Re: [Elecraft] Astron VS-35M Powwer Supply V-

How can you "Keep all of the transmitter power supply return current confined to the power cable between the rig and the power supply" when there is a path from the PS to the V- input of an accessory, through the case of the accessory, back to the ground bus, to the case of the radio, and from

My 70amp Astron has 1/4" lugs and they seem to make a secure connection. Do to my longer lead length (power supply on floor) I used 8ga wire. This was difficult to stuff into the K3S sized PowerPole. Even with the shorter leads that I use on contest expeditions along with a switching power supply

John and all, You can splice a short (3 to 4 inches) length of #12 wire to the #8 or #10 wire and it will not have negligible voltage drop due to the short length. Make certain you have a good tight connection at the splice point. 73, Don W3FPR On 4/11/2018 12:02 PM, j...@kk9a.com wrote:

I have used twisted thick wires to encourage magnetic cancelling as recommended by Jim Brown. The twisting also makes the cable easier to manipulate. I used 2 cores rescued from scrap household cable. David G3UNA > > On 11 April 2018 at 17:02 "j...@kk9a.com" wrote: >

I have a TGE Boost Regulator* connected to lead-acid batteries powering my K3. The boost regulator is set for 13.7V which drops to 13.3V during 100W CW key down. The device is connected to the radio with about 30cm (1 ft) of #10 zip cord and PowerPoles. I have had problems in the past with

I would appreciate it if the transceiver had bolted connections or at least double up the power poles What I have done in the past, (with cheaper radios) is to bypass the power connector, and solder heavy wires directly to the DC input pads inside the radio. The power supply end has ring

I have never seen the Powerpole adapter but that seems like and elegant solution. You could even use 6awg wire with that connector if you had a longer power supply/battery cable. John KK9A Phil Kane k2asp wrote: On 4/11/2018 9:14 AM, Don Wilhelm wrote: > John and all, > > You can splice a

The Kenwood TS590 runs about a foot of 12 ga connected to the power supply and then the rest of the power line is double 12 ga wires to the radio. Could you reverse that and run double wire until right before the power pole and then a short single wire into the radio? That would reduce the

I am contemplating building a 2 meter transverter based on a very low noise commercial100 MHz crystal oscillator that would result in a IF frequency of 44 MHz. Can the KXV3 et al be coerced into emitting 0 dBm outside the ham bands and the front panel display the transverter tuned RF frequency?
