A while back tx star got busted by Bbi using fake Toshiba 2879 transistors, Lesters custom also offers the Chinese Toshibas as an upgrade. What do we know about the source of these parts and what about the performance? .

I have been doing some research in to slow scan tv ever since a friend told me about activity on 11 meters at the Queen Wilhemena ham fest earlier this month. Today I made a simple 3.5mm to 3.5mm audio cable and plugged it in to the Ic-7300's headphone port, the other end plugs into the...

I like to recap old mobile sweep tube linears, useless to most people but I really enjoy them. The thing is money is tight these days and high voltage capacitors are not cheap. Many of the mobile amps I have use 500 volt capacitors in the filter circuit. The Golden Falcon 150 (1x2 8950) I have...

I have had this old Digiscan Ufo laying around for about a year and a am ready to install in my restored 138xlr, but the manual I can find is for an earlier model. My Digiscan has only 2 movable blocks and 9 switches not like the 13 movable blocks pictured in the manual I have been able to find...

I have been looking at these for a month or so now It seems too good to be true https://www.andradsupply.com/ss3900.php It looks like the ranger made classic, maybe a distributor in Europe has them.

What a machine, 10 toshiba 2879 transistors staged to operate as a 2 pill , 8 pill or a 2 driving 8. Any thoughts or anecdotes on this rare bird? (Not posted in the Armature Linear section)

I am having trouble with an alignment on an old president Grant I picked up. The trouble is I am not able to get a frequency reading on tp21, the bare lead of r101. What am I doing wrong? The radio works properly I just want to get the alignment spot on

Matt over at radio garage did a nice review on the 99n1. I would like a set of those rt5s t go in my 69vhp.

Well this one is my personal base station, Saturday morning I noticed It was putting out very little power in am and fm mode, ssb seems unaffected. The middle leg of Q54 q54 only reads 1.8 volts in am and fm with both internal variables and rf power knob at max. In ssb the center leg of q54...

I have a nice galaxy 99v tiawan that had several bad electrolytics. After the recap I have discovered vr 21 does not finction as it should. Also the built in frequency counter is off a little when using the sidebands

Just what the title says. I sold a 29 fm chrome today and the customer wanted a geen chanel display and traditional bulb in the meter. I proceded to unsolder the old channel display and when it came time to put the new one in place I was having trouble getting the pins to line up. These new...

Its tough to find Info on these old kits sometimes.

I have an old 2527 that just won't swing on am. It had q32 removed and tye resistor diode swing mod but that wasn't helping it any so I restored the limiter and removed thw swing mod for now. It will key about 12 watts on am with verry little pep swing. The best swing I can get it to do is 1...

During the last two world wars ham operators were ordered to maintain radio silence until the end of war and cb radio was not around yet. With the escalation of hostility toward Russia and China a similar situation seems somewhat possible today. Perhaps ham operators during the world war came up...

A freind of mine brought me a Uniden Washington modified with 2 crystals on the bottom of the board for extra channels, also an open clarifier. The clarifier works perfect on startup but after about 5 min of warmup the frequency drifts up to 27.**54 or 400 cycles high and the clarifier will not...

I have decided to go with replacment multi section capacitors to simplify the process. My first question Is can I use this 20 20 20 20uf 475v In place of a 10 10 10 10uf 450v. I want the extra voltage rating to protect against the start up surge that Nomadradio warns of.

I picked up a nice galaxy 95t2 in trade and it functions well on all modes other than fm. The radio transits good carrier but no fm audio and I have tried adjusting vr5 fm deviation with no effect. Here is a picture of the component side of the board if anything looks out of place.

One of the locals I talk to every morning purchased a 150 amp transformer power supply to run his linear amplifiers. The problem is this power supply puts out 20 volts and we need to get it regulated down to around 15 volts. What is the best way to do this?

Just wondering if anyone on the fourum had heard any news on when the fm cobra models would be available? I have done some searching and I have not found any info.
