Bob I am constructing a DXE style receive 4 square using shortened verticals with ICE 135B preamps for each active antenna. I will use a small choke and resistor is series at each preamp to impedance
Dan A couple of thoughts... When transmitting, is the RCS-10 antenna switch inadvertantly changing (switching) antennas (ports) during the transition from receive to transmit, possibly RF getting int
Dan I understand that your 160 meter station is/was working until you introduced the 374A to the system. If this is the first time you have manually loaded up the 374A on 160 meters, it may be possib
Has anyone heard from Dan ? Did he get the problem solved ? Paul - WB2NMI Excellent suggestion. Since the amp has an swr meter you can easily verify if it is tuned to 80 meters. Test it at the lowest
Dan Its good that the list has supplied useful suggestions for troubleshooting. To reduce the risk to the RCS-10, you may want to bypass it and connect directly to the inverted-L for this test. I exp
Dan Quick NEC analysis of the 160 meter inverted L antenna: Total length of 167 feet. SWR to 1.2 to 1, assumed center freq of 1.85. 2 to 1 SWR points are at 1.80 and 1.90 Mhz. Reactance is 250 ohms,
Dan A little hard to tell what you mean by "port". Do you mean the RCS-10 port or a port on the transceiever ? I understand you to mean that when you bypass the RSC-10 antenna switch and feed the inv
Thanks for the heads up. Just worked them on 160 with 100 watts and the inverted L. S9 here in Nothern NJ. Paul - W2NMI According to their QRZ page, this group's DXpedition is about to end (they show
Worked Luke VK3HJ here in NNJ at 1824.500 at 6:50 AM this morning. Signal 55N both sides. I was running TT Orion, 100 watts into a HyGain 18HT vertical with inverted L kit. Also using the transmit an
Elliott Supply has the 2N5109 in stock: https://www.elliottelectronicsupply.com/transistor-94165.html Paul - W2NMI I remember about a year ago a discussion not to buy the 2n5109 transistors from E-Ba
