KRIS Big Boomer amplifier input tune....

$

OK, I'll start off with the story from the beginning. So I have received a Kris Big Boomer box and have been messing with it for quite some time now. When I first got it, it had a hum in xmit, but was getting full power. So after having a friend of mine replaced the filter caps and fixed some other odds and ends, after putting it back together I was only getting half the wattage. So I took it back to him to check the tubes. I was there while he was looking it over and he was explaining to me...

The Icom IC-7300 HF rig is now available for purchase at about $1500.
[​IMG]

This interesting rig is one of the few rigs that is architected using direct RF sampling instead of the traditional superhet design. Other features include a touch screen control, real-time spectrum display and audio scope. While I haven't seen the rig in person yet, I plan to go to HRO and try it out as soon as it's in stock.

Is anyone planning on...

L21 Frequency mod for MB8719

$

Hello all,

Back at it again.

There seems to be little talk about this modification. This is a strange mod in which you place a variable resistor from L21 to PIN 10 of the MB8719 to achieve a 128 upward channel shift which is amazing compared to the usual 64 upward shift you get from simply grounding pin 10. I have encountered this mod in many of the MB8719 radios I've fixed and I usually scuff at it and remove it without really looking into it and seeing if it's a legitimate mod with...

Texas Star DX-350HDV Why?

I picked up another DX-350. It has DEI's. When I hook up any CB or Export radio, It has high SWR on channels 1-18, like real high. All the other channels, it's flat. I'm driving around a watt or so, into a Gainmaster. My analyzer shows flatness. My other 350 with Toshiba's, behaves normally. Is this a DEI thing? Oscillations?

Just because you can fix a 35 year-old ham transceiver does it mean you should?

In this case, my answer was yes. The Kenwood TS-930S is famous for several kinds of annoying breakdowns, most especially in the power supply. The fans are controlled by a temperature-sensing circuit. The sensors drift with age, driving up how hot it must get to activate the fan on the power supply and on the power amplifier, both. Eventually, the fans will only come on at meltdown temperature. Predictably,...

I was asked by a few people how to do this mod, so I figured I'd just post it up.

Please don't copy and paste this mod to other sites/forums, but feel free to link to it.

Also applies to:
Uniden 78
Cobra 25 & Uniden 76 mod is similar, although you'll need to cross reference against the schematic.

1: change the final to a 2sc1969
2: change the driver to a 2sc2314.
3: change the electrolytic capacitor by the audio IC (C42, 1000uf) to a
3300uf, 16v.
4: Take a turn off the output...

Older Texas Star D.C. 350 ssb delay

I have a question or three about the delay on my older dx 350.
Amp info, older Bi-lateral 4 power (Texas Star) dx350. It does have 4 power levels, on AM, on ssb it has 2. Ssb power levels are the 2 lowest of the 4.
My thoughts, I'd like to have a permanent/ automatic ssb delay. Thereby having acces to all 4 power levels while on ssb.
Is this possible? It looks like I could run a wire from the power switch to the positive leg of C4. That way when the amp is on the delay works.
I want to...

If anyone has it that cares to comment......

I'm thinking of getting this one. I know there are some pretty old threads that talk about it but some forums don't like "resurrection of dead posts" so much..... so I wanted to ask......

Is the book geared towards teaching you how various circuits work? How to troubleshoot? Just a collection of "tips and tweaks"? Would you say that it is "as in depth as the reader cares to go"?

I've been watching some repair threads the wind up...

There seems to be a growing trend in removal of our Second Amendment rights, the latest of which is these "Red Flag Laws" being promoted. Many counties are declaring 2nd Amendment Sanctuaries, even some states are pushing for removal of concealed carry permits. Latest of those is Ohio. I believe OK has done so also, possibly KY, too!

With the "Mass Hysteria" over "Mass Shootings" elected officials on both sides are pushing this unconstitutional law. Now, I know this will bring out a lot of...

Well fellas, I'm wanting a replacement mic for my anytone rigs or at least my base because I don't much care about for the stock mics. The SL41 is an electret so I believe it'll mate nicely with the anytone but problem is they're all sold out and when it had some in my possession I didn't do they wise thing to keep one.. Anyone have a good condition sl41 they'd like part with? Or know who might possibly stock one?
