Looks to be a good receiver but is limited on HF frequencies as it covers mostly short wave broadcasters and has gaps in band coverage. A favorite of mine is the Tecsun PL-660 and a newer version will be out, the PL-670 soon. These cover the whole of HF, 100 kHz to 30 mHz and have USB and LSB...

Tuning around on the 11 meter band and below, I found some interesting comms on 25.750 in AM mode. At first I thought it may be DEA or ICE but listening for a short it seems to be deer hunters. Talking about pursuit and having gun on the ready, you can see my confusion! Sort of a Texas drawl on...

Try using a different transceiver, this will let you know where the fault is originating. If the DTV box still acts up, then the TR7 is not the problem. Then it would be the coax, antenna or DTV box. I have Dish Network and have zero problems, only item in my home that overloads from RF...

Sounds like a SelCal jammer on top of Cuba's usual number station.... 73 mechanic

I could not find any such receiver on Amazon but a good antenna would bean outside wire, horizontal. I have one that is about 60 feet long, three to five feet above the ground. I hear most anything. 73 mechanic

I run several different powers supplies, my main is a homebrew 35 amp continuous with heavy cables. Works well with my 100 watt rigs. I also have a decent but cheap Samlex 20 amp but I renewed the rectifier diodes when it was still fairly new. I use a 12 amp with my HR2510, a no name brand...

There was one of these in our area once, would jam and play music on top of us. He was hit one night by axing his coax. Back on the air in three days with a new rig and his coax in a pipe! Out came the grappling hook and down with the tower! He finally quit when he caught wind of the tar and...

If you do not mind my asking, what did this cost you? I have one I would like serviced.... 73 mechanic

Finding RFI sources can be tough. The offending emitter may not be at your neighbor's house. Best way would be to DF (direction find) the noise source with a portable receiver, a short wave receiver will work fine. The closer you get the stronger the signal will be. If it is power line...

Late on this reply.... Several transceivers did not have an amp board installed. My Yaesu FT-101EE and my old Hygain 623s are examples. These rigs have vacuum tube (valves) for finals and do not need or want the amplification by design. You could use a D104 with the amp on these rigs but...

Not sure if this is on topic or not but I am looking for a simple DIY build of a sweep tube amp. An old friend of mine had a home brew single sweep tube amp that gave him about 25 to 30 watts out. I'll build a small one at first, then on to bigger things! Any guide to a good direction...

Citizens Broadband? is that not the same as splatter? 73 mechanic

And I thot CB was for communicating!? Now there are these amps and cutting limiters.... 73 mechanic

Just for the point of argument.... Yes a zero ohm resistor is the same as a wire jumper but then again it is not! Depending on the circuit used, a zero ohm resistor is used by design because a resistor can introduce other factors such as capacitance and inductance also to reduce 'noise' in...

IMD is most likely correct as 'skip' brings in all sorts of signals. When the cycle is high and conditions are good, one can hear all sorts of UTE signals including OTHR or Over The Horizon Radar. I hear this rapid and loud pulsing on many frequencies. Another is radiosonds or travelling 'pips'...

Ebay is the place, you can buy blue common anode displays for about 8 dollars.... 73 mechanic

May as well throw my 2 cents in.... Pretty quiet around here now, I have to call up on the phone to get the few old timers on the channels! Few truckers moving through with a couple of French-Canadians going across the U.P., truck drivers saving a few miles. I remember my dad's CB in the...

In the past week I have worked several stations from South America, Brazil and Chile, Quite a few in North America, all on ten meter. Good reports with the 8900! Still only listening on 12 meter as I have no antenna for that band but on my various wire and beams , sounds pretty good. Like...

Hi Retro.... What you wanted at the last would be fine with me. I'm in Michigan BTW, the U.P. eh! 73 mechanic

Jim, I meant to type Grant and not Lincoln! So if you still have the Grant, I'm interested.... 73 Mechanic
