Yeah CK is right about that. Also be advised RFI Radio Frequency Interference has frequencies that are louder than other frequencies. So some frequencies will have louder stronger noise levels, and some frequencies little or no interference levels. Measuring the local vehicle area as compared...

These ABS1600 antennas were advertised to take 5kw, no way. Mine had electrical intermittent internal connection, at 1kw. Shakespear replaced the antenna, which is ok. But never used again. Jay in the Grate Mojave Desert

Most off road four wheel drive guys use CB Radio and most also use a linear amplifier. We used GMRS type hand held radios on a quail hunting trip, being in site with everybody we still could not talk to each other. That night we thru the GMRS radios in the fire. Used our ham two meter hand held...

Hello: Is this the base unit of a Hy-Gain SPT-500? Jay in the Grate Mojave Desert

Do you mean the four ground plane radials mounted at the base of the antenna. Oh I see its the top four half circles at the top of the antenna. I would suggest 18 inches, I don't belive its to critical. These are called a Top Hat or capacitance hat, it increases the antennas inductance. Jay in...

5 Miles at CB Frequencies is 43 dB attenuation. The diagram is all most correct, the series resistor needs to approx 3.1 K Jay in the Grate Mojave Desert

Hello All: The SSB 27 was a tube SSB only, 6 channel radio that almost put out 20 watts. The next radio was the SSB46, I don't know how close they were to each other never looked at that. These radios were made in the mid west, by DynaScan or Dyna something same group that made the cobra...

Yeah a great subject. A quick and easy way to verify the audio amplifier circuit in a radio is to touch the center pin on the volume control, if you hear a hum or noise this verifies the audio circuit is working. Try not to touch any thing else in a tube radio as high voltages are in there. I...

Continued from post #11: SSB contacts from all over the country on CH16 LSB were easy and all over. Maybe SSB had fewer stations then. But a lot of fun. A Johnson Messenger 350 and a Palamor 150 amp was such a joy operate on Dads Boat, during slow work times. I keep an ear out on CH16 LSB and...

Yeah all good stuff. In the late 1960's Dear ol Dad bought a WWll army crash boat, converted into a tuna fishing boat. It had old WWll radio equipment and such, loran, automatic direction finder, manual direction finder and more. Some of this stuff was old and wore out. Dad replaced the manual...

I will try to be there, yeah the old days. Use to slide down 5, 10, and even 15Kc from CB 16 oh the memories.

I had a PM3 100 Amp unit and it ran my 4 pill Messenger 3 just fine. But probably not the 8 pill Amp. Jay in the Grate Mojave Desert

The first posting photos shows a never seen by me, CB antenna of some foreign type. It copied the Hy Gain type base assembly, using a two point mount. As the single point mounted base antennas broke off very easily. Surly there many antennas not popularizes that fadded Into opsecurity. The...

The reason we shoot a 88 Mag is because they don't make a 89 Mag, yet. While travelling in Montana / Wyoming a few months ago had to stop and clear off the wind shield of the truck, there was a bunch of guys getting ready to go deer hunting unloading horses and packing them up. I walked over and...

Thank you greatly appreciated, looked in everything except CB Radio swap. Jay in the Grate Mojave Desert.... startin to get a little warm

Hellon All: Just the other day saw a guy selling new type Channel Guard IF Filters, just like the ones sold by CBC. Were is the posting seems this site is user hostile to super CB'ers. Jay in the Grate Mojave Desert

I want my meter to go all the way over. Jay in the Grate Mojave Desert

Wow aint dat a coinsdance, the same watt meters I have, and yeah my Dad used his Drake W4 with his Contex 500 linear Amp back in the 60's and 70's. I picked a Transel meter off e-bay years and yeas ago. Back in the 60's only a few watt meters were available and there quality was not as good as...

Hello tchr01: Gee whiz never heard that type of noise before. If its not coming from the house after the battery test, might want to drive around the neighbor hood and sniff around and see what you can pick up. We had frying bacon power line noise come in one day but it was varying in signal...
