Hi Conrad, you could try maybe manualexchange, wiltron or the hp-agilent groups, all on groups.io Best regards Rien

It has been a while that the 2320.830MHz GB3MHZ beacon vanished due to problems. Is there any expectancy that the beacon will return? It is a nice condx indicator for 13cm. Though condx have been poor

You can also apply for free samples, they aren't difficult is my experience 73es Rien PA0JME Op 13-9-2021 om 10:26 schreef Neil Douglas via groups.io:

try utsource but beware currently shipping is over the edge (to my mind) 73es Rien PA0JME Op 11-9-2021 om 10:39 schreef militaryoperator via groups.io:

Hi Ken, you might be right. If one imagines some form of delay or phasingline, there are discrepancies. The circumference of the outer loop should be a wavelength lambda, i.e. lambda = 2 x pi x R, and

A belgian radiofriend of mine just sent me this link and asked if this is a usefull antenna? https://nl.grandado.com/products/2-4-10-5g-uwb-ultra-wideband-antenne-module-uwb-uwb-antenne-puls-antenne-2

A bit further datasheet shows Input Impedance and Bias Current Input bias current is measured with the output held at 1.4V. As with any simple NPN differential input stage, the LT1016 bias current wil

Hi I am not familiar with both devices but took a glance at de 1016's datasheet. It tells me that inputbias current is about 10uA. If Vss is at ground there can be no bias current at all unless input

Hi all, My experience 0.25 inch at 1296MHz and 120 Watt RF is OK, it certainly is better since 0.141 will become to hot too Short ends (20 to 30cms) can be found at fleamarkets, often used as phasing

Yes, but the tower is just some 250m away hi, wil try to test with a local station in Belgium tomorrow at 25km 73es Rien Op 10-1-2021 om 18:15 schreef John Fell:

Thanks for the info John, I know condx were bad but normally it recovers quickly or there is the occasional plane reflection, but now nothing at all but for the spurious noise from telephone towers. 7

Hi all, normally I try to monitor the GB3MHZ beacons (currently 23, 13 and 9cm) which present a good condx indication. The beacons are roughly 300km distance from my station. The past few days condx w

Hi all, condx from PA to UK seems below normal, GB3MHz on 2320.830 (dx=298km) is about 6dB weaker than normal, any luck sofar?? Best regards Rien Op 26-11-2020 om 13:17 schreef Nick Gregory G0HIK via
