Re: [AMRadio] AM on 160m
Hi Ken, Yes, very much so, due to their lower noise levels (especially in the spring and summer, when thunderstorms are more prevalent in the US). I've had good success with 20W of carrier power or less, on 10M, when the band is in good shape. 73, Ellen - AF9J - Original Message - From: Ken Zuercher [EMAIL PROTECTED] To: Discussion of AM Radio in the Amateur Service amradio@mailman.qth.net Sent: Wednesday, June 04, 2008 10:59 PM Subject: Re: [AMRadio] AM on 160m SNIP! I have a Heath DX-40 which is more than enough for any cw contact but I haven't done more than test on AM. Do you think the higher bands will go with the lower power on AM? Thanks for the advice in advance!

[AMRadio] Capacitor tester
Has anyone on this list had experience with the Sprague TO-6 capacitor tester/analyzer? I started to cobble together a little supply and metering circuit for this purpose, but have a possible opportunity to get the TO-6. I'd appreciate any insight on the unit.

Re: [AMRadio] AM on 160m
Hi Ken, How much space do you have? If your tower is 50-60 ft. could you possibly install an Inverted L? Say 55 ft vertical (the more the better) with the rest horizontal out to about 160-170 ft and the end as high as possible. Feed that with 50 ohm coax and use a series cap in the center of 100-300 pico farads. If you will do that, you will be able to tune the thing on all bands with a good tuner at the transmitter. The downside is that it will be a better antenna for long distant communications and not as good for distances out to 500 miles. I have 44 ft. vertical and the rest horizontal and it works on 160 both close in and at a distance (as many radials as you can put in). On 75 meters, however it is distance dependent. Close in stations are weak, stations out over 500 miles do well. As for power, the DX 40 will have trouble on 160 and 75 on AM in the evening. However on 40 and above you will make adequate contacts. On CW you will do fine on 75-10 and ok on 160. I have a 40/75 meter dipole (the poles support the ends as high as the center), the inverted L plus a 5 band beam for the upper bands. I find the L works fine on the upper bands. For transmitters I use a BW 5100B for SSB, a BW 5100 , Globe Champion 300A and a Globe King 500A. On the upper bands, power is not that important, but on 75, especially at night, it is. CW is much more forgiving than AM so take that into consideration. The more work you put into the antenna the better the payoff no matter what the transmitter. 73 Jim/W5JO - Original Message - From: Ken Zuercher Jim, If I had a little more land, I'd put up dipoles also. I am however using half slopers on 40,20, and 10 meters. the longest is only 32 feet. The 40 meter unit tunes well on 15 also. i haven't worked anyone on 15 as I haven't been around when the band is open. I am just about able to put up a 75 meter half sloper to a point on a tree from the tower. What do you use to tickle the dipoles? I have a Heath DX-40 which is more than enough for any cw contact but I haven't done more than test on AM. Do you think the higher bands will go with the lower power on AM? Thanks for the advice in advance!

RE: [AMRadio] Capacitor tester
Rick,, I have a Sprague TO-6A, love it! Test caps for leakage and insulation resistance at rated voltage. You will never believe in reforming old electrolytic caps after using a good cap analyzer. BBOD's from R-390A's fail like crazy. Makes restoration of old boatanchors easy, just gotta get rid of a few old caps. 73's wd8kdg Craig -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Brashear Sent: Thursday, June 05, 2008 8:04 AM To: 'Discussion of AM Radio in the Amateur Service' Subject: [AMRadio] Capacitor tester Has anyone on this list had experience with the Sprague TO-6 capacitor tester/analyzer?

Thanks Pete and all the others who replied to the TO-6 question. It's obviously a worthy piece to be added to the arsenal. Rick/K5IAR I've had a TO-6 for years. Great piece of test equipment.
