom of the hour. WWV announcer id a male voice while WWVA is a female voice There is also CHU in Canada, but I do not have their frequencies at hand. 73's de W4FJF.

These capacitors also have a code printed but it can be difficult to read. A magnifying glass and good lighting can be really helpful. If you have a multimeter that can accurately read capacitance, you can use the meter to identify the caps as well.

I had no problem with any of the parts or the wooden pieces. My only complaint is the drawings. The coil drawings are way too dark. Drawing the coil as black and the windings as dark grey in the coil winding instructions - I could barely make anything out. Using black and various grey tones for all the drawings is dumb. Just make it simple and make everything black and white. Thank God they included the schematic.

This was a fun kit to build... a couple of notes to really make this kit sing... you need a long wire... like 75 to 100 feet to hear the short wave bands. Also, these are battery tubes... so don't expect that orange glow... you can see it if you strain your eyes in a dark room, but don't expect that glow to double as a night light. I did add a couple of improvements to make tuning easier: I added a Philmore vernier dial to the tuning capacitor to reduce the speed of tuning - these can be very expensive - almost half the cost of the radio, but we'll worth it! I will also be replacing the 50 ohm regen control pot with a 10-turn 100 ohm potentiometer. Also kind of expensive, but it makes tuning a lot easier. Another thing about battery tubes... you don't have to wait for them to warm up... they started working instantly like transistors.

The wooden chassis and front plate are very poor quality. They are no where near rectangular and the cut is extremely rough. As for the construction, it is not too difficult and goes together rather easily. I was disappointed with the sensitivity of the completed product. I built a similar two tube (also 1t4's) radio when I was about 10 or 12 years old that had much better sensitivity. This was to be a nostalgic return to my childhood, but found it quite disappointing.

Fine kit but there is missing an alligator clip.
